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. Full study kits and the AI study tools below require a Synapsi Pro subscription or one-time lecture credits. WHAT SYNAPSI DOES (requires Pro or lecture credits) AI flashcard maker: auto-generate flashcards from any source. PDF to flashcards, YouTube to flashcards, lecture notes to flashcards. 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. It isn't. Real learning is recall and explanation. Synapsi uses spaced repetition to make you recall and the Feynman technique to make you explain. Stop highlighting. Stop re-reading. Start proving you learned it. SUBSCRIPTION & CREDITS Synapsi is free to download. Your first study kit is a free preview.

Housekeeping under the hood. Nothing changes in how you study. ### 1.9.0 — 2026-08-28 Smarter reminders. One nudge a day, built from what's actually due: cards about to slip, a streak at risk, an exam getting close. Quiet when nothing needs you. Exam dates. Set a deadline on any note and Synapsi plans reminders back from it: a week out, 3 days, the day before, and a pep talk that morning. Tapping a notification now jumps straight to the right place. Fixes throughout, including a Mac crash at sign-in. ### 1.8.0 — 2026-08-25 Lecture credits now unlock the whole lecture. One credit buys the full study kit: every flashcard, every quiz question, the complete mind map and summary, plus the Feynman test. Credits never expire. Polish and fixes throughout. ### 1.7.0 — 2026-08-24 Turn anything into a study kit. Paste an article link, or a TikTok, Instagram, Facebook or X video, right alongside YouTube, PDFs, audio, and your own text.

Your library got a face. Notes now show real video posters and creator names. Videos with captions turned off can now be transcribed automatically on Pro. Faster, smoother, and more polished throughout. ### 1.6.4 — 2026-08-11 Fixes subscription plans failing to load on the upgrade screen, and shows a clearer message when the App Store cannot return them. ## More apps by Khoa Tran - [Rescue The Pet](https://appshunter.io/ios/app/rescue-the-pet/id1661397255) - [MiloLingo - English Mastery](https://appshunter.io/ios/app/milolingo-english-mastery/id6451000168) - [Heo - Expense Tracker](https://appshunter.io/ios/app/heo-expense-tracker/id6782393356) All apps by Khoa Tran: https://appshunter.io/developer/1523512472 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
