The TikTok for studying

Yes. DoomStudy is a free study app that works like TikTok, but every card in the feed comes from your own course material. You upload your PDFs, PowerPoints or Word documents, and AI turns them into short facts, key concepts, Q&A cards, true/false questions and multiple-choice quizzes. You then swipe through them in an endless vertical feed, with optional looping video backgrounds, exactly like you would scroll social media. It is available for free on iPhone, iPad and Android.

The quickest way is to upload your notes to an AI study app like DoomStudy. Create a course, add your PDF, PPTX or DOCX files, and the app extracts the text and generates bite-sized study cards for you: facts, key concepts, Q&A, true/false and multiple-choice questions. You choose which card types you want and how many cards each document produces. There is no typing cards by hand, and the result is a scrollable feed you can review anywhere. DoomStudy is free on iPhone and Android.

Yes. AI can read a PDF and write quiz questions from it, and DoomStudy does this automatically. Add a PDF (or a PowerPoint or Word file) to a course and the app generates multiple-choice questions, true/false questions and Q&A cards based only on that material. Quizzes appear in your feed between facts and concepts, so you practise active recall while you scroll. You can pick which files are used for generation and which question types you want. DoomStudy is free to download on iOS and Android.

Keep the scrolling habit and change what you scroll. Willpower alone rarely beats an app designed to be addictive, so a practical trick is to replace the feed rather than fight it. DoomStudy gives you the same swipe-for-the-next-card experience as TikTok or Reels, but every card is a fact, concept or quiz question from your own classes. When you reach for your phone out of habit, open DoomStudy instead and you are reviewing for your exam within a second. The app is free on iPhone and Android.

Yes, DoomStudy is free to download and use on iPhone, iPad and Android. There is no subscription and no paywall on generating study cards. The project is also open source under the MIT license, so anyone can read the code on GitHub. You can generate cards with Google Gemini in the cloud, or download an offline AI model to your phone and generate cards on-device. On supported iPhones running iOS 26 or later you can also use Apple Intelligence.

Yes. DoomStudy can generate and show study cards with no internet connection. You can download an on-device AI model (such as Llama 3.2, Phi 3.5 or Qwen 2.5) once, and from then on your notes are turned into cards locally on your phone, on both iPhone and Android. On compatible iPhones with iOS 26 or later, Apple Intelligence is another on-device option. Your courses, cards and progress are stored on your device, so you can study on a plane, on the subway or anywhere without signal.

Your study materials and progress are stored locally on your device, and DoomStudy has no user accounts. If you use an offline model or Apple Intelligence, your documents never leave your phone. If you choose Google Gemini, the text of your documents is sent to the Gemini API to generate cards, and only when you pick that option. You can delete any course, document or all of your data from inside the app at any time, and uninstalling the app removes everything.

DoomStudy supports PDF, PowerPoint (PPTX) and Word (DOCX) files. When you add a file to a course, the app extracts its text automatically and uses it to generate study cards. That covers most lecture slides, course readers, handouts and typed notes. You can add several files to the same course, organize courses with custom tags, and toggle which files are used when new cards are generated. It is free on iOS and Android.

Yes. DoomStudy is available for free on Android through Google Play, as well as on iPhone and iPad through the App Store. The Android version supports the same core features: uploading PDF, PPTX and DOCX files, AI-generated facts, concepts, Q&A, true/false and multiple-choice cards, video backgrounds, and offline on-device AI models. Apple Intelligence is the only option that is iPhone-only, because it is built into iOS.

Active recall is a study technique where you try to retrieve an answer from memory instead of rereading it. Research on the "testing effect" shows that practising retrieval produces stronger long-term memory than highlighting or rereading notes, because each attempt strengthens the memory you are trying to recall. DoomStudy builds active recall into your feed with Q&A cards, true/false questions and multiple-choice quizzes generated from your own notes, so you test yourself every few swipes. It is free on iPhone and Android.
