Qursor

In plain words

Qursor is a browser tool that helps developers and AI agents communicate about UI elements more precisely. Users point at any element on a webpage to extract structured information including selectors, classes, styles, fonts, and colors, then copy this data to paste into AI agents. The tool includes a color picker, font detector, and can extract components as HTML, CSS, or JSX code. It's designed to reduce token waste and mistakes when using AI to edit website interfaces.

I kept wasting AI tokens describing UI changes to agents that edited the wrong element. So I built Qursor. Point at any element, copy structured context (selectors, classes, styles, fonts, colors), paste into your AI agent. No vague screenshots. No burned credits. - Inspect fonts, colors, spacing - Copy AI-ready element context - Extract components as HTML/CSS/JSX - Color picker and font detector - Download assets from any page

Qursor is the Chrome extension that lets you inspect any website visually, point at exact UI elements, and copy clean, structured code-aware context for your AI coding assistant.

Qursor turns UI annotations into structured, code-aware context your agent can actually use. You point to the exact element and send the exact classes, selectors, and context needed. Instead of uploading screenshots, wasting credits on image interpretation, or forcing AI to search the whole codebase for one small change, your agent can fix it fast. Qursor gives AI the exact UI context it needs to act fast. No vague screenshots, no long explanations, and no wasted tokens trying to locate one small change in a large codebase. Hover any element to instantly see the essentials like fonts, colors, spacing, padding, and margins. Click to edit styles directly or annotate what should change, then…from qursor.xyz

  Hello, My name is Yahia, I've been working on scraping products for a long time and maintain a couple of free sites in my spare time (E.g. knifegeek.io) What prompted this is i've rebuilt scraping infra at every company I've started and finally just made it a product. Pass a URL, get clean markdown, html, images, sitemap or pass a domain, get logos, colors, socials, industry data. Goal is to offer a better service than VC funded competitors at a fraction of the cost. Stealth is included and automatic at no additional cost (normally an upcharge by alternatives). Would love your honest thoughts.

The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

  Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
