Qursor is a Chrome extension that transforms how you send UI context to AI agents by turning visual inspection into structured, code-aware data. It falls into the category of developer tools and productivity extensions, specifically for those who work with AI coding assistants like Claude or Cursor. The core value is simple: instead of uploading screenshots or describing changes in words, you point at the exact element on any live website or localhost page. Qursor captures the element's classes, selectors, styles, and any annotations you add, then lets you copy that structured context directly into your AI prompt. This means your AI agent gets exactly the information it needs to make the right change quickly. For developers, designers, and product managers, this speeds up UI fixes, reduces back-and-forth, and saves AI credits by avoiding image interpretation overhead. As a primary keyword, the UI context tool is central to its purpose, providing a direct path from visual inspection to actionable AI context.
The concrete problem Qursor solves is the inefficiency of communicating UI changes to AI. When you need a small CSS fix or adjustment, the typical workflow involves taking a screenshot, writing a description, and hoping the AI interprets the image correctly. This leads to wasted credits on image interpretation, repeated retries when the AI misses the mark, and time spent searching the entire codebase for the right selector. For teams, the pain is worse: designers send vague feedback like "make this blue", developers have to guess which element, and multiple clarification rounds delay shipping. Qursor eliminates these inefficiencies by providing exact context—the specific element's classes, surrounding DOM, computed styles, and any user-added annotations. This means fewer retries, faster fixes, and lower AI spend. The tool directly addresses the frustration of imprecise communication, making it invaluable for anyone who regularly uses AI for UI work, from solo developers to distributed product teams.
The first major feature group is precise visual inspection and targeting. When you hover over any element on a page, Qursor instantly displays essential details: font family, size, weight, line height, color values, padding, margins, and other spacing values. This eliminates the need to open DevTools or dig through CSS files for basic information. You can click to select an element, then see its exact classes and selectors. The inspection panel also supports an annotation mode, where you can add notes describing the change you want—perfect for when you do not want to edit the styles yourself. Once you are ready, the Copy button exports all this information as structured text, including any edits you made directly in the tool. This feature enables rapid design review, precise feedback, and AI-ready context without manual selector hunting, significantly reducing the time to turn a visual observation into a coded solution.

The second major feature group is component extraction and export. Qursor lets you copy entire UI components—buttons, cards, navigation bars, full sections—directly from live websites and local apps. You can export them in three formats: clean HTML, CSS, or JSX, making it easy to migrate components into your own codebase. This is especially useful for React developers who need to reuse UI patterns or for designers who want to capture the exact markup for reference. Additionally, you can download components for offline use or editing. The extraction process is point-and-click: hover to see what is included, select the component's outer boundary, and choose your export format. This eliminates the tedious work of manually recreating existing UIs, saving hours on research and prototyping. The JSX export option streamlines integration into React projects, while HTML and CSS exports are perfect for any web framework.
Beyond inspection and extraction, Qursor includes dedicated tools for colors, fonts, and assets. The color eyedropper lets you pick any color from a page—from UI elements, images, or backgrounds—and copy it in hex or other web formats. A full palette view shows the site's overall color scheme. The font detector identifies the exact font family, size, weight, line height, and letter spacing used on any text element. For assets, Qursor surfaces all SVGs, PNGs, and JPGs on a page, allowing one-click downloads or bulk export. Each tool outputs AI-ready context: you can copy color values or font details together with the element context. This means your AI agent gets the exact visual specifications it needs to implement changes accurately, without manual documentation. The color picker and font detector are particularly useful for maintaining design consistency and sending precise styling instructions to AI coding tools.
The overall workflow is designed for speed and simplicity. After installing the Chrome extension and pinning it to the toolbar, you open any website—production, staging, or localhost—and click the Qursor bubble to launch the overlay. From there, you hover over elements to inspect them, click to select, and use the toolbar to edit styles, annotate, or access specialized tools like color picker, font detector, or asset downloader. When you are ready, the copy function bundles the element context (classes, selectors, styles) with any changes you made into a single structured output. This can be pasted directly into an AI prompt or shared with a teammate. The entire process takes seconds, requires no code configuration, and works on top of any web page without altering the underlying site. This seamless workflow reduces friction between visual review and implementation, enabling faster iteration cycles.
Concrete use cases span individual developers and full teams. A developer fixing a UI bug on a live site can use Qursor to copy the exact selector and CSS, then paste it into an AI tool to generate a fix. A designer reviewing a staging site can annotate elements with change notes and send the structured context to the developer, eliminating guesswork. Product managers can gather visual feedback from clients by asking them to install Qursor, point at elements, and copy their annotations. Teams working with AI coding agents use Qursor to reduce token waste: instead of uploading screenshots, they send precise element data, resulting in fewer retries and faster implementation. The outcome is faster shipping, lower AI costs, and less frustration across design, product, and engineering. For example, a QA engineer can quickly capture the exact selector of a broken element and hand it off with a clear annotation, cutting the debugging cycle in half.
Qursor is built for frontend developers, UI designers, product managers, QA engineers, and anyone who uses AI for UI work. It runs as a Chrome extension on any website you open, including localhost. The pricing is straightforward: a free plan with 3 picks per day covering all features (color picker, font detect, assets download, component copy, annotation). For heavy users, there is a yearly plan at $29 per year or a lifetime plan at $39, both unlocking unlimited picks. The team is bootstrapped, allowing them to keep prices fair and focused on user needs. Qursor integrates seamlessly with any AI tool—Claude, Cursor, ChatGPT, etc.—by providing plain structured context that does not require special formatting. The core takeaway: it saves time, credits, and frustration by giving AI the exact UI context it needs, making the UI context tool an essential addition to any modern development workflow.
Frontend developers who fix UI bugs daily and want to reduce time spent on selector hunting and manual code searches. UI/UX designers who need to hand off precise visual feedback to developers or AI tools. Product managers who gather and communicate UI feedback from clients and stakeholders. QA engineers inspecting live sites for issues and needing exact element context. Anyone using AI coding assistants like Claude, Cursor, or ChatGPT who wants to send structured, code-aware context instead of vague screenshots or long descriptions. Teams collaborating on UI changes where clarity and speed are critical.
