The project turns your own or authorized documents into speech and portable files. It uses local TTS and word timing to export chaptered M4B, read-along HTML with embedded audio, and MP4 video.
A workflow I suggest before generating a whole book:
1. Check a short imported section against the source, especially PDF reading order and headings.
2. Generate a short passage with a built-in voice and listen for names, pronunciation and pauses.
3. Open the exported file on the intended receiving device before processing the remaining chapters.
These are suggested manual checks, not a built-in approval system or a measured user study. Optional voice cloning requires a recording you have permission to use.
The HTML sample shows the exported-player format:

Requirements: Apple silicon M1 or later, macOS 13+. Initial setup downloads engines and voice packs; daily generation runs locally. The price is $39.99 once for one Mac. The trial includes 120 synthesis minutes within 7 days of first run.
Which check would you prioritize before a long TTS job: imported text, a short audio preview, or opening the export on the receiving device?
