How it works
Three seconds from paste to play
01
Paste
Notes, an article, a whole chapter. SuperGuide reads it and pulls out the atomic facts: the terms, numbers, dates and ideas actually worth keeping.
02
Play
The first question appears before you finish reaching for your coffee. Multiple choice, cloze, match, order: games are just different views over the same facts.
03
Keep
FSRS spaced repetition schedules each fact to come back the day you would otherwise lose it. Two minutes a day, and it stays.

Questions, answered
Frequently asked
How do I memorise anything I read?
Stop rereading and start retrieving. Paste the text into SuperGuide: it extracts the facts, asks you them as short games, and then asks again right before you would forget. Being asked is what makes memory stick; rereading only makes text familiar.
What is spaced repetition?
A review schedule that re-asks each fact just before your brain lets it go, so every review lands at the moment it helps most. SuperGuide uses FSRS, a modern open algorithm, to time those reviews per fact, per person.
What can I paste into SuperGuide?
Anything that is text: lecture notes, an article, a chapter, a recipe, meeting notes, a Wikipedia rabbit hole. The free plan takes up to 50,000 characters per paste, roughly a long book chapter. URL, PDF and photo import are on the way.
Is SuperGuide free?
Yes. Free includes 3 decks a day, 50,000 characters per paste, every game and full spaced repetition. Plus adds unlimited decks, 200,000 characters, enriched decks, covers and streak freeze. The demo on this page is free with no sign-up at all.
How is this different from flashcard apps?
You never write a card. SuperGuide extracts the facts for you, writes wrong answers plausible enough to catch bluffing, and plays the same fact through different games so recognition cannot masquerade as knowledge. The schedule is FSRS, the same science serious flashcard nerds swear by, minus the homework.
When can I get the app?
SuperGuide is launching soon on iOS and Android. Until then, the demo on this page makes a real 5-fact deck from anything you paste, and every deck on our learn pages is playable in the browser.
