Show HN: An inline UX and conversion helper for developers
We've been building a tool called checkra.io to help solo developers with conversion recommendations, copywriting and UX. It's a JS snippet (script tag or npm) that adds a floating button to your site.
Click it, select any part of the page, and ask for feedback ("How can I improve conversion?", "Is this section clear?", "Accessibility issues?"). An AI (GPT-4 for now) analyzes the element + surrounding context and gives you suggestions directly overlayed on the page — even generating HTML/CSS previews for fixes.
It’s for solo devs & small teams — anyone who wants fast feedback without copy pasting HTML back and forth from the browser to the IDE and preview. It’s already caught a bunch of blind spots in own projects and we thought you'd find it interesting.
You can test it live on the checkra.io website clickable link: https://www.checkra.io/
