What is an AI essay checker?
An AI essay checker is a tool that reviews written essays for grammar, clarity, structure, and argument strength, then returns specific suggestions and an improved version of the text. It works like an automated writing tutor, identifying issues a writer might miss on their own.

Yes. It reviews grammar and mechanics, clarity and word choice, structure and organization, thesis strength, argumentation, and transitions, then classifies each issue by type and severity.
Can I upload a file instead of pasting my essay?
Yes. You can upload a PDF, DOC, DOCX, ODT, TXT, MD, or HTML file up to 2MB, and the tool will automatically extract the text. If you’ve already typed or pasted text into the box, the extracted file text is added alongside it rather than replacing it.
Is my essay score based on the original or the edited text?
Your score reflects the original essay you submitted, before any AI suggestions are applied. This gives you an honest baseline. The improved essay is provided separately so you can compare it against your original score.
