Save it when you find it
Personal use starts with an account and your own content. Once saved, you can practice now, come back later or just keep the content.
PRODUCT / FEYNOTE
From “I understand it”
to explaining and applying it.
For people who already have something they want to remember. No career selection or complete study plan required.
Try a free example ↗Try when you are ready
Confirm the scope and answer in your own words. References stay hidden until your first attempt. Not remembering is also a valid attempt.
Compare, then try a new example
Compare your answer with the source, add a key condition and try a new situation. You can finish at any time and continue later.
Evidence for understanding. Boundaries for records.
Original content retains its source, AI notes identify their evidence, and changes to your notes require your approval. Immediate and cross-day performance are recorded separately. Saved-item counts and invented scores do not represent mastery.
What you can try today
This website offers a text example: independent answer → reference comparison → new situation → finish. It does not call AI, create an account, upload answers or create personal learning records.
Personal content import, AI feedback, cross-day practice and reminders are part of the product flow; availability depends on the actual version. This website does not claim support for every content platform or complete video extraction.
Ask about access and availability →Frequently asked questions
Do I have to practice as soon as I save something?
No. Saving and practicing are separate. Start when you want to.
Will the public example grade my answer?
No. It shows written references and comparison questions for you to check yourself. Real AI feedback is available only in product versions that support it.
Can I register or download the app here?
There is currently no public registration or download link. You can complete the website example or contact us about personal access.
Can I question an AI assessment?
The product design requires assessments to retain the source and your answer and lets you raise objections. Insufficient evidence must not be treated as a zero score.
