What Memreader is
Memreader is a browser reading app that turns passages from uploaded books and papers into flashcards for spaced-repetition study. It accepts EPUB, PDF, and DOCX files; readers can highlight sentences in EPUBs and PDFs, then press N on a passage to create a card with that passage as the answer. Reviews use an FSRS schedule that adapts to recall performance. Reading controls include nine typefaces, five text widths, and light and dark modes, and the app requires no installation. Its free plan has no expiry and allows up to three books, unlimited highlights on those books, and 50 active flashcards. Pro is listed at $8 a month or $72 a year, adding unlimited books and cards, cross-device sync, Anki export, an activity heatmap and review dashboard, and priority support. Users retain rights to their uploaded books, highlights, notes, and cards. Memreader says data is encrypted in transit and at rest, and that it does not sell user data or use advertising trackers; basic server logs are retained for up to 30 days.
