L&N Reader vs Local AI Reader

Lectures and Narrations — a player for enhanced, multi-voice .m4b audiobooks on iPhone and iPad, with an EPUB companion reader that highlights the text in sync with the narration. PLAYER • Chapter-relative scrubbing with a whole-book progress strip and live time remaining. • ±10/30 s skips, previous/next chapter, tappable chapter list. • Pitch-preserving 0.5×–3× speed, remembered across launches. • Background playback with full lock screen and Control Center support. • Mini-player on every screen — skips, chapter and book progress, and a Read shortcut. • Auto-saves your position and resumes where you left off. CAST ANYWHERE • AirPlay and Google Cast, side by side — stream to any speaker or TV while the sleep timer, reader sync, and progress saving keep working. READER + SYNC • Attach the matching EPUB and a sync manifest, and the text highlights itself in sync with the audio, scrolling and turning pages as you listen. • Manual paging pauses following; Resume jumps back to the narrated line. • Whole-book text search with in-place highlighting. • Light/dark mode and adjustable text size, both remembered. LIBRARY • Import .m4b audiobooks from the Files app — or AirDrop a book to your device and it imports itself. • Covers with progress bars; folder-style collections you can arrange by hand. • Finish a book in a collection and the next one is offered by its cover. IMAGES • Every illustration embedded in the audiobook, in a gallery with pinch zoom — and as tappable markers on the player scrubber. SLEEP TIMER • By time or by chapters, with volume fade-out, postpone, and shake-to-postpone. ONE ECOSYSTEM, TWO HALVES LN began as an AI experiment in book understanding — using language models to analyze narrative structure, character traits, and scene dynamics — and grew into an end-to-end pipeline for immersive, multi-voice audiobooks. ln-vox, the creator: an offline, self-hosted AI pipeline that ingests raw text or EPUBs, orchestrates LLMs to cast characters and direct emotional delivery, then uses local TTS to generate a fully acted, multi-voice .m4b complete with text-to-audio sync markers. ln-reader, the consumer: this app — built specifically to play those enhanced audiobooks.

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!
