Captures working context, synthesizes it into a knowledge graph and profile, and feeds it back into AI tools to improve outputs.

A context engine that captures how users work, including decisions, workflows, and corrections, and synthesizes it into a personal knowledge graph and profile. It targets executives, operations, and B2B teams, particularly those using AI tools. It is delivered as a Mac-native, local-first, end-to-end encrypted application that federates knowledge among teammates with granular permissions.
