Notable releases 'UXLens' plugin to visualize model reasoning over prototypes

Design · 4 min read

UXLens is a plugin that visualizes an LLM's reasoning process over UI prototypes, showing which regions of a screen contributed to particular suggestions and providing justifications for each recommended change. Designers can toggle the level of explanation, view the chain of thought in condensed form, and accept or annotate suggestions before they are applied. UXLens is aimed at fostering trust and shared understanding between human designers and model outputs.

The plugin integrates with major prototyping tools and supports comment threading so teams can discuss model suggestions inline. UXLens stores provenance metadata that links suggestions to the underlying data used for reasoning, which helps design reviewers audit recommendations. The company emphasized privacy controls and the ability to host reasoning logs on-premise for sensitive projects.

Users found UXLens useful for onboarding stakeholders unfamiliar with AI assistance and for educational purposes within design teams. Some privacy advocates urged caution about storing model chains of thought, but Notable implemented access controls and redaction features. The product is being positioned as a collaborative augmentation, not an authoritative decision-maker.
