Qursor: A browser tool that copies structured UI element context for AI agents
By
Omkar Birje
Summary
Qursor is a browser tool that lets users point at any UI element on a website and copy structured, code-aware context (selectors, classes, styles, fonts, colors) directly to their clipboard. It was built to solve the frustration of wasting AI tokens trying to describe UI elements to AI agents, replacing vague screenshots with precise, structured data. Features include font/color/spacing inspection, AI-ready element context extraction, component extraction as HTML/CSS/JSX, a color picker, font detector, and asset downloading.

Screenshots helped a little, but agents still had to interpret them, wasting tokens and time.
It lets you point at any element on any website, and it copies structured, code-aware context, selectors, classes, styles, fonts, and colors directly into your clipboard.
