I design with Claude more than Figma now

A designer at Jane Street describes how Claude has replaced Figma as his primary design tool, allowing him to rapidly prototype features directly in code rather than creating mockups and documentation. By iterating with Claude on functional prototypes that users can test, he eliminates the back-and-forth communication overhead between designers and engineers while making his ideas tangible and easier to evaluate. This shift has been enabled by improved AI models, his growing proficiency with them, and carefully scoping projects appropriately.
