Bastra Recall

What is Bastra Recall?

Bastra Recall is a persistent memory layer that works across multiple AI surfaces — Claude, ChatGPT, Cursor, and any tool that speaks MCP or HTTP. It runs as a single local daemon serving all AI tools at once, storing memories as plain markdown files with YAML frontmatter in an Obsidian-compatible vault.

How to use Bastra Recall?

Install the daemon locally and point it to a vault folder of markdown files. The server autonomously saves learned information and recalls relevant memories before actions via hooks like PreToolUse and SessionStart (Claude Code). No manual configuration steps beyond setup are described in the README.
