Score: 6.5/10 (Innovation: 7, Technical: 7, Documentation: 7, Utility: 5)

Prism is an in-browser tool that visualizes token-level entropy (uncertainty) of a small LLM as a color-coded heatmap over user-provided text. It's interesting because it runs a 350MB model entirely client-side, providing an intuitive, interactive way to inspect model confidence without sending data to a server.

Target audience: ai-researchers, ml-engineers, data-scientists
