Cobalt Capture
Visual feedback. No install, no signup. Free.

Cobalt Capture is a browser-based visual feedback tool that lets users capture screenshots, add typed or dictated commentary, and publish a shareable review as a public URL, markdown, PDF, or Word document. It requires no installation, browser extension, or signup to use. The output is designed to be readable by both humans and AI coding agents like Cursor, Claude Code, and others.
Users capture a screen in their browser, add typed or dictated commentary per screenshot, then hit Publish to get a public URL and clean markdown export that can be pasted into an AI agent's prompt or committed to a repo.
