Echo Studio
The Windows desktop app that renders whole books into audiobook files for YouTube, Spotify, and podcast feeds. One-time license, yours forever — the demo renders any book's first chapter free.

Unlock StudioWhy the good stuff is free
Cloud TTS apps pay a server bill every minute you listen — so they sell you credits and cap your hours. Echo's voices run on your phone. Your listening costs us nothing, so we don't charge you for it.
The mission is simple: most features stay free so that people who don't have the means can still use them. Premium exists for those who want more — and to keep the lights on.
Pricing questions
Is Echo really free?
Yes. The free tier includes the full neural AI voice roster, every supported document format, and unlimited offline listening. There are no credits, character caps, or hourly meters — the free tier is the whole app, not a trial.
What does Premium add?
Premium adds the signature narrator voices Atlas and Sterling, with more premium perks planned. It costs $9.99 per month or $59.99 per year, and it is entirely optional — nothing you already use ever moves behind the paywall.
Why is the free tier so generous?
Echo was built accessibility-first: most features are free so that people who do not have the means can still use it. Because the voices run on your device instead of on cloud servers, unlimited listening costs Echo nothing extra — so there is no reason to meter you.
Are there hidden costs or usage limits?
No. Cloud TTS apps meter listening because every minute costs them server money. Echo synthesizes speech on your phone, so there is no per-hour cost to pass on. What is free today stays free.
Can I cancel Premium anytime?
Yes. Premium is billed through your Echo account on this site, and you can cancel anytime from the Manage billing button on your account page. You keep Premium until the end of the paid period, and the free tier keeps working forever.
What is Echo Studio?
Echo Studio is the Windows desktop app that renders whole books into audiobook files (M4B and MP3) for YouTube, Spotify, and podcast feeds. It is a one-time $39 license — no subscription — and the demo renders the first chapter of any book free.
