Start with a sentence

How can I check if my sentence is correct?

Paste your sentence, review the issues and choose the corrections that fit your meaning.

  1. Type or paste your text

    Put your sentence or draft into the editor. Grammar checks automatically, so you can start reviewing as you write.

  2. Read the Issues list

    Review the entries under “Issues”. Use “Show issues by category” to focus on one kind of correction at a time.

  3. Choose which changes to make

    Apply the corrections you want. “Fix all” applies the first suggestion to all open issues or the selected category. Use “Dismiss” to set aside an issue, or “Ignore word” to exclude a word from this and later checks.

  4. Review your edited sentence

    Use “Check again” after editing. Read the updated sentence as a whole to make sure the wording expresses what you mean.

Mistakes worth catching

Spelling, punctuation and style in one pass

Use the feedback to find small errors that interrupt a reader. These are the kinds of details to review before you share a draft.

Spelling and capitalization

Find misspelled words and capitalization issues (capitalization is listed under typography), then compare the proposed spelling with the word you intended. Give particular attention to headings, opening sentences and words you have edited several times while drafting.

Grammar and verb forms

Review grammatical errors in the sentence around them. When you change a verb, read the surrounding passage to confirm that its tense still matches when the event happened and how you describe related events.

Subject and verb agreement

Check whether the verb fits the subject, especially when a long phrase separates them. In the example below, “the results were” fits the plural subject. Finding the subject first makes the correction easier to understand.

Punctuation

Review punctuation issues with the whole sentence in view. A correction should help readers see where a thought ends, how clauses connect and which words belong together, rather than simply adding another mark.

Word choice

Check word-choice suggestions against your intended meaning. Similar-looking words can express different ideas, so read the replacement in context. Keep technical terms precise and choose wording that suits the reader and the subject.

Typography and spacing

Catch typography issues that make a finished draft look uneven. Review spacing and related details after larger edits, particularly when you have moved phrases or copied material between documents during the writing process.

What you get

A grammar pass, optional polish and saved feedback

Rule-based style checks

The automatic grammar pass includes rule-based style checks. These follow language rules, distinct from the extra model suggestions available on paid plans. Review this feedback as part of proofreading before moving on to broader changes in phrasing.

A separate style and clarity pass

Basic, Plus and Pro add model suggestions for clearer phrasing. Model suggestions a day: none on Free, 20 on Basic, 30 on Plus and 40 on Pro. These daily limits apply to the extra model pass only.

History that keeps the original feedback

For every signed-in account, history stores your input text and the issues found for a year, rather than the corrected text. That record lets you revisit the original draft and review the feedback it received.

Worked example

What an explained fix changes

Before

The team recieve the report on monday but the results was unclear.

After, fixes applied

The team received the report on Monday but the results were unclear.

Each fix in the real tool comes with its category named. Spelling, capitalization and one grammar catch, all explained before you apply anything.

Sentence boundaries

Use a punctuation checker to make your meaning clear

Punctuation tells readers how to group your words. Start by identifying the complete thoughts in a sentence, then review the marks between them. This approach helps you understand a proposed correction instead of treating every comma as a pause. Use “Show issues by category” to focus your review on punctuation while leaving other edits for later.

Consider this draft: “The figures are ready, please review them.” Both parts can stand as sentences, so a full stop gives a clear correction: “The figures are ready. Please review them.” A semicolon also connects the closely related thoughts: “The figures are ready; please review them.” Choose the version that fits the pace and tone of your message.

A colon serves a different purpose: it introduces an explanation, example or list after a complete clause. For example, “Please bring the following items: a notebook, a pen and your notes.” After changing punctuation, read the sentence aloud and check its structure. Clear boundaries help readers follow instructions without rereading them.

Before submission

Use an essay checker before you hand it in

Finish the argument and paragraph order before your final proofreading pass. Once the structure is settled, work through the introduction, body and conclusion in manageable sections. Keep each paragraph's main claim in view as you review its sentences. This helps you correct the language while preserving the point you want the paragraph to make.

Pay special attention to sentences that combine evidence with your interpretation. Make the source of each claim clear, keep pronouns close to the nouns they refer to and use a consistent tense when discussing a text or event. After editing a quotation's surrounding sentence, compare the quotation with its source and keep the quoted wording exact.

Separate proofreading from source review. Check that borrowed ideas have citations, that references match your required format and that each piece of evidence supports your claim. For a separate review of writing patterns, Blurwrite's AI detector provides a reading with a confidence rating. Keep that task distinct from correcting the language and reviewing the evidence in your essay.

Questions

Questions about this tool

How can I check if my sentence is correct?

Paste the sentence into Blurwrite and review the issues it finds. Read each suggestion alongside your sentence, then decide whether the change fits your meaning. After editing, use “Check again” to review the new wording. This gives you a practical way to check a sentence before you send or submit it.

Can a conversational AI tool check grammar?

Yes, ChatGPT can suggest grammar corrections when you ask it to proofread a sentence. Give it a clear instruction to explain the proposed edits. For a focused editing workflow, paste the same sentence into Blurwrite and work through the issue list before revising the rest of your draft.

Can a document editor check grammar?

Yes, Google Docs offers spelling and grammar suggestions for supported languages. You can use that feedback while drafting a document. To review a passage with Blurwrite, copy it into the grammar checker and work through the identified issues, then use the edited wording in your document.

Which grammar checker is most accurate?

The most accurate grammar checker for you correctly fixes errors in the kinds of writing you use. Test an agreement error, a misspelling and a punctuation problem whose corrections you know. Use Blurwrite to inspect the suggestions in context, checking both the correction and whether the sentence still expresses your intended meaning.

What is the difference between grammar checks and style suggestions?

Grammar checks address language rules, while the separate model pass suggests changes to style and clarity. Blurwrite's grammar pass also includes rule-based style checks. Basic, Plus and Pro add model suggestions for phrasing, such as wordy expressions or vague wording, so you can polish a draft after dealing with its errors.

Which languages does the grammar checker support?

Blurwrite's grammar checker supports exactly ten languages: English, German, Spanish, French, Italian, Dutch, Portuguese (Brazil and Portugal), Polish, Russian and Arabic. To check a sentence in one of these languages, paste it into the editor and review the feedback against the wording you intended. You can start with a short passage before reviewing a longer draft.

Do I need an account to check grammar?

You can run grammar checks without creating an account. The grammar check is free and unlimited on every plan, so you can check another draft or review the same passage after editing. Start by pasting your text into the tool and use the feedback to guide your next edit.
