Turn the videos you already watch into flashcards, a quiz and notes β€” then actually remember them. Paste a link and Stubey builds the study pack for you, in seconds, on your iPhone. FROM A LINK TO A STUDY PACK β€’ Paste a video link and Stubey fetches the captions on its own. No copying, no browser. β€’ No captions? Pick the audio or video file instead and it is transcribed on this device. β€’ Or paste a transcript you already have. β€’ Out comes a brief, the key takeaways, a deck of flashcards and a multiple-choice quiz, all built from what was actually said. PRACTICE THAT STICKS β€’ Tap to flip, swipe to answer. The cards you keep missing come back first. β€’ Quizzes are generated from the same transcript, so you are tested on the real material. β€’ Quick Practice pulls a session out of any collection when you have ten minutes. β€’ Every card and question is editable, and you can write your own from scratch. A ROUTINE, NOT A CRAM SESSION β€’ Set a daily target in cards or in minutes. β€’ Choose the weekdays you study, and a date you want to be ready by. β€’ Get a reminder at the time you pick. β€’ A streak, a month grid and a year heatmap show every day you showed up. ORGANIZED BY SUBJECT β€’ Group lessons into collections with their own icon and color. β€’ Point a study plan, or a single practice run, at one collection or at everything. β€’ Favorites, archive, search and sort across the whole library. REAL NOTES BESIDE EVERY LESSON β€’ A proper editor: headings, bold, highlights, colors, checklists, numbered and bulleted lists. β€’ Your notes sit next to the transcript, the cards and the quiz for that lesson. TWO WAYS TO GENERATE β€’ On device: built by Apple Intelligence on your iPhone. Free, unlimited, offline, and nothing leaves the device. β€’ In the cloud: sharper flashcards, quizzes and summaries, on any supported iPhone, with or without Apple Intelligence. Transcripts are sent to Stubey to be processed. β€’ Switch between the two in Settings whenever you like. YOURS, AND ONLY YOURS β€’ Lessons, transcripts, notes, quizzes and flashcards are stored locally on your device. β€’ Imported files are never copied out of where you keep them. β€’ No account. No sign-up. Nothing to log in to. MADE FOR Lecture recordings and seminars. Conference talks and tutorials. Podcasts and interviews. Language listening practice. Certification and exam revision. Anything you would otherwise watch once and forget. FREE, AND PRO The whole loop is free: import, generate, practice, plan and track.
