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 gives the translation only. For roots, meanings, follow-ups and Ask AI, choose BookMuse AI, Apple Intelligence (on supported devices, with Apple Intelligence turned on) or an AI provider in Bookmuse Settings → AI Engine. If you set Bookmuse up before BookMuse AI arrived, you may still be on Apple Translation.
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.
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.
