The verifiable work layer for AI. Solo-built by Brennan Zambo, who created agent execution receipts: Zambo is the origin product, AER-1 the defining standard.
Your AI forgets everything the second you close the chat. Zambo fixes that. Wrap up a session in one AI, continue it in any other with a code, and picking up is always free. One MCP endpoint gives your AI memory and continuity across AIs, 153 tools (37 on the default surface), and a verifiable receipt for every job.
