AI Red Sheet - Auto-mask important terms just by taking a photo app

This is an iPhone and iPad app that lets you import photos or PDFs of textbooks, handouts, and notes, and turn them into memorization tests while preserving the original layout.

The AI selects important terms and hides them, allowing you to recall the answer and tap to verify it. You can add or delete hidden terms, or select terms yourself. While maintaining the positional relationship with diagrams and tables, you can use it for reviewing school tests, qualification exams, and language learning.

Teaching material images and recognized text are processed on the device and are not sent to external AI services or Toybird Labs servers. No app account registration is required.

The free storage limit is 3 images initially, and 10 images after your first study session. You can unlock unlimited storage with a one-time purchase of 800 yen. There are no subscriptions.
