How the flashcards work
Free and unlimited at the core — bring cards, review minutes a day, take them anywhere.
Bring your cards
Import Anki .apkg, CSV, Excel or a full backup — or photograph a word list or book page and approve the cards AI drafts from it.
Review minutes a day
The FSRS scheduler picks what is due; every grading button shows the next interval, and five per-deck presets run from relaxed to intensive.
Make cards rich
A full editor with formatting and per-side languages; images from camera, clipboard, upload or AI; audio from TTS, your microphone or a file.
Take them anywhere
The web and mobile apps run the same scheduler, and your collection syncs through your own private Google Drive folder with daily recovery points.
Frequently asked questions
Which parts use AI Units?
Only the AI helpers — generated images and audio, photo and word-list import, the card analyser and bulk deck media. Decks, cards, reviews, import, export, statistics and sync stay free and unlimited.
Can I move my collection from Anki?
Yes — .apkg import reads all three generations of Anki files, including the modern compressed one, with your deck tree and media, and shows a preview before anything is written.
What is FSRS?
A modern spaced-repetition scheduler that adapts to how you actually remember. The presets cover most people; advanced settings expose target retention, intervals and even the raw weights.
Does it connect to the rest of Oropen?
Everywhere — a dictionary lookup becomes a card in one tap, games draw today's due cards and count as reviews, and the speaking teacher can weave your words into lessons.
