Your writing

Choose a file PDF, Word or photo. Up to 8 pages.

Reading your document

This usually takes 20 to 60 seconds. Keep this page open.

Your paper is back.

We don't keep a copy of your writing.

Your file is opened in your browser. Only its text is sent to Anthropic's Claude API to be graded, and the graded pages are drawn in your browser.

Nothing is saved on our side: not your writing, the comments or the grade. When you leave the page, it's gone, so download anything you want to keep. Anthropic doesn't use API data to train its models by default.

To improve the app, we count visits and which buttons get used (anonymously, with no cookies), never anything from your document.

Don't upload anything you aren't allowed to share, like other people's private information.
