PinCushion is a Chrome add-on designed to enhance collaboration by enabling users to drop visual feedback pins on any web page. It allows teams to leave comments directly on live or staging sites, capturing essential context like CSS selectors, DOM snapshots, and screenshots automatically. This eliminates the need for lengthy email exchanges or confusing screenshots, streamlining the communication process between stakeholders and developers.

The tool integrates with AI agents via the MCP protocol, allowing for efficient implementation of fixes without the back-and-forth typically associated with feedback. Key features include threaded comments for in-context discussions, real-time sync for team updates, and a pricing model that offers a free tier for stakeholders. PinCushion is ideal for web agencies, QA teams, and freelancers looking to simplify their feedback process.
