Echo

Read-along audiobooks from your own books — narrate locally in a cloned voice, then follow along anywhere with word-by-word highlighting.

Word-level highlightingOne clip per sentence, so timings come free — no forced aligner. Tap any line to jump there.
Your own narratorZero-shot voice cloning from a single reference clip, rendered locally on your own GPU.
Real paragraphsParagraph breaks, scene breaks and chapter titles survive extraction, so a book reads like a book.
Offline on your phoneSave a whole book to the device and play it with no connection.
EPUB exportDownload the text to read in Books or Kindle — generated from exactly what was narrated.
Figures & equationsIllustrations and maths appear inline for reference, and are never read aloud.
