Facit Facit remembers what you're about to forget.
Flashcards that schedule themselves. Build a deck from your notes — or a table from ChatGPT — and beam it to your phone with a single animated QR code.
Fill the deck fast: copy a table — a question in the first column, its answer in the second — from ChatGPT, a spreadsheet or a web page, then hit AI paste. Add more columns of wrong answers and a row becomes a multiple-choice card. The QR updates as you edit.
🤖 Prompt for flashcardsQuestion on the front, answer on the back
Make flashcards from the material I've attached or pasted below. If there's no material, ask me what topic I want first. - If the material is a list (like a word list), make exactly one card per item — don't add or skip any. - Otherwise, make one card per key fact or idea — at most 15, fewer if the material is short. If I ask for a different number, use that. - Never add cards just to reach a number. - Match the level of the material. - Write in the same language as the material (or as my message, if there's no material). Reply with only a Markdown table with two columns: Question | Answer. - One card per row. - Keep each question to one clear fact or idea. - Keep each answer short — a word, a phrase or one sentence. - Use $…$ for any math (LaTeX). - Never use the | character inside a cell, not even in math (write \lvert x \rvert instead).
Paste it into ChatGPT, Claude or Gemini, then attach your notes, a photo or a file — or just name a topic.

What a flashcard actually does
A flashcard is a prompt and a response: Capital of Sweden on the front, Stockholm on the back. You try to produce the answer from memory before you flip. That small struggle — active recall — is the whole point.
Re-reading a page feels productive and mostly isn't. Pulling the fact back out of your head is what builds a memory that lasts. Facit keeps every card to one clean question so the recall stays honest, and one clean answer so grading yourself is unambiguous.
Spaced repetition, drawn
A new fact decays on a predictable curve — strong today, shaky in two days, mostly gone in a week. Review it just before it slips, and the curve resets, flatter each time. The next safe gap grows: days, then weeks, then months.
Facit tracks every card's strength and picks that moment for you. Cards you find hard come back tomorrow; cards you know cold get out of your way. You only ever study the handful you're about to lose.

From a chat table to a deck, in a minute
You don't have to type a hundred cards. Any assistant that can make a table can make a Facit deck.
-
Ask for a table
Prompt ChatGPT, Claude or Gemini for a two-column table: term and translation, concept and definition, question and answer. Want multiple choice? Ask for extra columns of wrong answers — or copy a ready-made prompt from the deck builder.
-
Press AI paste
Copy the table, open the builder, hit AI paste. Facit reads Markdown tables, spreadsheet rows and HTML tables from your clipboard and fills every card.
-
Scan the signal
The deck is compressed, split and looped into an animated QR code. Point the app at your screen — no file, no login, no typing on glass.
What's in the app
Move decks between devices
Share a deck from one Facit app to another, or build it in a browser and send it straight to the app.
AI paste
Markdown, TSV/CSV and HTML tables from ChatGPT, Sheets or Notion become cards in one click — then fix any question or answer in the builder before you scan.
Multiple choiceNew
Give a card wrong answers — or paste a table with extra columns — and it becomes a quiz: pick the right one from shuffled options. Right counts as known; wrong comes back to repeat.
Self-scheduling reviews
Every card carries a strength and a next-due date. Facit computes the interval; you just show up.
Due date
Set the day you need the deck learned by and Facit paces your reviews to get you there.
Offline by default
Decks live on the device. Study on a train, a plane, or a basement lecture hall.
Before you download
Is Facit free?
Downloading Facit and importing decks from a QR code is free.
Do I need an account?
No. The animated QR code carries the entire deck, so there's nothing to sign up for and nothing to sync.
Which AI tools work with AI paste?
Any that can output a table — ChatGPT, Claude, Gemini — or a plain spreadsheet. Two columns make flashcards; further columns are wrong answers for multiple-choice cards. Facit parses the table, not the tool.
Can I make multiple-choice cards?
Yes. Add wrong answers to a card and Facit shows the correct answer and the wrong ones as buttons in random order — pick right and the card counts as known, pick wrong and it comes back to repeat. From an AI, ask for a table like: Question | Correct answer | Wrong answer 1 | Wrong answer 2 | Wrong answer 3. Column 2 is always the correct answer. Flashcards and multiple-choice cards can share a deck. Older versions of the app import multiple-choice cards as ordinary flashcards.
How large can a deck be?
There's no fixed limit. Bigger decks simply add QR frames and take a few seconds longer to scan.
Can cards use Markdown or math?
Yes. Card text takes Markdown for emphasis, lists and code, and LaTeX for formulas — write $E=mc^2$ inline or $$…$$ for a centred block. The builder shows every card rendered; click a question or answer to edit it.
Where does my data go?
The builder runs in your browser. Nothing is uploaded; the QR code is generated locally on this page.
