# PMB

> Local-first memory for your AI coding agent. One SQLite file on your disk. No cloud, no API keys, no re-explaining.

<Note>
  Your AI agent forgets everything between sessions. PMB remembers - locally.
</Note>

PMB gives Claude Code, Cursor, Codex and other MCP agents a real memory:
decisions, lessons, and project facts. They live in **one SQLite file on your
disk** and come back through MCP - no cloud, no API keys, no LLM call on the
read path. And it's the only agent memory that **tells you when it's actually
helping**, instead of claiming "+X%".

## What it feels like

<CodeGroup>
  ```text Without memory theme={null}
  you  ▸ fix the pricing bug from last Tuesday
  ai   ▸ which file is that in? what was the bug?
  ```

  ```text With PMB theme={null}
  you  ▸ fix the pricing bug from last Tuesday
  ai   ▸ recalled in 6ms → verdict-policy.ts:142,
         bundle fallback dropped below the 25% floor.
  ```
</CodeGroup>

The agent didn't ask. It read its memory and showed up to the task informed.
