Why a browser-based Anki flashcard app can save setup time

Anyone who has used Anki knows the hard part is writing clear cards, not installing software. If you want an Anki flashcard app that builds those cards from your own material, DeckOwl runs in the browser, so there is nothing to download to start.

  • Works in any modern browser, so no installer is needed to start
  • Generates flashcards from PDFs, slides, notes and photos of pages
  • Uses spaced repetition to schedule reviews
  • Exports to Anki and other formats on the Plus plan

Frequently asked questions

Do I need to download anything to use DeckOwl?

No. The free plan runs in your browser, and you can start without a credit card. Exporting to Anki requires the Plus plan.

Can I export my flashcards to Anki?

Yes, on the Plus plan at $39/year or $7.99/month. The free plan includes browser study but no exports.

How many flashcards should I make per lecture?

Aim for one card per distinct fact, term or relationship, which usually means a few dozen for a dense lecture. Cut any card that tests something you can't yet explain.

Should I study flashcards in long sessions or short ones?

Short, frequent sessions work better than one long cram, because spaced repetition brings each card back just before you would forget it. Fifteen to twenty minutes a day is a practical starting point.
