Overview / Description
Second Brain by Hexact is a local-first AI knowledge base and personal CRM that runs on your own machine and connects to Claude Desktop through MCP. You store contacts, meeting notes, business data, and other information in a personal database, and Claude can then retrieve and update that data through natural-language conversation — handling tasks like answering customer inquiries or capturing notes. Because everything stays on your device, it's aimed at users who want persistent AI memory and CRM features without sending their data to the cloud.
