I built an AI memory that fact-checks itself while you sleep

The Problem AI agents forget everything between sessions. Claude Code uses MEMORY.md files - a 200-line limit, no search, no validation. After months of manually maintaining memory files, I built something better. What is BrainDB? BrainDB is a local-first AI memory system built on SQLite. No cloud, no vector database, no subscriptions. One SQLite file, 110 REST endpoints, 51 MCP tools. Why SQLite instead of Pinecone/Weaviate? SQLite with FTS5 gives you sub-millisecond full-text search with BM25 ranking.
