Verbatim persistent memory for LLM sessions. Kills cross-chat amnesia. MIT, local-first.
Overview

Cairntir

Memory-first reasoning layer for Claude Code and every other MCP client. Cairntir kills cross-chat AI amnesia — the thing where you open a fresh session and the model has forgotten every decision, trade-off, and hard-won lesson from yesterday.

What makes Cairntir different

  • Verbatim storage — nothing is summarized away. What the model wrote down, you can read back word for word, six months later.
  • Prediction-bound drawers — every claim carries a predicted outcome, observed outcome, delta, and supersedes link. Memory becomes an experiment journal, not a diary.
  • Belief-as-distribution retrieval — successful uses raise a drawer's mass, dead retrievals lower it.
  • Portable signed format — content-addressed, HMAC-signed, gossip-importable across USB, git, or any substrate.

Install

pip install cairntir

Works with Claude Code, Claude Desktop, Cursor, Windsurf, Zed, and any MCP-compatible client.
