What does the essay checker check?

Two layers: mechanics (grammar, spelling, punctuation — corrected automatically) and substance (thesis strength, paragraph structure, transitions, clarity — covered in the Feedback mode with specific, actionable notes).

Will it rewrite my essay for me?

No — and that's deliberate. Corrections fix errors while preserving your argument and voice; feedback tells you what to improve and why, but the revision is yours. That keeps the work honest and the learning real.

Can I use it for college application essays?

Yes — the Feedback mode works well for personal statements, where voice matters more than formality. Use Fix errors sparingly on such essays and re-read every change: your natural phrasing is part of the story.

Is the essay checker free?

Yes — free with no sign-up, up to 50,000 characters, all three modes included.

Free AI Essay Checker

More than a grammar pass: correct every mechanical error in your essay and get honest feedback on thesis, structure and flow — before your grader does.

About this essay checker

An essay can be grammatically spotless and still earn a C. Graders mark theses that don't commit, paragraphs that wander, and conclusions that just restate the introduction. This free essay checker covers both layers: it corrects every mechanical error, and — in Feedback mode — reviews your essay the way an instructor would, from thesis to transitions.

The feedback is structured to be usable: specific notes under Thesis & argument, Structure & flow, Clarity & style and Grammar & mechanics, ending with the top three improvements ranked by impact on your grade. No vague “add more detail” — you get told which paragraph, and why.

It's honest by design: the checker fixes errors but never writes your essay. Draft, get feedback, revise, run the final Fix errors pass — that workflow produces better essays and better writers. For sentence-level polish along the way, the sentence rewriter and comma checker are one click away.
