Acorny
Your highlights fade. Acorny makes them stick.·acorny.io
Acorny captures highlights from webpages, Kindle, PDFs, and other reading tools, then turns them into active recall cards using cloze deletion or Q&A formats. It schedules reviews with a spaced repetition system based on the SM-2 algorithm, and sends a daily digest of highlights due for review. Users can import existing highlights from tools like Readwise, Instapaper, Cubox, and Diigo, and export their data at any time.
