Blubb Reader vs Local AI Reader

Blubb is a free reader for books and research papers. Import EPUB, PDF, text, and scans, then read and listen offline. For research papers with an available arXiv HTML edition, Blubb offers a formatted view that preserves equations, figures, tables, citations, and working links. Keep the original PDF at hand and change the reader's font, size, theme, and page or scrolling layout. On-device voices read aloud from your last position. Notes and highlights stay with each book. Alice's Adventures in Wonderland is included to get you started. No account, subscription, ads, or tracking. Your imported books and notes stay on your device. iCloud sync is under development and unavailable in this release.

Local AI Reader turns any document into a personal audiobook using on-device AI voices that sound remarkably natural — no internet, no cloud, no privacy concerns. Import a PDF, EPUB, TXT or RTF from your Files app, iCloud Drive or any share sheet. Local AI Reader automatically splits the text into sentences and speaks them one by one, with every word highlighted in real time as it is read aloud. Follow along, skip ahead, or tap any sentence to jump straight to it. Choose from 8 distinct voices — American English and British English, male and female — each powered by a language model that runs entirely on your device!
