Comparison · Knowt
Knowt popularised free AI flashcards. Brainfy matches that — AI cards from your notes, PDFs, and photos — and adds a real spaced-repetition engine, a Pomodoro timer, and a weekly planner, with no ads and nothing locked behind a region.

Knowt has a large, established community library of shared notes and sets, and a polished note-taking side built up over years. If you want a big public catalogue to browse, that depth is real. Brainfy has shared community decks too, but its library is younger — so it leans on letting you import what you already have (CSV, TSV, Anki plain text, Quizlet exports) and build the rest with AI.
Yes — free during beta with no deck caps and no ads. AI card generation, the study modes, and spaced repetition are all included.
Yes. Export your set as text or CSV, then paste or upload it in any deck Cards tab — Brainfy auto-detects the separator. Anki plain-text and Quizlet exports work too.
Yes — a full SM-2-style scheduler with a four-button rating and a daily new-card cap, so you review only what is due each day.
A genuine spaced-repetition engine, a built-in Pomodoro focus timer with session logging, a weekly study planner, a focus-aware coach, and a Cloze study mode — all free.
Yes. It is a web app with no region gating, so it works in any browser worldwide.
