Fixes, not a rewrite

Free Grammar Checker

Find grammar mistakes, spelling errors, punctuation problems, and awkward sentences. Each note explains the change, and the corrected copy stays as close to your wording as the fix allows.

How it works

  1. 01

    Paste the draft

    The checker looks for agreement, tense, word choice, punctuation, and sentences that are hard to follow.

  2. 02

    Review the notes

    Every issue is labeled grammar, spelling, punctuation, or awkward, with the original span and a suggested fix.

  3. 03

    Copy the corrected text

    Use the corrected version as a clean base. If you also want the prose to sound more natural in a specific field, Enhanced mode in the humanizer is the separate step.

When to use it

A last pass before submission

Catch agreement and punctuation after the argument is already in place, so you are not editing structure and commas at the same time.

Email and report cleanup

Fix there/their, its/it’s, and missing commas before a note goes to a client or a supervisor.

Writers who want the reason

The note under each issue is there so the next draft does not repeat the same pattern.

Limits and accuracy

  • Suggestions can be wrong when the sentence is technical, quoted, or intentionally informal. You accept each change.
  • The checker does not fact-check, and it does not rewrite for a discipline.
  • Awkward-sentence notes are judgment calls about clarity, not grammar rules.
  • Text is sent to a model for the check. Nothing is saved to an account.

Examples

Agreement and spelling

“The charts was missing several data point” should surface as agreement and a plural. “Loose the contract” should surface as the spelling of lose.

A sentence that is grammatical and still clumsy

A long chain of which-clauses can be flagged as awkward even when every comma is legal. The suggestion should simplify the sentence, not replace the point.
