Free to try. Pay for Nota words.
Nota is a full model forward pass, so words are what we meter. The evidence panel comes with every scan on every plan. Prices are a starting offer; plan names are fixed.

Developer: prepaid credits, Nota words rounded up to 100, Bearer keys. Teams (seats, shared quota) later — no LMS.
The same caveats, whatever you pay.
- Scores are probabilistic and specific to this model version.
- Below 250 words Nota abstains rather than guess.
- The false-positive rate shown is the one measured for the shipped checkpoint on held-out human writing of 250 words or more — it comes from the API, never from a marketing page.
- A low score is not proof a person wrote this. It means this model did not flag it.
- Nota does not name a generator, does not highlight sentences, and scores documents whole.
Teams and institutions
Seats and shared quota come later. Nota is not sold as a classroom accusation tool: no published ESL false-positive rate exists yet, so we do not claim one.
