An app for remembering and reviewingNew: works with Claude, ChatGPT & more

Short sessions,
results for years.

Kavke isn’t another generator of text you read once. It turns an AI conversation, a document or a recording into questions, then brings them back exactly when you start to forget. You put in a few minutes a day.

How Kavke works

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.

  1. 01

    Add

    An AI chat, a YouTube video, a PDF, a photo of a page, a recording or just a topic — Kavke turns it into review questions, with a short lesson underneath.

  2. 02

    Answer

    In your own words, by text or voice — in the quiz and at Feynman checkpoints inside the lesson. AI grades the meaning of your answer, not a click on a, b or c.

  3. 03

    Retain

    The FSRS algorithm reminds you to review exactly when you start to forget.

Read it once

  • AI writes the text, you read it
  • A week later a few percent remain
  • You start over from scratch

Remember for years

  • You answer from memory, in your own words
  • The review returns before you forget
  • Every session stretches the gap to the next

Start with anything. We’ll handle the rest.

A YouTube video, notes, a PDF, a photo of a page, a lecture recording, just a topic — or a plain chat conversation. Kavke turns it into a ready course with questions. The course isn’t the goal. It’s fuel for questions and reviews.

AnswerCore

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

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.

You’ve got the core: fast–automatic vs slow–analytical

Missing: a real-life example

Follow-up Question

Give an example of a decision driven by System 1.

When I hit the brakes reflexively before thinking.

The gap comes back as a flashcard in reviews

“Explain it” — the Feynman method in every lesson

After each section of a lesson, a short checkpoint: explain what you just read in your own words — by voice or text, as if teaching someone hearing it for the first time. At the end, you retell the whole lesson.

AI scores how complete the explanation is against a rubric — kindly, without nitpicking style.

Why it matters: reading gives you the illusion of understanding. Only saying it out loud, in the simplest words you can, shows what’s really missing — and that effort is exactly what writes knowledge into memory.

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, the AI is barred from inventing facts and dates, and each question shows its source quote

Remember for good, no cramming.

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

You know when they return

After a quiz you see when each question comes back — nothing gets lost

Mixed reviews

Questions from different courses, interleaved — a true memory test

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.

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.

Expiry date, sign-in required

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. Don’t know? Tap “show the answer” or jump back to the lesson — no pretending.

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. The AI narrator reads section by section and highlights the one you’re hearing; you control it from the lock screen. Answer open questions and Feynman checkpoints by voice — learning works on a walk or in the car too.

Learning a language?

Tell Kavke which language you’re learning and the questions will practise the target language instead of translating it. Six languages to choose from.
