Troubleshooting

My books or words aren't syncing

Make sure every device is signed in to the same Apple Account, with iCloud and iCloud Drive turned on for Bookmuse (Settings app → your name → iCloud). Large books can take a few minutes to arrive on a new device.

Translate asks to download a language

Apple Translation works offline once a language is downloaded. The first lookup in a new language pair asks to download it from Apple. If a download doesn't start, check your connection, or manage languages in the Settings app → Apps → Translate → Downloaded Languages.

I don't see word roots, meanings or Ask AI

Apple Translation, the default, gives the translation only. For roots, meanings, follow-ups and Ask AI, choose Apple Intelligence (on supported devices, with Apple Intelligence turned on) or connect an AI provider in Bookmuse Settings → AI Engine.

My AI provider or online voice isn't working

Check that your API key is valid and that your account with that service has credit, then try the Test button in Bookmuse Settings. You can switch back to Apple's built-in features at any time.

Bookmuse doesn't appear as my Translate app

Open the Settings app → Apps → Default Apps → Translation and choose Bookmuse. This needs iOS or iPadOS 26.

A book won't open

Bookmuse opens DRM-free EPUB files. Books bought from stores that add DRM can't be opened. If a DRM-free EPUB still fails, email it to us (or a link to it) and we'll take a look.

My TestFlight build expired

Each beta build works for 90 days. Open TestFlight and install the latest build. Your books and words are kept on your device and in iCloud.

How do I delete my data?

Use Erase All Data in Bookmuse Settings to delete everything on all your devices. See the privacy policy for more.
