OpenReader: Read Aloud

OpenReader reads your EPUB books aloud and highlights each word as it is spoken, so you can listen, read along, or both.

OpenReader uses your own account with a speech service. You need an API key from one of these: OpenAI, Fish Audio, Microsoft Azure Speech, Speechify, or a server you run yourself (OpenAI-compatible or Kokoro-FastAPI).

• Word by word: the page follows the voice and marks each word as it is spoken. • Keeps reading with the screen locked, with controls on the Lock Screen. • Download chapters to listen without a connection. • Look up a word or translate a passage without leaving the page. • Pick up where you left off on another device, through WebDAV storage you own. • Your way: font, text size, margins, alignment, pauses between sentences and paragraphs, light and dark.

Free to download. Reading aloud is free for 30 days, then a one-time in-app purchase unlocks it for good. Reading, look-up and sync stay free.

No account, no subscription, no server of its own. Your documents stay on your iPhone, and text goes only to the service you choose, after you allow it. OpenReader is open source: github.com/xujialiu/OpenReader
