What open source means for your Anki deck

Anki itself is free and open source, which is why many students want open source Anki flashcards they can keep and move between tools. DeckOwl is not open source, so it does not give you the source code. What it does do is turn your own lecture slides, PDFs and notes into flashcards you can study with spaced repetition and export to Anki.

Anki's source code is public, so you can read how its scheduling works.
Look for a license such as MIT or GPL before reusing any open source study tool.
Export to Anki is a Plus feature; the free plan studies in the browser only.
Keep a backup copy of exported decks so you can restore them on another device.

Export to Anki

On Plus, export your deck to Anki and keep studying there.

A practical way to use Anki well is to keep each card to one fact, write the question in your own words, and review a little every day instead of cramming. Open source tools reward that habit because your deck stays in files you can back up and control.

If you need open source software itself, check the project's license before you rely on it. If you want cards from your own course material, upload it here and export the result to Anki.

Frequently asked questions

What does open source mean for flashcards?

It means the software's source code is public and can be read, changed and shared under a license. It does not change what a good card looks like, which is one clear question with one answer.

How many flashcards should I make per topic?

Most people do better with several short cards per topic than one long card. Aim for one fact per card and keep answers to a line or two.

Is DeckOwl open source?

No, DeckOwl is a hosted tool, but cards you generate can be exported to Anki on the Plus plan.

Does the free plan include exports?

No, the free plan gives you 3 generations per month and browser study only. Plus at $39/year or $7.99/month adds unlimited generations and PDF, DOCX, Anki and CSV export.
