How It Works
Choose Your Tool
Pick the AI tool you need from the dashboard. No account creation, no email verification, no credit card on file. Just open the tool and start using it.
Pay with Bitcoin Lightning
A Lightning invoice is generated for the exact amount in satoshis. Scan it with any Lightning wallet — Phoenix, Muun, Wallet of Satoshi, Alby, or any other. Payment confirms in under a second.
Get Your Result
Your result is delivered after payment. Sats4AI creates no account-linked usage history, but keeps transaction and limited operational or abuse-prevention records. Providers needed to run the tool process request data under their own policies.
