Second Brain by Hexact

About

Second Brain is a desktop application that runs locally, providing Claude Desktop with lasting memory via MCP. It establishes a personal database directly on your computer for storing information such as contacts, client details, meeting notes, ideas, business records, and gathered data. Claude can then access and update this database, with your consent, through everyday conversation. You can inquire about a customer and Claude will retrieve the answer from your stored files. Record a meeting and it will save the notes to your database. Search for an article, a competitor, or a past decision.
