Free tools for product teams
Browser-only utilities for visual feedback, markdown, and design QA. No signup. Built by the team behind Cobalt Capture.
Each tool is browser-only; your input never leaves the page. Built so we have something useful to hand to teammates without making them install an app. If the workflow ends in "now share this with engineering or an AI agent," the canonical version is Cobalt Capture itself.
Run a blog or docs site? Every tool above is embeddable on third-party sites with one line of HTML. Click into any tool and grab the embed snippet from the "Embed this tool on your site" link in the hero.
