Which files can Reader open?
Reader opens PDF, EPUB, and plain text files. Rendering and annotation capabilities vary by format.
Can I read offline?
Yes. Managed local books, reading positions, search, highlights, and notes are designed to keep working when the backend is unavailable.
Why is my book not available to AI?
The book may still be preparing, may be local only, or may have rights or technical limits that prevent cloud processing. Local reading should remain available.
How do I delete my account?
Open Reader's account surface and choose Delete Account. This removes the account and its associated private Reader storage, subject to short-lived backups and legal requirements.
