DoomStudy · AI flashcard maker
Turn your PDFs and slides into flashcards with AI
Writing flashcards by hand takes longer than studying them. DoomStudy reads your PDF, PowerPoint (PPTX) or Word (DOCX) files and generates flashcards for you: Q&A cards, key concepts, facts and true/false questions.
The cards land in a swipeable feed on your phone, so you can review a full lecture in a few minutes without typing a single card.
Free on iPhone, iPad and Android
How it works
Upload a file
Add a PDF, PPTX or DOCX to a course. Text is extracted automatically.
Pick card types
Choose facts, concepts, Q&A, true/false, multiple choice or your own custom card types.
Review in a feed
Swipe through the generated cards and test yourself anywhere, online or offline.
Which files can you turn into flashcards?
DoomStudy supports PDF, PowerPoint (PPTX) and Word (DOCX) files, which covers most lecture slides, course readers, handouts and typed notes. Add as many files as you want to a course.
You can toggle individual files on or off, so new cards only come from the chapters you are studying right now.
Flashcards that test you, not just remind you
Besides classic question-and-answer cards, DoomStudy generates true/false and multiple-choice questions from your material. Answering them is active recall, which strengthens memory far more than rereading a summary.
You decide how many cards each document produces and which types are mixed into your feed, and you can define custom card types for your subject.
Online or fully on your phone
Generate flashcards with Google Gemini in the cloud, or download an offline model such as Llama 3.2, Phi 3.5 or Qwen 2.5 and generate them on your device on both iPhone and Android. On iOS 26 and later, Apple Intelligence is also supported.
With an on-device model, your documents never leave your phone.
