    COGNOS

    An AI cognitive operating system designed to capture raw thoughts, classify them, and map connections between ideas.

    Built with Base44AI APIsNLPGraph Architecture
    Live app

    Problem

    Notes apps store text; they do not store thinking. Ideas arrive unformed, at bad times, and the connection between two of them is usually the valuable part. COGNOS was an attempt to build a capture surface that classifies a raw thought the moment it lands and then shows how it relates to everything captured before.

    Challenges & how I solved them

    • Classification that is useful, not noisy

      Over-eager tagging made everything look connected. I constrained the label set and added a confidence threshold, so low-certainty entries stay unclassified rather than polluting the graph.

    • Meaningful edges

      Keyword overlap linked unrelated notes. Switching to embedding similarity with a minimum distance produced far fewer but far better connections.

    • Graphs that stay readable

      Past a few hundred nodes the map turned into hairball. Rendering now collapses clusters by default and expands on demand.
