AI EPUB Reader: Chat With Ebooks and Verify the Source
Yes, AI can read EPUB files. LocalRAG! imports DRM-free EPUB ebooks directly, builds the search index on your phone or tablet, and lets you ask questions, summarize chapters, and return to the cited passage. Use the local AI for an offline workflow, or choose Claude when you want higher accuracy; in Claude mode, only your question and the retrieved excerpts are sent to the API, never the original ebook file.
The EPUB gap in AI document tools
If you’re an avid reader, a student using digital textbooks, or a researcher working with academic publications, you may have a library split across EPUBs, PDFs, notes, and scanned pages. Converting an EPUB to PDF can damage chapter structure and formatting, while copying passages into a general chatbot removes the surrounding context and makes sources harder to verify.
How LocalRAG! reads your EPUBs
LocalRAG! supports EPUB as part of 25 formats across documents, images, audio, and video. Import a DRM-free ebook and the app extracts and indexes its text on your device. You can then ask questions, request summaries, or search across the EPUB and other files in the same collection. Answers include source references so you can return to the relevant passage.
Import your EPUB
Open any EPUB file from the Files app, iCloud Drive, or your ebook app. DRM-free EPUBs from any source are supported.
Automatic text extraction
LocalRAG! extracts all text from the EPUB’s chapters, preserving structure. Indexing happens entirely on your device.
