Lectures into study kits
Free · Designed for iPad. Not verified for macOS.
Most study apps make flashcards. Synapsi makes sure you actually learn them.
Turn any lecture, PDF, or YouTube video into AI-generated flashcards, quizzes, summaries, and mind maps in seconds. Then prove what you know: Synapsi combines real spaced repetition with an AI-powered Feynman teach-back that evaluates whether you can explain concepts in your own words.
Paste a link, upload a file, or drop in your notes. Our AI flashcard maker extracts the key concepts and automatically builds a complete study kit for you.
WHAT SYNAPSI DOES
AI Flashcard Maker
Automatically generate flashcards from any source. Turn PDFs, YouTube videos, lecture slides, and notes into effective study cards in seconds.
Spaced Repetition That Works
A true SM-2 spaced repetition system schedules reviews at the optimal time so information sticks. Perfect for exam prep and long-term retention.
Quiz Generator
Create practice quizzes from your notes and get instant feedback.
AI Summarizer
Turn lengthy PDFs and hour-long lectures into clear, concise summaries.
Mind Map Generator
Visualize how ideas connect with an interactive mind map of your material.
YouTube Transcripts & Notes
Extract transcripts from YouTube videos and instantly convert them into study notes, flashcards, quizzes, and summaries.
Feynman Teach-Back
Explain a concept in your own words. The AI compares your explanation with the source material, identifies gaps in your understanding, and helps you improve. If you can’t explain it, you haven’t truly learned it.
AI Study Chat
Ask questions about your own notes and receive answers grounded in your material, complete with citations.
PERFECT FOR
* Students cramming for exams and finals
* College and university revision
* Medical, law, and language learners
* Anyone who studies from PDFs, lectures, videos, or notes
WHY IT WORKS
Making flashcards can feel like studying, but recognition isn’t the same as recall. Synapsi uses spaced repetition to strengthen memory and the Feynman technique to test whether you can truly explain what you’ve learned.
Stop highlighting. Stop re-reading. Start proving you learned it.
