AI EPUB Reader: Chat with Ebooks and Get Instant Summaries
EPUB is the universal format for ebooks — used by virtually every ebook store, digital library, and academic publisher outside of Amazon’s ecosystem. Yet when it comes to AI document tools, EPUB is almost universally ignored. ChatPDF, NotebookLM, Humata, PDF.ai — none of them support EPUB files. LocalRAG is different: it’s one of the only AI document tools that lets you chat with EPUB ebooks, right on your phone.
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 likely have a library of EPUB files. These might be purchased ebooks, library loans, open-access textbooks, or digital editions from academic publishers. When you want to use AI to summarize chapters, answer questions, or extract key information, you hit a wall: almost no AI document tool supports EPUB. Your options are limited to converting EPUBs to PDF (which often breaks formatting) or manually copying text into a chatbot.
How LocalRAG reads your EPUBs
LocalRAG natively supports EPUB format alongside PDF, DOCX, and 6 other document types. Import an EPUB ebook, and LocalRAG extracts and indexes all the text on your device. Then ask questions, request summaries, or explore the content through natural language — just like you would with a PDF. Everything is processed on-device, so your ebook library stays private.
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.
Chat with your ebook
Ask questions like “Summarize chapter 3” or “What does the author say about X?” and get AI-powered answers with references.
