Turn your NotebookLM notes into flashcards with AI
Upload PDFs, slides, notes or photos of pages, and DeckOwl builds flashcards with spaced repetition so the material sticks.
Studying NotebookLM material with flashcards
Once your research lives in NotebookLM, you still need a way to memorize it, and a flashcard app for NotebookLM material turns those sources into cards you can review on a schedule.
- Generate cards from PDFs, DOCX, PPTX, plain text or photographed pages
- Review with spaced repetition so weak cards come back sooner
- Check each card against the original source before you rely on it
- Export to Anki, PDF, DOCX or CSV on the Plus plan
Starts from your own sources
Upload the PDFs, slides, notes or images you study from, including photos of printed pages read with text recognition.
Spaced repetition built in
Cards come back at growing intervals, timed to just before you would forget them, so review time goes to what you are losing.
Quizzes and mind maps too
Turn the same material into multiple choice, true/false and short answer questions with explanations, or a mind map of the main ideas.
How it works
Add your material
Upload a PDF, DOCX, PPTX, plain text file or photo of your notes. Use the same sources you research with in NotebookLM.
Generate flashcards
DeckOwl reads the text and proposes cards with a question or term on the front and the answer on the back.
Review on a schedule
Study in your browser each day. Cards you miss return sooner, and cards you know drop back in the rotation.
Summaries and chat answers are easy to reread and easy to forget. Flashcards force recall: you see the question, answer from memory, then check the card against the original source. That check also catches any detail an AI summary got wrong.
DeckOwl takes the files you already have, such as PDFs, slides and notes, and produces cards you can edit before you study. The free plan covers three generations a month, and paid plans add unlimited generations and exports.

Frequently asked questions
How many flashcards should I make from one NotebookLM source?
Make one card for each distinct fact, definition or cause in the source. Drop any card you would not actually need to recall on an exam.
Does spaced repetition work better than rereading summaries?
Spaced repetition usually works better because it makes you retrieve the answer at growing intervals. Try to answer from memory before you check the back of the card.
Can I export my flashcards to Anki?
Yes, Anki export is included in the Plus plan, which costs $99.90/year or $9.99/month. Students get 40% off with a school email.
Is there a free plan?
Yes, the free plan includes 3 generations per month and studying in the browser, and no credit card is needed to start. Exports require a paid plan.
