Turn materials into review sheets
Use a camera photo or an imported image. The app recognizes text on the page and automatically selects words or phrases to cover with memory masks.
iPhone study-material masking app
AI Memorize Sheet
Take or import a study-material photo, let the app find important terms, and review the page with tap-to-reveal memory masks.
Choose the masking level
Select 5%, 10%, 20%, or 30% depending on how hard you want the review session to be. Tap a mask to reveal the original text underneath.
Save and organize pages
Save created sheets, edit titles and notes, organize pages into folders, and start review sessions from your library.
Built for students, exams, language learning, and everyday review
Study from what you already have
Works with textbooks, handouts, notes, reference pages, worksheets, and other study materials that can be photographed or imported.
On-device processing
OCR, candidate selection, saved pages, folders, and settings are handled on your device. The app does not upload your study images to Toybird Labs servers.
Multilingual interface
The app supports major interface languages and follows the system language by default. You can also change the display language in the app settings.
Free to start
You can save up to three study pages for free. Free users can replace saved pages when they want to try new materials.
One-time upgrade
The optional Unlimited Saves purchase unlocks unlimited saved pages. Pricing is shown in the App Store before purchase.
Accuracy depends on the source
OCR and automatic selection work best with clear, well-lit printed text. Handwriting, blur, shadows, complex layouts, and low-resolution images may reduce accuracy.
Privacy-conscious by design
No account is required, and the app does not use a developer-operated server to store your study materials.
Photos and imported images are used to create local study sheets. The app does not send your study images or extracted text to Toybird Labs servers.
System Requirements
iPhone with iOS 26 or later.
