Grammarly for Small Business: Write Better, Faster

Direct answer:

Direct answer: Grammarly for small business is best thought of as a safety net for everyday writing, not a replacement for thinking. It sits alongside your email, Word documents and browser, flags spelling and grammar slips, suggests clearer phrasing, and helps a small team sound consistent. Used with a few sensible rules, it is genuinely useful for emails, quotes, listings and customer replies. Used blindly, it will happily polish a message that is still wrong, rude or misleading, so the human check matters more than the tool.

If you run a small firm in the UK, you probably write more than you realise. You answer enquiries before breakfast, send a quote between jobs, reply to a review at lunch, and draft a social post while the shop is quiet. None of that writing is glamorous, and all of it shapes how customers judge you. A quote with three typos does not prove you are bad at your trade, but it plants a doubt. A polite, clear reply to an unhappy customer does not fix the original problem, but it often stops it getting worse. Grammarly helps with that middle ground: the everyday writing where professionalism is won or lost in small details.

This guide is written for owners and small teams, not for linguists or large marketing departments. It explains what Grammarly is, where it actually works, how to set it up for a handful of people without creating a mess, and how it helps with the four kinds of writing most small firms do every week. It also covers pricing in honest terms, what to think about for UK GDPR, and where the tool falls short. There are no miracle claims here. If a writing tool promises to transform your business overnight, close the tab.

What Grammarly is, in plain terms

Grammarly is a writing assistant. You type or paste text, and it suggests corrections and improvements. At its simplest it works like an advanced spellchecker. At its more useful level it points out unclear sentences, passive phrasing, repeated words, inconsistent tone and punctuation problems that a normal spellchecker misses.

It does not know your business. It does not know that Mrs Patel prefers email to phone calls, that the boiler part is on back order until Thursday, or that your café is closed for a private hire on Sunday. It only sees words on a screen. That limitation is also its strength: it is consistent, patient and never tired. It will flag the same missing comma at 7am and at 11pm, which is more than can be said for any of us after a long day.

For a small business, the value is rarely in one dramatic correction. It is in the accumulation of small saves: the “your” that should have been “you’re” in a quote, the double negative in a complaint reply, the sentence that ran on for five lines in a proposal. Customers rarely praise good grammar, but they notice bad grammar, and they notice it most when money is involved.

Grammarly also offers tone suggestions. It might suggest making a message sound more confident, more friendly or more formal. Those suggestions are useful as prompts, not as orders. Tone is a judgement call, and a tool that has never met your customer cannot make it for you. If a suggestion feels wrong for the person you are writing to, ignore it. That is not a failure of the tool; it is you doing your job.

Where Grammarly works

One of the reasons Grammarly suits small firms is that it does not ask you to change where you write. It meets you in the tools you already use.

In a web browser, the Grammarly extension checks text in Gmail, Outlook on the web, social media sites, web forms and many other places where you type. That covers a huge share of small-business writing: enquiry replies, social posts, review responses and messages sent through a website dashboard. If you write most of your customer communication in a browser tab, this is where you will see Grammarly most often.

In Microsoft Word, Grammarly works as an add-in or through its own editor, depending on how you set it up. This matters for longer documents: quotes, proposals, tender responses, terms and conditions drafts, and letters. Longer documents are where small errors hide, and where a second pair of eyes is most valuable. Grammarly is not a substitute for reading a proposal aloud before you send it, but it catches the slips your eyes skip because you have read the same paragraph four times.

In Google Docs, Grammarly checks your document as you type. For firms that collaborate in Docs — a partner drafting a proposal while an assistant adds prices, for example — this keeps everyone working in the same place without copying text into another tool for checking.

On Windows and Mac, the desktop app can check text in many other applications. Email clients, notes apps and messaging tools vary, so it is worth testing the exact tools your team uses during a trial rather than assuming everything will be covered. Make a short list before you start: your email tool, your word processor, your social scheduler, your CRM notes field. Test each one. If Grammarly does not work well in one of them, you still have a choice to make, but at least it is an informed choice.

There is also a mobile keyboard option. For owners who answer customers from a phone, this can help, but be honest about how you write on a phone. Short, rushed replies benefit most from a quick check, and they are also where autocorrect causes the most trouble. Grammarly on mobile is a backstop, not a reason to send messages without reading them.

The practical point is this: Grammarly is most useful when it is switched on where you actually write, not just installed somewhere impressive. A tool that lives in a tab you never open will not save a single quote.

Setting up Grammarly for a small team, step by step

Setting Grammarly up for one person takes minutes. Setting it up for a team takes a little more thought, and that thought pays off. The goal is consistency without rigidity: everyone sounds like the same business, but nobody sounds like a robot.

Step 1: Give everyone their own account

Start by creating an individual account for each person who writes to customers. Do not share a login. Shared logins mix up personal dictionaries, snippets and writing history, and they make it awkward to remove access when someone leaves. If you use a paid team plan, you will have an admin area where you can add and remove seats. Keep that list up to date. It is a small admin job, but it is the same discipline as collecting keys when a member of staff leaves.

Step 2: Set the language to British English, for everyone

This sounds obvious, and it is the step most teams skip. Go into settings and set the language to English (UK) on every account. This aligns spellings for organise, realise, colour, licence as a noun, and the other small differences that mark a business out as British or American. Check it again after any update or reinstall, because defaults have a habit of drifting back.

Step 3: Agree a short style guide before you switch anything on

A style guide does not need to be a twenty-page document. For a small firm, one page is plenty. Decide, as a team:

• How you write your business name, and whether you use Ltd, Limited or neither in everyday emails.
• Whether you write dates as 12 May or May 12.
• How you write prices: £250, £250.00, or £250 + VAT, and when VAT is mentioned.
• Whether you use “Hi Sarah,” or “Dear Ms Jones,” for first contact, and when you switch to first names.
• Words you always spell a particular way: trade terms, product names, local place names.

Write these decisions down somewhere everyone can find them — a shared document or a pinned note — and then mirror them in Grammarly. The tool has a style guide feature on suitable paid plans that lets you set preferred terms and flag banned or discouraged words. If your plan does not include that feature, a shared document plus a personal dictionary still gets you most of the way there.

Step 4: Build a shared dictionary of your trade words

Every trade has words that a general writing tool will flag: surnames, street names, product codes, materials, qualifications and brand names. When Grammarly flags one of your normal words, add it to the dictionary instead of ignoring it every time. Do this as a team habit in the first two weeks. After that, the false flags drop sharply, and people stop ignoring real flags because they are tired of dismissing the same trade term.

A trades firm, for example, might add boiler makes, pipe sizes, certification names and supplier brands. An estate agent might add street names, development names and terms like freehold, leasehold and chain-free. A café might add dish names, supplier names and allergen terms. This is unglamorous work, and it is exactly what makes the tool feel like yours rather than a generic checker.

Step 5: Set brand tones, carefully

Grammarly lets you set tone preferences, sometimes called brand tones on team plans. Use this sparingly. Pick two or three tones that describe how your firm should sound to customers: friendly and professional, clear and direct, warm but not casual. Do not pick six tones and expect the tool to resolve the contradictions. Tone settings are a guide for suggestions, not a personality transplant. If your firm is a funeral director, “playful” is not a tone to enable, however friendly you are in person. If you run a skate shop, “formal” will make every social post sound wrong.

Test tones on real messages before you roll them out. Take five recent emails, run them through with the new tones, and see whether the suggestions help or hinder. If the team starts ignoring tone suggestions, the tones are wrong, not the team.

Step 6: Create snippets for the sentences you write every week

Snippets are saved blocks of text you can insert with a shortcut. They are one of the most practical features for a small firm, because so much business writing is repetitive. Good snippets are not copy-and-paste scripts that make every customer feel like a number. They are starting points that save typing and keep key information consistent.

Useful snippets for a small firm might include:

• A polite acknowledgement: thanking a customer for an enquiry, confirming receipt, and saying when they will hear back.
• A quote follow-up: a short, friendly check-in a few days after a quote, without pressure.
• A review reply opener: thanking a customer for a review, tailored with a placeholder for their name and detail.
• Directions and practical details: parking, access, opening hours, what to bring to an appointment.
• A closing line with contact details and next steps.

Keep snippets short, leave placeholders for names and specifics, and review them every few months. A snippet that still mentions Christmas opening hours in March is worse than no snippet at all. Assign one person to own the snippet list, even if everyone can suggest additions.

Step 7: Agree the rule for accepting suggestions

This is the most important step, and it costs nothing. Agree as a team that nobody accepts every suggestion without reading it. Grammarly suggestions should be treated like advice from a careful colleague: usually helpful, sometimes wrong, occasionally unhelpful because it lacks context. The person sending the message is responsible for the message. That rule protects you from the two common failures: blindly accepting a wrong correction, and blaming the tool when a message goes out with an error you could have caught.

A simple team checklist for this setup looks like this:

That table is worth printing or pinning. Most Grammarly problems in small firms are not technical problems. They are setup problems: wrong language, no dictionary, shared logins, or a team that was never told how to use suggestions sensibly.

How Grammarly helps with everyday writing

Theory is fine, but small firms care about Tuesday morning. Here is how Grammarly helps with the four kinds of writing you do most, with worked examples.

Emails: the bulk of business writing

Emails are where Grammarly earns its keep. They are frequent, rushed and consequential. A short enquiry reply might decide whether a customer books, and a long email about a problem might decide whether they stay.

Grammarly helps emails in three ways. First, it catches typos and grammar slips that creep in when you type fast. Second, it flags unclear sentences: the sentence that made sense in your head but will confuse a customer who does not know your internal shorthand. Third, it prompts you about tone: a message that reads as blunt when you meant to be efficient, or overly formal when you meant to be warm.

Consider a café owner replying to a customer who asked about booking a table for a birthday. A rushed draft might read:

“Hi yeah we can do Saturday but need to know numbers and if you want the back room its £50 deposit let me know asap thanks.”

Grammarly would flag the punctuation, the run-on structure and the abruptness. A revised version, still in the owner’s voice, might read:

“Hi Sarah, thanks for getting in touch. Yes, we can do Saturday for your birthday booking. Could you let me know how many guests you are expecting, and whether you would like the back room? There is a £50 deposit for the back room, which comes off your final bill. Let me know what works for you, and I will hold the table.”

Nothing in that revision required genius. It required a pause, a few commas and a clear question. Grammarly prompts that pause. The owner still decides the deposit, the room and the tone. The tool just stops the rushed version from going out.

For longer emails, read the message aloud after accepting suggestions. If a sentence sounds odd when spoken, it will read oddly too. Grammarly cannot hear your voice; you can.

Quotes and proposals: where errors cost money

Quotes and proposals deserve more care than any other business writing, because they are both a sales document and, often, part of a contract. A spelling mistake in a quote does not change the price, but it changes how a customer feels about trusting you with a larger job. A missing word can change meaning: “excluding VAT” versus “including VAT” is not a typo, it is a different price.

Grammarly helps here by catching the surface errors so you can focus on the substance: Is the scope clear? Are the exclusions stated? Is the timescale realistic? Is the payment schedule fair? Those are human questions, and no writing tool can answer them.

Take a trades firm sending a quote for a bathroom refit. A draft paragraph might read:

“The works includes supply and fit of shower, tiling to walls and floor, and disposal of old suite. Price valid for 30 days, payment 50% upfront and balance on completion, excludes electrical work beyond existing points.”

Grammarly would likely flag “works includes” for subject agreement, and might suggest clearer punctuation. More importantly, the act of reviewing suggestions forces a second read, and on that second read the owner might notice that “excludes electrical work beyond existing points” needs a plain-English explanation for a customer who is not a tradesperson. A clearer version might add: “If you want extra sockets or moved lighting points, we will price those separately before we start.” That addition is not a grammar fix. It is a business decision prompted by a second look, which is often how Grammarly helps most on important documents.

A useful habit for quotes: run Grammarly, then do a separate facts check. Read every number, date, name and price again, slowly, without looking at grammar suggestions. Grammarly checks words; only you can check numbers. For more on keeping everyday business writing organised, see how a content calendar can stop last-minute rushes in this guide to an AI content calendar for small business.

Social posts: short, public and unforgiving

Social posts are short, which makes people assume they need less care. In fact they need more, because they are public, shareable and hard to retract. A typo in a social post is not a private embarrassment; it is a screenshot waiting to happen.

Grammarly helps social posts by catching the obvious before you publish: the wrong “there”, the missing apostrophe in a business name, the hashtag that merged two words in a confusing way. It also helps with clarity. Social posts that try to say five things at once usually say none of them well. A suggestion to shorten a sentence often reveals that the post had two ideas competing for attention.

An estate agent, for example, might draft a listing post as:

“New to market!! 3 bed semi in great location close to schools and station must see wont last long call now for viewings.”

Grammarly would flag punctuation and suggest a clearer structure. A revised post might read:

“New to the market: a three-bedroom semi-detached house close to local schools and the station. Viewings are now open — message us to book a slot.”

The revised version is not more exciting, and that is the point. For a listing, clarity beats excitement. Customers need bedrooms, location and how to book a viewing. Exclamation marks do not sell houses; clear details do. Tone suggestions can help here too, but be careful: a tool suggesting a more “engaging” tone might push you towards hype that does not suit a serious purchase. Keep the voice of your firm, not the voice of the tool.

For social posts, also check facts separately: dates, prices, opening times and addresses. Grammarly will not know that your open day moved from Saturday to Sunday. If you are responding to customers publicly, the same care applies to replies. For a deeper look at handling public customer messages, see this guide to AI-assisted Google review replies.

Customer replies: where tone matters most

Customer replies — to enquiries, complaints, reviews and questions — are where tone suggestions are most useful and most dangerous. Useful, because a tired or defensive reply can escalate a small problem. Dangerous, because a generic polite reply can sound dismissive when a customer is upset.

Grammarly can flag a reply that reads as abrupt. It cannot tell whether an apology is appropriate, or whether you should offer a refund, a replacement or simply a clearer explanation. Those decisions belong to you, and they should come before you worry about commas.

Consider a trades firm replying to a customer who is unhappy about a delay. A defensive draft might read:

“As explained before the part is delayed and its out of our control we will come when we can.”

Grammarly would flag grammar and tone. A better reply, written by a human who has taken the suggestion as a prompt, might read:

“Hi James, I am sorry for the delay, and I understand this is frustrating. The part we need is delayed by our supplier, and I do not yet have a confirmed delivery date. I will update you by Thursday, even if the news is that we are still waiting, and we will prioritise your job as soon as the part arrives. Thank you for your patience.”

That reply is longer, but length is not the point. It apologises without grovelling, explains without blaming the customer, gives a concrete next update date, and makes a clear commitment. Grammarly did not write that. A person did, after the tool flagged that the first draft sounded dismissive. That is the right division of labour.

For review replies, the same principle applies. Thank the customer by name if you can, refer to a specific detail, and avoid sounding like a template. Snippets can help you start, but the middle of the reply should be specific to that customer. A review reply that could apply to any business will be read as if it applies to none.

Pricing: what to expect, without pretending prices never change

Grammarly has a free tier and paid per-user plans. That is the stable fact. The exact prices, what each plan includes, and whether there are team discounts or annual billing options change over time, and they can differ by region and by the plan you choose.

This guide deliberately does not quote specific prices as settled fact, because a price copied into a blog post can go out of date within weeks, and a small firm budgeting from an old figure will be misled. Before you budget, check Grammarly’s current UK pricing page directly, and check what is included in each tier: the free tier covers basic spelling and grammar, while paid plans typically add clarity, tone, style guide, snippets and team administration features. The exact boundary moves, so verify it for the month you are buying in.

A practical way to decide is to trial the free tier first, properly, for two weeks. Use it in your real email and documents, not just in a test document. At the end of two weeks, ask: did it catch errors I would have missed? Did the team actually use it, or did it sit unused? Did false flags on trade terms settle down after adding words to the dictionary? If the answer to the first two questions is yes, a paid plan is worth pricing. If the team did not use the free version, paying will not fix that; the problem is habit or setup, not features.

When you do price a paid plan, cost it per person who writes to customers, not per employee in total. A warehouse assistant who never emails customers does not need a seat. A part-time receptionist who answers enquiries all day does. Count seats honestly, and remember to factor in the time to set up the style guide and snippets. That setup time is small, but it is real, and it is what turns a subscription into a useful habit.

Also check the billing terms: monthly versus annual, how seats are added or removed, and what happens to documents or settings if you cancel. Keep a note of the renewal date. Small firms lose more money to forgotten renewals than to expensive tools.

Grammarly and UK GDPR: what actually passes through the service

Data protection is where small firms should slow down and think, because writing tools process text, and text often contains personal data.

When you use Grammarly, the text you type or paste is sent to Grammarly’s service for checking, unless you are using a version or setting that processes text locally. That means names, email addresses, phone numbers, addresses, order details and anything else in the document can pass through the service. For ordinary business writing — a quote, a marketing email, a social post — that is usually low-risk, but it is not zero-risk, and it is your responsibility to think about it.

Under UK GDPR, you need a lawful basis for processing personal data, and you need to be able to explain to customers, in broad terms, what you do with their data. If you use a third-party writing tool, that tool is processing data on your behalf. In practice, for most small firms this means three sensible steps.

First, read Grammarly’s current privacy and data processing terms before you roll it out to a team, and keep a note of what you found and when you checked. Terms change, and a note with a date is more useful than a vague memory that you checked “at some point”. If you have a privacy notice on your website, consider whether it should mention that you use writing assistance tools. You do not need to write a legal essay; a plain sentence is better than silence.

Second, set a clear internal rule: never paste sensitive client data into a writing tool blindly. That includes full bank details, passwords, medical information, legal case details, children’s personal data, and any document marked confidential. If a document contains sensitive details, redact them before checking, or check it by hand, or ask whether the writing check is even necessary. A good rule of thumb for staff is: if you would hesitate to email the text to someone outside the firm, do not run it through an external tool without thinking first.

Third, think about staff data as well as customer data. Team members’ own writing, performance notes and internal messages can also contain personal data. If you use Grammarly for internal documents, the same rule applies. Keep sensitive HR or disciplinary writing out of external tools unless you have a clear reason and a checked basis for doing so.

None of this means you should avoid Grammarly. It means you should use it with the same care you would use for any supplier that handles your words. A reputable supplier, a clear internal rule, and a dated note of what you checked will cover most small firms’ needs. If your work involves highly sensitive data — legal, medical, financial advice, or work with vulnerable people — take specific advice before using any external writing tool, rather than relying on a general guide like this one.

One more practical point: when a member of staff leaves, remove their Grammarly access promptly, just as you would remove email access. Their personal dictionary and snippets are not business assets to keep, but their access is a security loose end if left open.

Honest limits: what Grammarly will not do for you

A guide that only praises a tool is an advert, not a guide. Here are the limits that matter most for a small firm.

Grammarly will not fix a weak argument. If your proposal does not explain why you are the right firm for the job, perfect punctuation will not save it. If your price is unexplained, your timescale is unrealistic, or your scope is vague, the tool will polish the sentences that contain those problems and leave the problems untouched. Read proposals for logic and completeness separately from grammar. Ask: would this convince me, if I were the customer?

Grammarly will not check your facts. It will not know that a product was discontinued, that a price changed, that a road is closed, or that a date is a bank holiday. It may even suggest a “correction” to a correct fact because it looks like an unusual name or number. Facts need a human check against your own records, your supplier, or the customer’s brief. Never assume that because Grammarly found no errors, the document is correct.

Tone suggestions can be wrong. Grammarly might suggest a more formal tone for a customer you know well, or a more casual tone for a formal complaint. It might suggest softening a firm boundary — a payment term, a cancellation policy, a safety instruction — until it sounds like a suggestion rather than a term. Tone is context, relationship and judgement. Use suggestions as a prompt to re-read, not as a decision.

Grammarly can over-correct UK English and industry terms. Even with the language set to English (UK), it can flag local spellings, dialect words, trade abbreviations and brand names. That is why the dictionary and style guide steps matter. If your team starts to distrust suggestions because of repeated false flags, fix the dictionary rather than telling the team to ignore the tool. Ignoring a tool habitually is worse than not having it, because it trains people to miss real errors too.

AI-generated text still needs a human check, and this matters more every year. If you use an AI tool to draft a post or an email, and then run it through Grammarly, you will get a polished draft that may still contain invented facts, inappropriate claims or a tone that does not match your firm. Grammarly checks language, not truth. A human must check claims, prices, dates and promises before anything goes out under your business name. For a broader view of how AI assistants fit into a small firm’s daily work, see this guide to Microsoft Copilot for small business.

Grammarly can also make writing too uniform if used without care. If every team member accepts the same clarity suggestions, your emails may start to sound similar, which is good for consistency but can flatten personality. A café owner, a solicitor and a builder should not sound identical, and neither should two people in the same firm if they serve different customers. Keep a little individual voice. Customers buy from people, not from a style guide.

Finally, Grammarly is not a proofreader for legal or safety-critical text. Contracts, terms, safety instructions, medical information and formal notices deserve a proper human proofread, and often professional advice, regardless of what any writing tool says. Use Grammarly as a first pass, not as the final authority, for anything where a mistake could cause financial loss, legal trouble or harm.

Common mistakes small teams make with Grammarly

Most Grammarly disappointments come from a handful of avoidable mistakes.

The first is accepting everything. A team that clicks “accept all” will eventually send a message that is grammatically tidy and factually wrong, or tonally wrong for the customer. Slow down on important messages. Accept suggestions one by one, and read the sentence after each change.

The second is never adding trade words to the dictionary. The team gets annoyed by false flags, stops using the tool, and then concludes the tool does not work. Spend the first two weeks adding words. It is boring, and it transforms the experience.

The third is using snippets as scripts. A snippet that is sent unchanged to every customer will eventually sound hollow, and customers can tell. Use snippets for structure and key facts, then add a sentence that is specific to that customer. That one sentence is often what makes a reply feel human.

The fourth is forgetting the mobile and browser settings. A team member who uses Grammarly on a laptop but not on a phone will still send rushed, unchecked messages from the phone. Check each device and each browser. If someone works mainly from a phone, make sure the mobile setup is part of their onboarding.

The fifth is treating Grammarly as a substitute for training. If a team member struggles with written English, Grammarly can help them improve, but it works best alongside feedback and examples, not instead of them. Show people good examples from your own sent emails. Praise a clear quote. Explain why a revised sentence works better. Tools support learning; they do not replace it.

A simple weekly habit that makes it stick

Tools fail when they depend on willpower. Make Grammarly part of a routine instead.

On Monday, check that your style guide and snippets are still current. Has a price changed? Has an opening time changed? Has a product name changed? Update the snippets now, not when someone sends an out-of-date message.

During the week, when Grammarly flags a trade term, add it to the dictionary straight away. Do not leave it for later. Later never comes, and the same flag will annoy the next person too.

On Friday, pick one sent message — a quote, a reply, a post — and read it again. Would you change anything? Would a clearer sentence have helped? Share the example with the team if it is useful, without naming and shaming anyone. Small, regular reflection beats a one-off training session.

Once a quarter, review seats, access and settings. Who has left? Who has joined? Is the language still set to English (UK)? Are there snippets nobody uses? A fifteen-minute review every three months keeps the setup honest and avoids paying for seats nobody needs.

That habit is not exciting, but it is how small firms get value from small tools. The firms that benefit most from Grammarly are not the ones with the most expensive plan. They are the ones that set it up properly, use it daily, and keep a human in charge of the final message.

The bottom line for a small UK firm

Grammarly for small business is worth trying if your firm writes to customers every day, which most firms do. It will not write your proposals, win your customers or fix your arguments. It will catch slips, prompt clearer sentences, and help a small team sound consistent. Set it to British English, build your dictionary and snippets, agree that the sender owns the final message, and keep sensitive data out of it unless you have thought it through. Check current pricing before you budget, trial the free tier honestly, and cost paid seats only for people who write to customers.

Above all, keep the human check last. Read the message as your customer will read it. Check the facts, the numbers and the tone. Then send it, knowing that the tool helped you, but you wrote it.

FAQs

Is Grammarly worth it for a small business?

For most small firms, yes, if writing is part of daily work. It catches spelling, grammar and clarity slips in emails, quotes and customer replies before they reach a client. It does not replace judgement, proofreading or knowledge of your trade, but it raises the floor of everyday writing across a team.

Does Grammarly work in Word, Google Docs and email?

Yes. Grammarly offers a browser extension, apps for Windows and Mac, and integrations for Microsoft Word, Google Docs and common email tools. That means the same checks follow you from a proposal in Word to a reply in Gmail or Outlook. You still need to check that it is switched on for each tool you use.

Can a small team share one Grammarly account?

No, sharing one login across a team is a poor idea in practice. Each person should have their own account so their writing, dictionary and snippets stay separate, and so you can remove access cleanly when someone leaves. Paid team plans are designed for this, with an admin view for managing seats.

Is Grammarly safe for customer data under UK GDPR?

Grammarly processes the text you run through it, so you should treat it as a processor of whatever you paste or type. Avoid putting sensitive client details, passwords, medical information or unredacted personal data into it unless you have checked its current privacy terms and your own lawful basis. For ordinary business writing, keep a simple rule: if you would not email it to a stranger, do not run it through a writing tool blindly.

Will Grammarly fix my writing completely?

No, and that expectation causes most disappointment. It is strong on spelling, punctuation, clarity and tone, but it cannot tell whether your price is right, your facts are correct or your argument makes sense. A confident, well-punctuated email can still be wrong, so a human check on facts and meaning always comes last.

Does Grammarly understand UK English?

Yes, you can set it to British English, which helps with spellings like organise, colour and behaviour. It can still over-correct trade terms, place names and brand spellings it does not recognise. Adding those words to your personal dictionary and team style guide solves most of this over time.
