cairn

Cairn provides persistent memory for Claude Code, enabling invisible self-annotating metadata and semantic search capabilities. It facilitates cross-project retrieval and acts as a developer tool for managing code-related information. The agent leverages embeddings and vector search to enhance code understanding and accessibility. Developers working with Claude Code can use Cairn to improve their workflow and access relevant information more efficiently. It supports a local-first approach and utilizes SQLite for data storage.

Cairn solves the problem of managing and retrieving information across multiple code projects when using Claude Code. Manually searching and annotating code can be time-consuming and inefficient, and Cairn automates this process with persistent memory and semantic search.
