Point at any UI to send exact context to your AI

Qursor is a Chrome extension that transforms how you interact with UI elements for AI-assisted development. It belongs to the category of visual inspection and context generation tools, designed specifically for developers, designers, product managers, and anyone who needs to provide precise instructions to AI coding agents. The core value lies in eliminating guesswork: instead of describing what you want changed, you point at the exact element, capture its technical details, and send that structured context to your AI. This approach saves time, reduces token waste, and ensures that AI agents act on the right code rather than interpreting vague screenshots or searching through entire codebases. By bridging the gap between visual feedback and code-level context, Qursor makes UI fixes faster and more reliable.

Before Qursor, teams often relied on screenshots or lengthy explanations to communicate UI changes, leading to misaligned interpretations and wasted AI credits. Developers would spend time searching for the right class or selector in large codebases, while designers and product managers struggled to articulate exactly what needed to change. This inefficiency meant multiple revision cycles, increased retries, and higher costs from AI token usage. Qursor solves this by allowing users to directly target the element that requires modification, automatically extracting its classes, selectors, and surrounding context. The result is a precise, actionable prompt that eliminates ambiguity and reduces the number of AI interactions needed to achieve the desired outcome. This is especially critical for teams working on tight deadlines or with limited AI budgets.

The first major feature group is exact targeting and visual inspection. When you activate Qursor on any website, hovering over an element instantly reveals its typography details (font family, size, weight, line height), color values (text, background, border), and spacing measurements (padding, margins, gaps). You can click to select the element, and Qursor displays its classes and selectors without requiring you to open browser DevTools. This feature works on production sites, staging environments, and localhost, making it versatile for all stages of development. The benefit is clear: you spend seconds understanding the element's styling and structure, rather than minutes digging through CSS files or network tabs. This speed is crucial when fixing layout issues, matching designs, or preparing context for AI agents.

Second is the annotation mode and change-aware copy. After selecting an element, you can add notes describing the exact change you want, or you can edit the styles directly within Qursor by adjusting properties like colors, sizes, or spacing. When you copy the output, Qursor includes all your edits and annotations along with the element's original classes, selectors, and surrounding HTML context. This means the exported text is a complete, structured package that an AI agent can understand immediately. You don't have to manually piece together information from multiple sources. The change-aware copy ensures that your AI has both the target and the intended modifications, drastically reducing the chance of misinterpretation and the need for follow-up clarifications. This feature alone can cut UI fix cycles from hours to minutes.
