Learn in your favorite chat.
Deep in a conversation with Claude, ChatGPT, Perplexity or Mistral? Say “save this to Kavke” and what you’ve worked out becomes a course with questions. You do the talking — Kavke makes sure the knowledge stays: spaced reviews plus real understanding checks.

Connect your account
Add the Kavke connector in your chat and sign in — the chat never sees your Kavke password.
- 2
Say “save this to Kavke”
Flashcards from the conversation become questions — the connector picks the right type and can add a short lesson.

Knowledge enters your reviews
The course is waiting in the app, and reviews arrive exactly when you start to forget.
The connector only receives what you consciously send — it can’t read your conversation or history.

Works in Claude, ChatGPT, Perplexity and Mistral (Le Chat)
You do the learning. We remove all the friction.
Your part is a few minutes of focus a day — the active recall that builds lasting memory. The material, the questions and the review schedule take care of themselves.

We check that you understand — not that you recognize an option.
Every app has flashcards and quizzes. The difference is the quality of the signal entering your reviews: you answer in your own words, and AI grades understanding — not a click on a, b or c.
AI grades the meaning of your answer
- Answer in your own words — AI judges the meaning, not a match against a template
- Ambiguous answer? AI asks a follow-up instead of grading right away
- True/false demands a justification — a 50/50 guess isn’t knowledge yet
System 1 vs System 2
System 1: fast, automatic, intuitive. Recognizes faces, reacts to danger. Works effortlessly.
System 2: slow, conscious, analytical. Solves 17 × 24, controls impulses. Requires focus.
Heuristics & traps
Anchoring effect
The first number you hear shifts later estimates — even when it's random. In one study a wheel of fortune was spun before a percentage question — a higher number gave a higher answer.
Availability heuristic
We judge how likely an event is by how easily it comes to mind. After a plane crash in the news, we overestimate the risk of flying.
Confirmation bias
We look for information that confirms what we already believe — and skip the evidence against it.
From course: How We Really Learn
How does System 1 differ from System 2 in thinking?
Your answer:
System 1 is fast and automatic, System 2 slow and analytical.
Give an example of a decision driven by System 1.
When I hit the brakes reflexively before thinking.
“Explain it” — the Feynman method
You explain the topic in your own words, as if teaching someone else. AI scores how complete the explanation is against a rubric — kindly, without nitpicking style.
Gaps in your explanation come back as flashcards in your reviews.
Questions about what matters
Questions are built from each lesson’s key concepts — never padded to a count
Confidence calibration
Mark how sure you are before answering — and see where confidence drifts from results
No made-up facts
Topic courses are grounded in sources, and the AI is barred from inventing facts and dates

The FSRS algorithm reminds you to review exactly when you’re starting to forget — the moment the memory trace strengthens most. You study less and remember longer.
FSRS algorithm
A newer standard than Anki’s SM-2 — more retention, fewer hours
Smart scheduling
Reviews come back on their own at the key moment, not daily
Mixed reviews

Three mechanisms behind all real learning.
Retrieval practice
You learn when you pull knowledge out of memory — not when you read it one more time.
Desirable difficulties
What’s harder during study builds stronger long-term knowledge. Easier ≠ better.
Spacing effect (FSRS)
A question returns as you start to forget it — when the memory trace strengthens most.

How memory works — and how reviews make it last
Learn something once and you forget it within days. Kavke schedules short reviews exactly when you start to forget — and each one locks it in for longer. Try the sliders.

This chart runs the same FSRS model that powers Kavke (power-law curve). Active recall and spaced reviews are among the most robustly documented learning techniques (meta-analyses: Rowland 2014; Adesope et al. 2017; Latimier et al. 2021).
An app that teaches you how to learn
Your first course after sign-up — “How we really learn” (7 lessons) — teaches exactly these mechanisms. You start by understanding how your memory works.

13 question types
Multiple choice, true-false with justification, open questions, fill-in-the-blanks, matching pairs, ordering, calculations, scenario-based application… AI fits the question type to the content and grades open answers semantically — asking a follow-up when an answer is incomplete.
Questions that aim at your weak spots.
Adaptive tests find your gaps — you don’t waste time on what you already know. Turn weaknesses into strengths.
AI narrator & voice answers
Read every lesson or listen to it (AI narrator), and answer open questions by voice — learning works on a walk or in the car too.
