For educators

Check student writing for AI.

Paste a submission and get an AI result in plain English. Use it alongside your own review, the student’s drafts and a conversation about their work.

Check for AI →How it works

Get a clear result

See whether the text looks human-written, is hard to classify, or looks AI-written. Open the details when you need the model information and measurements.

Understand the limits

AI detectors can make mistakes. Nota requires at least 10 words, and results under 50 words are often wrong. Long submissions may be checked only in part. Published error rates apply to the test sets described in the result.

Decide what to review next

A result can help you decide what to discuss. Ask about sources, drafts and the assignment’s AI policy before drawing conclusions about a student’s work.

Tools for your review.

Batch checks

Review up to 10 files at once on Individual or 100 on Professional. Each file gets its own result.

Saved reports

Individual and Professional let you download and share an AI-check report tied to the text you checked, with its result and limitations.

Optional writing history

Students can share a free report of the history or file details available in their document. History can be incomplete, and file metadata can be edited; neither proves who wrote the text.

Find matching sources

Paid plans include source matching in beta. Compare selected passages with web and scholarly sources to help review citations and overlap.

Questions about Nota

Learn more about how it works.

Can a Nota score prove misconduct?No. AI detectors can make mistakes, and a result does not establish who wrote something or whether an assignment policy was broken. Review it alongside drafts, sources and the student’s explanation.

What about non-native English writers?We have not published a separate false-positive evaluation for non-native English writing. The general error rate should not be treated as a measured rate for that group.

Do you integrate with Canvas or other LMS?LMS integrations are not available yet. You can check pasted text or upload files directly.

Which plan can I use?Free includes 2,000 words a day. Individual adds saved-report downloads, sharing, source checks and batches of up to 10 files. Professional supports batches of up to 100 files and API access.

How is student text handled?Text is sent to the services needed to run the checks. Source checks temporarily store text while processing. You choose whether to include text in a saved report. Review the privacy policy and your institution’s requirements before submitting student work.
