I design with Claude more than Figma now (blog.janestreet.com) AI

Edwin Morris of Jane Street says he now uses Claude more than Figma by writing a problem description, prompting Claude in an editor to rapidly build and iterate working prototypes in the real codebase, and then collecting user feedback—shifting effort from mockups and spec docs to functional artifacts. He notes benefits like fast, unlimited iteration on features (e.g., adding LLM prompting to an internal SQL input) and easier evaluation by engineers and users, while also acknowledging downsides such as reviewers receiving “fully baked” code and a concern that the workflow may limit more open-ended creativity for novel problems.
