About this app

Kavke turns any source — a YouTube video, PDF, photo of handwritten notes, or voice recording — into a ready-to-study course with questions you answer from memory. This is not a shortcut for the night before.

Lasting knowledge takes effort from you — moments of focus, attempts to actively recall, the moment you search your head for an answer instead of glancing at the text. That moment is where knowledge locks in — not a bug to remove, but the reason it works. Passive reading gives you the illusion that you "know it"; only pulling it from memory tests whether you really do. Our job: break the material into small units, schedule each review for the moment you'd start to forget (FSRS), and automate everything you needn't hold in your head. Yours: a few minutes of real focus a day. If you're after something that learns for you — this isn't it. If you want to remember for years, not for tomorrow — finally, yes.

WHO IT'S FOR
• Med, law, biology and pharmacy students — hundreds of definitions and mechanisms that must stay for years, not just for the exam
• People preparing for certifications and professional exams — who want to pass and STILL remember it, because they use it at work
• Self-taught language, programming and technical learners — studying for themselves, long-term, not just to "feel like they know it"
• Anyone whose appetite for learning has come back and who finally has the time — to master, at a calm pace, a subject they always wanted: history, philosophy, a language. No exam, just for its own sake
• Got a big exam months away and don't want to cram the night before? Spread it out — spacing beats cramming (no miracle by tomorrow)

Kavke teaches with text, questions and an audio narrator — no diagrams or graphics inside lessons. It works best on material you can put into words: facts, definitions, concepts, languages. If your subject lives in pictures (anatomy atlases, geometry, charts) — this isn't the tool for you.

WHAT MAKES US DIFFERENT
Cognitive-science mechanisms documented for decades:
• Retrieval practice (active recall) — you learn when you PULL knowledge from memory, not when you re-read it
• Desirable difficulties — what feels harder during study (open-ended questions, mixed reviews, longer gaps) builds stronger long-term knowledge. Easier ≠ better — and that's no accident
• Spacing effect (FSRS) — a question returns right when you're starting to forget it; that's how what you learn stays for months and years, not just until the exam

HOW IT WORKS
1. Pick a source: YouTube, text, PDF, photo, voice, or a topic
2. AI prepares the structure, lessons and questions — the material to study, not ready-made knowledge
3. The rest is on you: read or listen, then answer the questions from memory
4. Reviews come back at the right moment (the FSRS algorithm)

6 SOURCES: YouTube, any topic, text/notes, PDF/DOCX, photo of a page (OCR reads handwriting), voice recording.

SMART REVIEWS
FSRS — the latest spaced repetition standard (better than SM-2 used in Anki). Smarter reviews, not cramming: you return less often, but when it counts.

13 QUESTION TYPES: single/multiple choice, true/false, open-ended (AI-validated), ordering, matching and more — AI picks the type.

AI NARRATOR
Listen to lessons on the go — then answer from memory. The narrator (PL & EN) is part of the recall loop, not a passive podcast — it reads the lesson text, it's not a conversation course.
