Toolglade’s take
A genuinely privacy-forward active-recall app: on-device processing, no account, and a one-time $4.99 unlock instead of a subscription. The free tier is quite limited (3 saves, growing to 10 after a first study session), and it is iOS/iPadOS-only with the best document recognition reserved for iOS 26+.

About AI Study Sheet
An iOS/iPad app whose on-device AI masks key terms on your own photos and PDFs for active-recall review, with a one-time $4.99 unlock.
AI Study Sheet (by Toybird Labs) is an iPhone and iPad app for active-recall study from materials you already have. You import photos, textbook pages, notes, or PDFs, and the app's on-device AI reads the text, identifies likely key terms, and overlays masks on the original page layout rather than making you rebuild flashcards. Review sessions can launch straight from a reminder notification when pages are due. The vendor highlights that materials, recognized text, key terms, and saved data are processed on-device and not uploaded to external AI services or Toybird Labs servers, with no account required. It supports adjustable term density and a pre-marked-material mode, and requires iOS/iPadOS 16+.
