Essay Grader for Chrome
Paste your essay or select it on the page. In about ten seconds you get a score out of 100, a letter grade, five criteria with comments and a short list of fixes. The extension never rewrites your text: you make the changes, and the writing stays yours.

What this essay grader looks at
Without a rubric, every essay is graded on five criteria, each out of 10: thesis and argument, organization, evidence and support, style and clarity, grammar and mechanics. Each criterion gets a short comment about your essay. If you add the assignment prompt, the grade checks whether the essay answers it. If you paste a rubric, the grade follows its criteria and weights instead.
The score is an estimate from an AI model, not your teacher's mark. Use it before you hand a paper in, to find the weak paragraph and fix it yourself. Two grades a day are included at no cost, and there is no account to create.
What it does not do
It is not an AI detector and not a plagiarism checker, and it does not guess who wrote the text. It does not write or rewrite paragraphs for you. Google Docs does not share its selection with extensions, so there you copy the text and paste it into the window.
Questions
Is the score the grade my teacher will give?
No. It is an estimate from an AI model, based on a standard essay rubric or the one you paste. Treat the number as a signal and the comments as the real value.
Does it rewrite my essay?
No. A comment quotes at most one short phrase and explains the fix. The rewriting is yours.
Do you store my essay?
No. Our server grades the text and discards it, keeping only a daily counter for a random install ID. In Chrome the text stays in session memory while it is being graded and is never written to disk.
