What Memreader is

Memreader is a browser-based reading app for turning books and papers into flashcards for spaced-repetition study. Upload EPUB, PDF, or DOCX files, then highlight sentences in EPUBs and PDFs. Press N while viewing a passage to make a flashcard with that passage entered as the answer. Cards use an FSRS review schedule that adapts to recall performance, and flashcards are the listed study mode. The reader has nine typefaces, five text widths, and light and dark modes. It runs in any browser and requires no installation. The free plan has no expiry and supports up to three books, unlimited highlights on those books, and 50 active flashcards. Pro is available for $8 a month or $72 a year, with unlimited books and flashcards, cross-device sync, Anki export, an activity heatmap and review dashboard, and priority support. A Founding Member plan costs $49 a year and includes Pro features, roadmap input, direct founder access on Discord, and a profile badge. Memreader is released under AGPL-3.0. Users retain rights to their uploaded books, highlights, notes, and flashcards; they can export flashcards as Anki decks.
