Most study apps make the flashcards. Synapsi checks you actually learned them. Turn any lecture, PDF, or YouTube video into AI flashcards, a quiz, a summary, and a mind map in seconds. Then prove you know it: Synapsi runs real spaced repetition and an AI-judged Feynman teach-back that grades whether you can explain the idea in your own words. MORE SOURCES, SAME STUDY KIT Synapsi also reads web articles and short video links from TikTok, Instagram, X, and Facebook. Paste the link, get the transcript and the full study kit. Free tools (transcript, summarizer, flashcard maker) live at synapsi.guru/tools and need no account. Synapsi is free to download and includes a free preview: your first study kit, with a sample of its flashcards, quiz, and summary.

Spaced repetition that works: a real SM-2 system schedules reviews at the right time so facts stick. Built for exam prep and revision. Quiz generator: turn your notes into a practice quiz with instant feedback. AI summarizer: get a clean summary of a long PDF or hour-long lecture in seconds. Mind map generator: see how ideas connect with a visual mind map of your material. YouTube transcript and notes: pull the transcript from any video and turn it into study notes, flashcards, and a quiz. Feynman teach-back: explain a concept, and the AI judges your answer against the source and shows your gaps. If you can't explain it, you haven't learned it yet. AI study chat: ask questions about your own notes and get answers with citations. Smart reminders: one nudge a day, built from what is actually due. Set an exam date and Synapsi counts down to it. PERFECT FOR - Students cramming for exams and finals - College and university revision - Med, law, and language learners - Anyone who reads PDFs or watches lectures and wants to remember them WHY IT WORKS Making flashcards feels like studying.
