AI Study Sheet turns the materials you already use into active-recall practice on iPhone and iPad. Import textbook photos, worksheets, class notes or PDFs, then recall hidden terms before revealing the answers. There is no need to rebuild your materials as flashcards.

AI identifies study terms and creates masks as a starting point. Adjust its selection, add masks manually or combine neighboring terms by dragging. Review in order, randomly or with a focus on weak points.

Version 3.0 removes the fixed 20-page PDF limit. Pages are processed individually, so ready pages can be studied while the rest continue processing; imports can be paused, resumed and retried. Folders, search, study history and backup help organize ongoing revision.

Materials are processed on device and are not uploaded to external AI services or Toybird Labs servers. No account is required.

Freemium: start with 3 saved pages, then permanently unlock 10 free saved pages after your first study session. Unlimited Saves is an optional US $4.99 one-time purchase. No subscription. Requires iOS 16 or iPadOS 16 or later.
