Rekal: AI Study Buddy & Quiz

Paste a YouTube lecture. Speak your answer. Find out what you actually know.

People forget up to 70% of new information within 24 hours. Re-reading doesn't fix it. Highlighting doesn't fix it. The only thing that does: explaining what you learned, in your own words, out loud.

Rekal is the voice-first AI study app built around that idea. Paste any YouTube video, PDF, or your own notes — Rekal generates a personalized quiz, lets you speak your answer out loud, and AI grades how well you actually understood it. If you can explain it, you know it.

Tired of flashcard burnout? Done with passive re-reading? Rekal is the study app built for how learning actually works.

★ HOW IT WORKS

1. Paste anything — YouTube URL, PDF, typed notes. Rekal extracts the key concepts in seconds.
2. Speak your answer — explain it out loud the way you'd explain it to a tutor. Or type it. Or choose multiple choice.
3. Get real feedback — semantic AI grading tells you what you understood, what you missed, and why.

★ WHY VOICE GRADING IS DIFFERENT

Active recall is 2-3x more effective than passive review. Speaking forces deeper retrieval than tapping a flashcard. Explaining out loud is the Feynman technique: if you can teach it, you understand it.

Rekal grades meaning — not word-for-word matching. Partial credit for partial understanding. You don't just memorize. You actually learn.
