What is an .apkg file?

An .apkg file is Anki's native deck format. You can import it directly into Anki on any device — desktop, iOS, or Android.

What input formats do you support?

We support plain text (copy-paste), PDF documents, Word documents (.docx), images of notes (including handwritten), and YouTube videos. Our AI extracts text and generates cards from any of these.

Can I edit the cards before exporting?

Yes! You can review, edit, add, or delete any generated card before downloading your .apkg file.

Yes. We process your content securely, and uploaded files are automatically deleted after processing. We never store your study materials permanently.
