PMB supplies persistent local memory for AI agents through an owned SQLite database.

PMB maintains a single local database that records agent activity automatically through hooks. These hooks classify incoming messages and retrieve matching entries from the memory store in milliseconds, allowing the agent to reference prior context without explicit calls. The system also logs new outcomes after each turn to build an evolving record of project details. A visual dashboard presents the stored information as an interactive entity graph and chronological journal. Users can explore connections between facts, decisions, and lessons while the underlying hybrid retrieval combines keyword, vector, and graph methods to rank results. Lessons receive ongoing evaluation based on actual usage patterns to keep the memory relevant and concise. Integration requires a single setup command that links supported agents to the shared memory workspace. Once connected, multiple tools access the same records, enabling seamless transitions between environments while preserving full offline operation and user control over all data.
Keep decisions, lessons, and project facts in a single local SQLite file so every new agent session starts with full awareness of prior work without re-explaining context.
Use the same memory store across multiple coding agents so switching between tools carries context automatically without manual copying.
Track which lessons agents actually follow and automatically flag or remove low-value entries to keep the memory store accurate and compact.

Our take: PMB | Local-first memory for AI is a solid productivity choice. It's valued for 100% offline with no api keys or cloud and sub-35 ms recall and sub-millisecond writes. The main trade-off is requires local installation and mcp wiring. A good pick if you want capable AI without a high upfront cost.
All memory lives in one SQLite file on your local disk that you fully own and control.
