Polish

Polish is an AI agent that does the job of a CRO team for founders who don't have one. Paste one snippet in your <head> (Next.js, Webflow, WordPress, Shopify or plain HTML) and it goes to work: it reads each visit (where it came from, the campaign, the device, first visit or returning), writes new headlines and calls to action in your voice and your site's language, tests them on your real traffic and serves every visitor the best version. What converts gets more traffic, what doesn't gets rewritten. Your logo, colors and layout stay yours. Every decision shows up in a plain-language feed, and you can set the voice, approve or pause anything. Measurement uses Polish's own first-party pixel, with no cookies.
