Pricing

Free for students.
Fair for everyone else.

A student never pays. Developers build for free and pay only at scale. Institutions pay per learner for the classroom tools, roster sync, and support. No student data is ever sold, on any plan.

Cognivia is an independent, open research project. The protocol, analysis, and trial data are public. Any paid tier funds the work; it never puts a student behind a paywall.

Pricing questions

Straight answers.

Is it really free for students?
Yes, and deliberately free for low-income learners. Any future paid tier is for institutions, never for a student.
What counts as an active learner?
A learner who answered at least one question in the billing month. Dormant accounts are not billed, so a class of forty that meets weekly is not a class of forty every day.
Do you sell or advertise on student data?
Never, on any plan. Records are pseudonymised, access-controlled, and used only to run the diagnostic. Under-18 data is not processed without verifiable guardian consent.
Can I try the API before paying?
Yes. The demo key works immediately on the stateless endpoints, and a self-serve live key from the console is free to start. See the quickstart.
What if the research finds a null result?
The diagnostic and the Cognitive Passport are useful on their own, whatever the scheduling trial concludes. The measurement layer stands regardless, and the data stays public.
