Butterfast — AI Presentations

A single source produces flashcards, a multiple-choice quiz, study notes, a mind map, and an audio lesson, and because the AI reads your source first and then decides what belongs in each output format, you end up with material that stays consistent across all five instead of five loose piles of text. You don't pick one output and wait; you get the whole set at once. Big time saver. For a busy student, that's the difference between studying and formatting. That matters more than it sounds.

Butterfast reads PDFs, YouTube videos, audio files in MP3 and WAV, and pasted text, and when you hand it a long recording or a dense chapter, the AI pulls out the concepts that matter and skips the filler so you get a usable set of cards instead of a raw transcript. There's no manual card entry, which is the part most people quit over. If your habit is PDF to study notes, or YouTube to flashcards, this step does the work for you.

Each flashcard carries a level and a next-review date. Cards you miss come back sooner, while ones you know get spaced out. That schedule turns plain spaced repetition flashcards into something you actually remember weeks later. It's the part most card generators skip.

The app tracks experience points across a 20-level system and rewards streaks, and you earn that XP for the routine acts of writing notes, finishing quizzes, and reviewing flashcards. It sounds gimmicky at first. Then you notice you're opening the app on a Tuesday night you'd otherwise skip.

Beyond cards, Butterfast builds concept maps that show how ideas connect, plus audio versions of your notes that you can play while your attention is somewhere else. The audio mode is handy when you can't look at a screen, like driving or walking between classes. Hands-free review, done.

Everything runs in the browser. That means no app store, no disk space, and the same deck on your phone and laptop as long as you log in. One catch: you need an internet connection to study.
