Qursor

Qursor is a visual feedback tool that turns your on‑screen UI annotations into structured context that AI coding agents can understand and act on.

Instead of describing "the blue button in the sidebar," you click the exact element, add a note, and Qursor generates rich, formatted output your AI agent can immediately use. No screenshots, no vague descriptions, no wasted tokens.
With Qursor active, you can hover over UI elements to see their names, click to annotate them, then copy the generated markdown into tools like Claude Code, Cursor, or any AI assistant connected to your codebase.

A single screenshot can cost 1,000–2,000+ tokens on its own, and a vague description often takes 3–4 follow-up exchanges before an agent even finds the right file. Qursor replaces both with a compact markdown block (exact selector, file path, and line number), so the agent acts in one shot, with no searching, no guessing, and no extra round-trips.
The output includes:

- CSS selectors so agents can grep your codebase directly
- Source file paths and line numbers to jump straight to the right code
- Computed styles so the agent understands current appearance
- Your written feedback, including intent and priority

Inspector feature
Qursor also works as a lightweight design and code inspector for any live website: pick colors from any pixel, detect fonts, download assets in original quality, and copy real HTML, CSS, or JSX for any selected element or section.
