Cairn: Event-Sourced Reasoning Graphs for AI Memory
Sonic Intelligence
The Gist
Cairn enhances AI memory by storing reasoning graphs, tracking propositions, contradictions, and confidence scores to provide context beyond simple content logs.
Explain Like I'm Five
"Imagine your brain keeps track of not just what you heard, but also what you decided was true or false, so you don't get confused later."

Impact Assessment
Cairn addresses the limitation of current AI memory systems that struggle to differentiate between settled and rejected ideas. By providing a structured reasoning graph, it enables AI to understand the context and state of thinking, leading to more informed and relevant responses.

- ● Cairn maintains a typed reasoning graph with propositions, contradictions, refinements, syntheses, and tensions.
- ● It uses confidence scores and lifecycle status to track the state of thinking.
- ● Cairn integrates with Claude Code via hooks and an MCP server.
- ● It uses local embeddings (fastembed) by default, with optional Voyage AI key for higher-quality embeddings.
Optimistic Outlook
With Cairn, AI agents can maintain a more coherent and context-aware memory, leading to improved decision-making and problem-solving capabilities. The integration with Claude Code simplifies the setup process, making it accessible to developers.
Pessimistic Outlook
Implementing and maintaining a reasoning graph adds complexity to AI systems, potentially increasing computational overhead. The reliance on specific tools like Claude Code might limit its broader applicability.
