EchoPal turns your notes into a hands-free study session. Upload a PDF, PowerPoint, or paste any text, and EchoPal instantly builds flashcard-style questions from your material. Then it reads each question aloud, listens to your spoken answer, and gives you real feedback! No typing required! Study while you cook, drive, clean, or work out. EchoPal keeps track of what you get wrong and brings those questions back automatically so nothing slips through the cracks. KEY FEATURES • Hands-free voice sessions: questions read aloud via text-to-speech, answers captured by microphone. No screen interaction needed. • AI-powered question generation: upload a PDF, PPTX, or paste text and EchoPal builds targeted questions from your content. • Instant explanations: get a question wrong and EchoPal explains why, then lets you ask follow-up questions until you actually understand. • Automatic weak-spot targeting: missed questions cycle back into the session so you keep practicing what matters most. • Session summary: see your score, accuracy, and time spent after every session. • Multiple voice options: choose from a range of TTS voices to match your preference. • Try before you sign up: tap "Try a Demo" on the landing screen to experience a full voice session with no account required. BACKED BY SCIENCE Active recall has been shown to outperform passive review by a wide margin. Students who test themselves on material remember significantly more after a week than those who simply re-read notes. EchoPal is built around this principle.

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 study app built around that idea. Paste any YouTube video, PDF, or your own notes — Rekal generates a personalized quiz in seconds, lets you answer out loud, and AI grades how well you actually understood it. If you can explain it, you know it. If you can't, now you know exactly what to review. HOW IT WORKS 1. Paste anything — a YouTube URL, PDF, or typed notes. Rekal extracts the key concepts and generates a quiz tailored to your content. 2. Speak your answer — explain it out loud, the way you'd explain it to a tutor. Or type it. Or pick multiple choice. Your call. 3. Get real feedback — semantic AI grading tells you what you understood, what you missed, and why. Not just right or wrong — actual explanations that fill the gaps. WHY VOICE GRADING IS DIFFERENT Active recall — retrieving information from memory — is 2-3x more effective than passive review. Speaking forces deeper retrieval than tapping a flashcard. And 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. Explanations that show you why an answer is correct. The result: you don't just memorize — you actually learn. FEATURES - Voice answers, AI graded — speak naturally, get evaluated on what you mean - Quiz from any source — YouTube videos, PDFs, typed notes, articles - Multiple modes — voice, type, or multiple choice; switch any time - Practice mode — hide scores, study without pressure - Quick Review — 2-minute micro-sessions for between classes - No streaks, no guilt notifications, no shame — open the app when you're ready WORKS FOR ANYTHING YOU'RE LEARNING - College finals — paste lectures or PDFs, get instant quizzes - AP exams — Bio, Chem, Calc, US History, any AP subject from your materials - Professional certs — nursing, CPA, PMP, AWS, pharmacy, real estate - Self-directed learning — YouTube videos, podcasts, articles, books - Standardized tests — includes a built-in 5,000-question SAT and ACT bank SAT, ACT & AP Rekal includes a curated bank of 5,000 SAT and ACT practice questions (2,000 SAT + 3,000 ACT). Choose your test, pick a section, set your difficulty — quiz yourself with timed or untimed sessions. For AP and other tests, paste your own study materials and Rekal makes a quiz from them. PRICING Free — 5 quizzes per month, up to 10 questions each, voice and text answers included. No credit card. No trial. Free means free.
