Chorus Reader

ChorusReader turns your files, articles, and documents into
  natural-sounding audiobooks — entirely on your device.

  Drop in a PDF, EPUB, or text file. Pick a voice. Hit generate.
  Audio streams in real-time while you listen — no waiting, no
  uploading, no internet required.

  Powered by Chatterbox TTS with Apple Silicon acceleration,
  ChorusReader delivers studio-quality speech synthesis that runs
  locally on your Mac or iPhone. Your documents never leave your
  device.

  IMPORT ANYTHING
  EPUB novels, PDF textbooks, plain text, Markdown, web articles —
  ChorusReader handles them all. Smart chapter detection splits your
  content automatically. Or paste text directly.

  30 VOICES + VOICE CLONING
  Choose from 30 built-in voices (15 female, 15 male). Want something
   specific? Clone any voice from a short audio clip, or record
  yourself right in the app. Your audiobook, your voice.

  LISTEN AS IT GENERATES
  No need to wait for the full audiobook to finish. ChorusReader
  streams audio in real-time — start listening within seconds.
  Chapter navigation, speed control, and a sleep timer keep you in
  control.

  TWO GENERATION MODES
  Standard mode delivers the highest quality narration. Turbo mode
  generates up to 2x faster than real-time — a full chapter before
  you've finished your coffee.

  COMPLETELY PRIVATE
  Everything runs on-device using Apple Silicon GPU acceleration. No
  cloud processing, no accounts, no data collection. Your reading
  material stays yours.
