Read once.Play daily.Remember.
Paste anything worth remembering. Three seconds later it is five facts and a game. Then spaced repetition, run by FSRS, asks each fact back the day before you would have lost it.

How it works
From paste to permanent, in three moves
Paste
Anything you want to keep: notes, an article, a chapter, a rabbit hole. SuperGuide reads it and pulls out the facts worth remembering, in about three seconds.
Play
Multiple choice, cloze, match, order, speed rounds. Same facts, different games, so recognising an answer never gets mistaken for knowing it.
Remember
FSRS learns how fast each fact fades for you and asks again the day before it goes. Miss it, it comes back sooner. Nail it, the gaps stretch to months.

The science
Your brain forgets on a schedule. So we ask on one.
Every fact starts fading the moment you close the tab. Ask it back right before it goes and it comes back stronger, and the next gap can be longer. That is spaced repetition. SuperGuide runs it with FSRS, an open algorithm that learns how fast each fact fades for you, then re-asks it a day early.
It is brain training on things you actually want to know: your notes, your reading, your job. The exercise is retrieval, the one that builds memory. The timing makes two minutes count.

Daily, not someday
Fast enough to play in a queue
A memory habit survives only if it is quicker than checking your feed. So the app is built for the two minutes you actually have: at the bus stop, in line, before the kettle boils.
First question in about two seconds
On a real phone, before the rest of the deck has finished forming. No setup screen, no card to write.
Seven games, one deck
Multiple choice, cloze, flip, match, order, true or false and speed rounds. Facts feel new every time they come around.
Share anything straight in
Highlight, share, done. From any app on your phone, a paragraph becomes a deck in one move.
A nudge only when it matters
The reminder lands the day a fact is about to fade, never because the app wants your attention.
Streaks, for showing up
Two minutes counts. Keep the chain and the day gets its spark; miss one and a freeze can cover for you.
Mastery, when it is truly yours
A deck goes gold once every fact in it has held for months. Zylo brings the confetti.
Gold only ever means earned: a streak, a mastered deck, Zylo's shield.

Real decks, generated by SuperGuide from real text. Every cover is the deck's own colour, so a library never looks like a spreadsheet.
Questions, answered
Frequently asked
How do I remember what 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, and what is FSRS?
Spaced repetition is 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. FSRS is the modern, open algorithm that times those reviews per fact and per person, learning how fast each one fades for you. SuperGuide runs it for every fact in every deck.
Is SuperGuide brain training?
It is memory training on things you actually want to know. Instead of abstract puzzles, you train on your own material: the facts from your notes, your reading, your job, your hobby. The exercise is retrieval, the one that builds memory, and FSRS times it so a two-minute session does the most good.
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. Leave your email at the bottom of this page and you get one message the day it lands. 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.
