Overview: import vs sync

Acorny has three current ways to bring highlights into your library: a one-time file or API import, a connected service that keeps syncing, or a reader app that sends highlights with an Acorny Import API token.

  • Moving an existing library once: use a file import or a one-time API import.
  • Receiving new highlights from a connected service: connect Instapaper or Inoreader in Extensions & Apps.
  • Sending highlights from a reader app: create an Import API token in Acorny Settings, then configure the reader’s Readwise-compatible sync.

A one-time import copies the highlights available in the selected file or API response. Use it for migrations, restores, and occasional transfers. Repeating an import is not the same as keeping a provider connected.

Instapaper and Inoreader appear as connection cards in Extensions & Apps. After setup, use Manual sync when you need to request a sync outside the normal connected flow.

Koodo Reader, Moon+ Reader, and Readest are configured inside the reader app. Create an Import API token in Acorny Settings and paste the documented URL and token into that app’s Readwise integration settings. These reader apps do not appear as connected provider cards in Acorny.

Open your library and confirm the expected source and highlight text are present. If an import or connection does not complete, use Import and sync troubleshooting. When the content is ready, continue with How review sessions work.
