Kavke: knowledge that sticks

Kavke turns your study material into a course: short lessons and questions you answer from memory, each one coming back just as you start to forget it. Not a shortcut for the night before.

Lasting knowledge takes effort: searching your head for the answer instead of glancing at the text. That is where it locks in. You bring a few minutes of focus a day; Kavke does the rest.

WHO IT'S FOR
• Medicine, pharmacy, law and biology students — material that must stay for years
• Certification and professional-exam candidates
• Self-taught learners — languages, programming, history
• Big exam months away? Spread it out — spacing beats cramming

HOW IT WORKS
1. Add material: PDF or DOCX (pick pages or chapters), up to 10 photos of notes, your own text, a YouTube video with subtitles, a voice recording, an Anki .apkg deck or just a topic. Or describe your goal in the chat, or turn a conversation from Claude, ChatGPT, Perplexity or Mistral into a course.
2. AI builds the course: lessons split into sections, key concepts for each section, and questions.
3. Read or listen, explain it in your own words, then answer from memory.
4. FSRS-6 spaced repetition brings each question back when it counts. Set a daily reminder if you like.

EXPLAIN IT IN YOUR OWN WORDS
Key sections end with a checkpoint: type or dictate your explanation, and AI shows what you covered and what you missed (the Feynman technique). From the gaps, Kavke can add 3 extra review questions (in your own courses).

AI NARRATOR
Listen to lessons section by section, in 20 languages. The narrator pauses at checkpoints you haven't explained yet, so listening stays part of learning, not a passive podcast.

7 QUESTION TYPES
Multiple choice, true/false, two kinds of fill-in-the-blank, open-ended with AI grading, ordering and matching. AI graded you unfairly? Tap "My answer was correct" and your review schedule is corrected.

PHONE, TABLET, WEB
On a tablet, lessons get a side panel with the narrator, sections and key concepts. Same account and progress on app.kavke.com. App in English, German and Polish. Study groups: share courses with friends, who see only your nickname.

BEFORE YOU DOWNLOAD
• A 400-page textbook won't fit into one course — add it chapter by chapter. Photos count toward OCR pages.
• Anki: we import questions and images, but learning starts fresh and image-occlusion cards are skipped. Import requires an account.
• Questions are text only, even when a lesson shows images.
• YouTube works only with videos that have subtitles.
• Dictation: up to 12,000 words. A lecture recorded from a speaker is transcribed with gaps — speak directly to your phone.
