What makes it different
Closes the gap between fast AI coding and understanding real user needs
Captures context that prevents silent churn
One-command setup with no configuration needed
Brings user testing into the product without dedicated QA
Turns scattered user requests into obvious product priorities
Every status check is signed and publicly logged so verification is cryptographic, not based on trust in the company
Catches silent payment address or network changes that would otherwise go unnoticed
Free connection with no sign-up, plus pay-per-call options for flexible scaling
Works across multiple AI agent frameworks (Claude, Cursor, VS Code, Gemini, ChatGPT) via standardized MCP protocol
Local agent signing tool keeps private keys on the user's machine, never uploaded to servers
