Turn your PDFs and notes into free AI flashcards online
Upload a PDF, slide deck, set of notes or a photo of a page. DeckOwl reads the text and builds flashcards you can study right away in your browser.
How free online AI flashcards help you study
Studying from a 60-slide lecture deck or a long chapter is hard to do card by card, which is why many students look for free online AI flashcards they can build from their own material. DeckOwl reads the file and turns key terms and ideas into question and answer cards you can start reviewing in minutes.
- Make cards from PDFs, slides, DOCX files, notes and photos of pages
- Review on a spaced repetition schedule that adjusts to your mistakes
- Study in the browser on the free plan with 3 generations a month
- Export to PDF, DOCX, Anki or CSV on Plus, with 40% off for students using a school email
Works with your own material
Upload PDF, DOCX, PPTX, plain text or images. Photos of pages are read with text recognition.
Spaced repetition built in
Cards come back at the right time, so you review what you are about to forget instead of what you already know.
Start free, no card needed
The free plan includes 3 generations a month and studying in the browser. Exports and unlimited generations are on paid plans.
How it works
Add your material
Upload a file, paste your notes or take a photo of a textbook page.
Generate your cards
DeckOwl pulls out terms and definitions and writes question and answer cards from them.
Study on a schedule
Review each day in short sessions and let spaced repetition decide when each card returns.
The cards are only useful if you come back to them, so DeckOwl schedules reviews with spaced repetition. Cards you miss show up again sooner, and cards you know drop out of the rotation. You can start on the free plan without a credit card and study everything in the browser.
If you later need to move cards into another app, the Plus plan adds PDF, DOCX, Anki and CSV export along with unlimited generations.

Frequently asked questions
Is DeckOwl really free to use?
The free plan includes 3 generations per month and studying in the browser, and you do not need a credit card to start. Exporting files and unlimited generations require the Plus or Pro plan.
How many flashcards should I make for one topic?
Make cards for the ideas you need to recall, not for every sentence in the source. Focus on terms, definitions, and cause-and-effect relationships, and split a long chapter into smaller sections.
How should I study flashcards to remember vocabulary?
Review a small set every day rather than cramming a large set once a week. Say the answer out loud before you flip the card, and mark cards you missed so they come back sooner.
Can I export my cards to Anki?
Yes, export to Anki is available on the Plus plan along with PDF, DOCX and CSV export. The free plan lets you study cards in the browser without exporting.
