What It Does
Cairn provides a persistent reasoning graph that maintains the cognitive structure of decisions made during conversations. It captures propositions, contradictions, and the lifecycle status of discussions, allowing AIs to access this structured thinking rather than a flat log of past exchanges.
Who It's For
- •Developers
- •AI researchers
- •Teams using AI for decision-making
Why It Matters
By organizing cognitive events into a structured graph, Cairn enables AIs to understand the context of decisions, which enhances their ability to assist in future discussions. This helps avoid confusion over past decisions and improves collaborative accuracy.
What Makes It Different
Cairn's reasoning graph differentiates it from conventional AI memory by tracking the state of thinking rather than just storing past statements.
