React Yank is a Chrome extension designed to enhance the workflow of developers by allowing them to easily yank UI elements from web pages and send this information to AI coding assistants like Cursor, Claude Code, and GitHub Copilot. This free tool includes a Quick Actions Palette for selecting the desired data, multi-select functionality for copying multiple elements simultaneously, and smart detection for various frameworks such as React, Vue, Angular, and Svelte. Additionally, it supports Tailwind CSS extraction and generates test selectors for testing libraries, making it a versatile addition to any developer's toolkit.

The extension offers practical features including a snippet library to save frequently used elements, a parent chain view for understanding the full DOM hierarchy, and network context to display API endpoints. With keyboard shortcuts for quick access and a user-friendly interface, React Yank is particularly beneficial for those engaged in AI-assisted development workflows. It prioritizes user privacy by running entirely in the browser without sending data to external servers.
