Julien Thibeaut

Design Engineer

Building software with a focus on design, detail, and function.

I run Interface Office, a design-engineering studio building products, tools, and interfaces for AI teams.

Some of my work:

  • UI Skills – opinionated constraints for building better interfaces with agents
  • Anatomy of AI Input - understanding the structure of an AI input
  • AI Glossary – interactive guide to core concepts of artificial intelligence
  • prompt-kit – components for AI interfaces
  • zola – open-source chat app
  • motion-primitives – library of animated components
  • lab – archived prototypes and interface studies

I share notes and updates on X, and open-source code on GitHub.

I curate playlists every month and run every day.
