How does an essay checker work
The first pass on any essay is the clean-up. Paste your draft and the checker reads it line by line for the mistakes that cost you easy marks:
- Spelling and typos
- Punctuation you missed or overused
- Capitalization slips
- Grammar : tense, agreement, run-ons, fragments
- Clarity : sentences that say less than you meant
It is the fastest way to stop losing points to small errors. Fix them here before sending your teacher the draft.

Check for AIFrequently Asked Questions
Your essay, your grade, and what happens to your draft, answered.
Is the essay checker free?
Yes. You can check your essay and see the grammar fixes with no sign-up. The first grades on the rubric are free too, and the free limit is there to keep the tool open for everyone, not to push you toward a paywall.
Does it check grammar and spelling too?
Yes. The grammar check is the first thing it does: spelling, punctuation, capitalization, grammar, and clarity, all flagged instantly so you can clean up the draft before you submit.
Can the essay checker grade my essay or give it a score?
Yes. Past the grammar clean-up, CoGrader scores your essay against a real rubric and returns the mark it would get, a breakdown by criterion, and the one change to make first. A plain corrector stops at the typos; this tells you the score.
What is the difference between an essay checker and an AI checker?
An essay checker fixes your writing and scores it. An AI checker answers a different question: whether an essay was written by AI. If that is what you need, use the AI essay checker instead.
What rubric does it check my essay against?
It auto-detects the rubric that fits what you wrote, then scores each criterion separately. You can also pick AP English, a state writing rubric like STAAR, FAST, Regents, or CAASPP, or paste the one your teacher gave you.
Is my essay stored or used to train AI?
No. Your essay is sent to the model for the check and dropped after the result comes back. It is not stored, shared, sold to advertisers, or used to train anything.
How accurate is it compared to a teacher?
It scores against the same rubrics teachers use, so the criteria line up. It will not match your teacher exactly, no automated score does, so treat it as a revision signal, not the final word, and lean on the criterion breakdown over the total.
