Every word,
echoed back.
Turn any document, article, or URL into a natural-sounding audiobook. Powered by an on-device Kokoro voice engine tuned for long-form listening.
Everything you need to listen
A complete listening toolkit, built around an on-device voice engine tuned for hours, not demos.
Kokoro Voice Engine
An on-device neural voice engine rebuilt around hours-long listening, not short demo clips. Pronunciation, prosody, pacing, and voice character are all tuned for real books.
Any Document, Any Article
Read PDF, EPUB, DOCX, RTF, plain text, Markdown, and HTML. Paste any web URL and Echo extracts just the article. Share text or links from any other app.
Pronunciation You Can Teach
A deep pronunciation layer handles fantasy names, loanwords, technical jargon, and words whose meaning changes how they sound. Anything it still misses, you fix once — forever.
Community Library
Browse and submit shared audiobooks, follow author profiles, leave star ratings and likes, and read author updates as they ship.
Full-Screen Reader
Word-level highlighting synced to the audio, bookmarks, chapter navigation, and automatic resume. Read along or just listen — your choice.
Voice Mixer and Presets
Blend any two voices into a custom narrator, or pick from curated character and accent presets. Enunciation and pacing are exposed as knobs, not hidden defaults.
Three steps to your audiobook
From any document, article, or URL to natural narration in minutes. No recording studio required.
Bring Your Text
Import a document, paste a URL, or share text from any other app on your phone.
Pick Your Voice
Choose a preset, blend a custom voice in the mixer, and dial in pacing and enunciation.
Listen Anywhere
Full-screen, background, or with a sleep timer — with or without an internet connection.
