How to Convert Text to Speech with Bitcoin Lightning
17 voices. 40+ languages. Emotional expression. No signup. 300 sats per generation.
Why Use Sats4AI for Text to Speech?
Quality text-to-speech services charge $5-33/month for subscriptions with character limits. Cloud alternatives require developer accounts, billing setup, and API key management before you can generate a single word. Free tools exist, but they sound robotic and aren't usable for anything professional.
All of them require you to create an account — email, password, credit card. That's personal data sitting in someone else's system, one breach away from being exposed. And you end up paying for a full month when you only needed one voiceover.
With Sats4AI, there's nothing to sign up for. Type your text, pick a voice, pay 300 sats (~$0.30) via Lightning, and download your audio file. We don't know who you are and we don't store anything about you.
