Bitcoin Lightning Payments — No Signup, No Credit Card

No-Account AI Document Analysis

No account-linked history — from 15 sats per query

Analyze documents without creating an account. The web tool extracts text locally, so the original file stays in your browser. Sats4AI does not save the submitted text or chat result after the request completes; a model provider processes the extracted text under its own data policy. Payment and limited operational records are retained separately.

Original File Stays Local

The browser extracts document text locally. Only the extracted text and your questions are sent for model processing; no account-linked document history is created.

262K Context Window

Analyze large documents in full context. Ask questions, extract insights, summarize, compare sections — all in one session.

Multi-Turn Analysis

Upload once, ask as many questions as you want. Each follow-up builds on the previous conversation for deeper analysis.

How It Works

1

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.

2

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.

3

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.
