Flashcards that ask a new question at every review.
Bring your Anki decks with their schedule. LearnForge rewrites each card's question when it is due and asks one level higher once you keep getting it right.
No credit card. €4.99 a month afterwards. The rewritten questions run on your Claude account or on your own API key.
One card, asked three ways
Tap an answer. It is the same card each time, with a different question.
What causes the seasons on Earth?
Example card. In LearnForge, Claude writes such questions from your own cards, in Claude chat or in the app with an API key.
What happens when a card is due
See the same card often enough and you start to recognise the card instead of recalling the idea. LearnForge changes the question, so that shortcut stops working.
The question is rewritten
By default each review rewords the question and moves it to a slightly different setting. You set how far that goes per card or per topic.
- Exact
- Asked word for word
- Reworded
- Same question, different wording
- New context
- Same idea in a new situation
- Free
- Anything that tests the idea
Every card has a level
There are six levels, from recalling a fact to building something with it. Keep answering well and the card moves up a level. Miss it and it steps back. Cards set to Exact stay on their level.
- 1 Remember
- 2 Understand
- 3 Apply
- 4 Analyze
- 5 Evaluate
- 6 Create
Tap, type or dictate
Pick a session difficulty and how you want to answer. Open answers are graded, and you can ask follow-up questions afterwards. All of this needs the tutor: Claude chat, or the app with your own API key.

FSRS decides when
The FSRS algorithm schedules every card from how you rated it. After harder sessions and more varied questions, the next interval is longer.
Get your cards in
Import from Anki
Upload an .apkg or .colpkg file from a current or older Anki version. Decks and media come along, and you choose whether to keep your schedule. Image occlusion cards come along too, ready to study.
Create them in Claude chat
Connect LearnForge to Claude and say what you are learning. Claude drafts cards with formulas, diagrams and cloze gaps, and saves them once you approve.
Write them yourself
Write and edit cards in the web app. No AI involved.
Get a topic by link
A link from someone else copies a whole topic with its cards into your account. Your progress starts at zero.
Two places to study, and what each costs
The LearnForge subscription pays for hosting. AI usage is separate, and you choose how to cover it.
In Claude chat
- Claude asks the questions and grades your answers
- No API key needed, it runs on your Claude account
- Set up once: paste the LearnForge address into Claude's settings (Claude calls this a connector)
In the LearnForge app
- A web app you can add to your phone's home screen
- The built-in tutor needs an API key: a code from your own Anthropic developer account, billed by usage
- Without a key you study the plain cards and rate yourself. FSRS still schedules every card.

Questions
What is LearnForge?
LearnForge is an open-source flashcard app with spaced repetition. When a card is due, an AI tutor rewrites its question, the app tracks one of six levels of understanding per card, and the FSRS algorithm plans the next review.
Do I need a Claude subscription or an API key?
For studying in Claude chat you need a Claude account with LearnForge added as a connector, and no API key. For the tutor inside the LearnForge app you need your own Anthropic API key, which Anthropic bills by usage. With neither you can still study your cards in the app and rate yourself.
Can I bring my Anki decks?
Yes. LearnForge imports .apkg and .colpkg files from current and older Anki versions. Decks and media come along, and you choose whether to keep the schedule of every card. Image occlusion cards come along too, ready to study.
Does the question really change every time?
By default, yes: each review rewords the question and moves it to a slightly different setting. You can set a card or a topic to Exact, and then it is asked word for word. In the app, cards that depend on a picture or a formula are shown as they are, and without an API key you see every card as it is.
What does LearnForge cost?
The first 30 days are free and need no credit card. After that the hosted version costs €4.99 a month, or €48 a year. Self-hosting is free under the AGPL-3.0 licence. AI usage is billed separately by Anthropic.
What are the six levels?
They follow Bloom's Taxonomy: Remember, Understand, Apply, Analyze, Evaluate and Create. Each card has its own level. It goes up when you keep answering well and steps back when you miss.
