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
- In the app, open Settings → Import → Set up Safari import.
- 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.
- Open your Skoob bookshelf or Kindle library in a normal Safari tab and sign in.
- In the extension panel, tap Export to Capitu. Keep the page open without navigating away, switching apps, or locking the screen until it finishes.
- Save the draft in the app. Return to the Capitu app, open Imports from Safari, and review before confirming.
