The import extension comes with the app; there is no separate extension to download. It reads your library only after you request an export.

Step by step

  1. In the app, open Settings → Import → Set up Safari import.
  2. In your iPhone or iPad's Settings, go to Apps → Safari → Extensions → Capitu · Library import. Enable the extension and allow access to the Skoob domain or your chosen Amazon store.
  3. Open your Skoob bookshelf or Kindle library in a normal Safari tab and sign in.
  4. In the extension panel, tap Export to Capitu. Keep the page open without navigating away, switching apps, or locking the screen until it finishes.
  5. Save the draft in the app. Return to the Capitu app, open Imports from Safari, and review before confirming.
