About this app

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.

★ FEATURES

▸ Voice-First Study App
Speak your answer instead of tapping. On-device speech processing means your audio stays on your phone. Your AI study buddy listens, understands, and grades.

▸ AI Quiz Generation from Any Content
Turn a YouTube video into a quiz. Convert a PDF to quiz questions. Paste your notes and get a personalized quiz in seconds. No manual flashcard creation.

▸ Semantic AI Grading
AI grading that understands what you mean, not just what you type. Every grade includes a confidence score so you know how sure the AI is.

▸ Explanations That Stick
Every question includes feedback — what you understood, what you missed, and why. Real explanations that help you remember what you learn.

▸ Multiple Answer Modes
Voice, typed text, or multiple choice — switch any time.

▸ Practice Mode
Hide scores entirely. Study without pressure. No judgment, just feedback.

▸ Quick Review
One-tap micro-sessions. Review a single question in 30 seconds. Stop forgetting what you studied yesterday.

★ NO SHAME. NO GUILT. NO BACKLOGS.

No streaks, no "you missed 5 days" notifications, no backlog pile-ups. Open the app when you're ready. It's ready too. A study app without anxiety — built for how students actually study.
