How it works

How to check your grammar

The grammar checker reads your text as you type. You decide which fixes go in.

  1. Paste or type your text

    One sentence or a full draft. The check starts a moment after you stop typing.

  2. Read the issue list

    Each issue is underlined in your text and listed under its category. Pick a category above the list to clear one kind at a time.

  3. Fix or dismiss

    Click a suggestion to apply it, or use Fix all for a whole category. Dismiss drops a single flag. Ignore word leaves a name you spelled on purpose alone.

  4. Read it once more

    Press Check again and read the changed sentences aloud. A correct sentence can still say the wrong thing.

What it catches

Spelling, grammar and punctuation in one check

The small mistakes that make a reader stop and reread, each one labeled with its reason.

Spelling

It works as a spell checker for typos like “recieve”. It also notices whether your text uses American or British spelling, so “colour” in a report for a London client stays put.

Grammar and verb forms

Wrong verb forms, missing words, and “a” where “an” belongs.

Subject and verb agreement

The usual slip has a long phrase between the two: “The list of open tickets are long.” The subject is “list”, so the verb is “is”.

Punctuation

Missing or misplaced commas, and two sentences glued together with one.

Word choice

Mix-ups like “affect” and “effect”. If the whole sentence needs new wording, try the paraphraser.

Typography and capitalization

Lowercase day names and doubled spaces, the slips that pile up when you paste between documents.

What you get

Free grammar checks, plus clarity if you want it

Style rules in the free check

The free check includes rule-based style flags for redundant words and phrases. Fixed rules mean the same text gets the same flags.

Clarity suggestions on paid plans

Paid plans add a language model pass that points out wordy or vague phrasing and offers a tighter version. Clarity checks a day: 20 on Basic, 30 on Plus and 40 on Pro. A suggestion that would change a figure or a name is dropped before you see it.

A history of your checks

When you're signed in, each check is saved with your text and its issues for up to one year. Delete any entry whenever you like.

Example

One email, three fixes

Before

Thanks, we recieve the signed contract on monday, but pages four and five was missing.

After the fixes

Thanks, we received the signed contract on Monday, but pages four and five were missing.

A client email with three slips. Two are in the verbs, one is a day name.

Commas and periods

A punctuation checker for the marks that matter

Most punctuation trouble comes down to where one thought ends and the next begins. The punctuation checker flags those spots. Pick Punctuation above the issue list to clear them first.

Take a line from a work email: “The slides are attached, let me know if anything is missing.” That's two sentences joined by a comma, a comma splice. Split it with a period, or join the halves with “and”.

A colon needs a full sentence before it: “Bring your badge and laptop: the room has no spares.” On the comma before “and” in a list, the checker doesn't push you either way. Pick one habit and keep it.

Before you submit

Checking an essay before you hand it in

Proofread last. Settle the argument and the order of your paragraphs first, because a fix on a sentence you later cut is wasted time.

Slow down where your evidence meets your reading of it. Keep pronouns close to their nouns and stay in one tense. If a word inside a quotation gets flagged, leave it. A quote stays as its author wrote it.

Clean grammar won't fix a missing citation, so review your sources separately. To see how the draft reads to an AI detector, Textlume has an AI detector that gives a likely range and a confidence rating.

Pick the right tool

Grammar checker or paraphraser?

A grammar checker fixes the sentence you have. A paraphraser gives you a new one.

Who uses it

Check what you're about to send

A college application essay

A typo in the opening line is the last thing an admissions reader should see. Run a check after each round of feedback.

An email to your manager or a client

A quick pass catches the missing word in a request and a deadline typed as “Thrusday”.

A blog draft on deadline

Clear the flags fast and spend the time on the headline. The word counter keeps you on length.

A cover letter

Make sure job titles and company names are spelled the same way every time.

Writing in your second language

An engineer from Brazil or a grad student from Korea can catch article and preposition errors in English. Keep the fixes that match what you meant.

Help articles and product copy

Check that each step starts with an action and that product terms are spelled one way throughout.

FAQ

Common questions about this tool

Contact
How can I check if my sentence is correct?

Paste it into Textlume and the check runs by itself. Each flag names the problem and offers a fix. Read the fix inside your sentence before you accept it, since a correct change can still shift your meaning.

Can I ask an AI chatbot to fix my grammar instead?

You can, and you'll get a corrected version back. A chatbot tends to rewrite more than you asked, though, and won't list what it changed. Textlume flags each issue in place, so you see every change and keep your own wording.

Isn't the checker in my word processor enough?

For a quick draft it often is. A separate checker helps when you want every issue listed by category, or when you write somewhere with no built-in check, like an application portal. Paste the text into Textlume, fix it and copy it back.

How do I know if a grammar checker is accurate?

Test it on mistakes you know the answer to. Write a sentence with a misspelling and a verb that disagrees with its subject, then see what Textlume catches and whether the fixes are right. Watch for false flags on names and technical terms too.

What's the difference between grammar checks and clarity suggestions?

Grammar checks follow fixed language rules and catch errors. Clarity suggestions come from a language model and target sentences that are correct but wordy or vague. Grammar checks on Textlume are free. Clarity comes with paid plans, with a set number a day.

Which languages does the grammar checker support?

Textlume checks grammar in English, German, Spanish, French, Italian, Dutch, Portuguese, Polish, Russian and Arabic. Turkish isn't covered. The checker reads the language from your text, and you can change it in the editor. For English it also tells American from British spelling.

Do I need an account to check grammar?

No. Grammar checks run without signing up, and no plan limits how many you run. The one exception is an abuse guard of 500 checks per IP address a day. A free account adds history. Clarity suggestions need a paid plan.

Is this an AI grammar checker?

Partly. The spelling and grammar check runs on an open-source grammar engine that we host ourselves, and nothing changes without your click. On paid plans an AI clarity pass sits on top. It drops any suggestion that would alter a number, a name or a quotation.

Is my text saved when I check grammar?

If you aren't signed in, nothing is saved. Signed in, the text and its issues go into your history, where you can delete one entry or all of them. Text sent for clarity suggestions goes to an AI service that may not keep it or train on it.

Can I check a whole essay or long report at once?

Yes, up to 20,000 words at a time. A long text is checked in parts, with a progress line while they come back. If a part doesn't come back in time, it's shaded, and Check again retries it.

Run a grammar check before you send it

Paste the final version and clear the flags before it goes out.
