Handle
Software Design and Development · 2026
Handle is a software design and development tool that brings live product design to web apps.
It connects your local repo to an AI coding agent and turns your running app into a working canvas — designers can inspect any element, edit styles directly, and route precise changes through the agent without ever leaving the product.
It ships as a macOS app (Handle Studio) and a Chrome extension.
Working in daily collaboration with the founding engineers at Tonkotsu AI, I designed Handle Studio end to end — the editing canvas, the agent chat experience, the DOM inspector, the project browser, and share flows that make AI-assisted changes feel safe to ship.
I also designed and built the marketing site at gethandle.ai, including the animated React illustrations on every feature tile.
