Second Brain is a local desktop app that gives Claude Desktop persistent memory through MCP. It creates a personal database on your machine where you store contacts, customers, meeting notes, ideas, business data and scraped data. Then Claude reads and writes to it, with your permission, through normal conversation.
Ask Claude about a customer and it pulls the answer from your records. Log a meeting and it saves the notes to your database. Look up an article, a competitor, a decision.
Redis, MongoDB, and PostgreSQL monitoring in one browser UI: live metrics, alert thresholds, Slack, Telegram & webhooks, data browsing, TLS, and owner/admin/member roles. Self-host or use our cloud.
