Skisso

Skisso is a browser extension that lets users visually select and edit interface elements on a live page to generate diff patches for AI coding agents.

Skisso is a browser extension designed for developers and designers working alongside AI coding agents. Users select live webpage elements such as buttons, cards, text, or sections, and edit their spacing, colour, type, layout, and copy directly using real CSS. Rather than generating prose descriptions or screenshots, the tool converts the modifications into a structured diff containing the element address, original values, and updated values. Users can then copy this patch and hand it directly to their coding agent in the terminal. It works across localhost, staging environments, and live websites.
