MarkUp.io is a solid visual commenting tool. But pins have no code context — and annotations have zero connection to your code.
MarkUp.io adds visual pins. Yocoolab adds visual pins WITH code context and AI that writes the fix — with AI that writes the fix.
MarkUp.io charges per project. Every additional project adds to the cost.
MarkUp.io pricing based on public plans. Accurate as of 2025.
Install the Chrome Extension. Pin feedback on your running app. Let AI handle the fixes. Free for your whole team. No credit card required.
Straight answers, including where another tool is still the better choice.
Annotation captures intent; it still leaves someone to translate that intent into a change. Yocoolab keeps the annotation attached to the real element and then routes it — with the selector, screenshot and discussion — to whoever or whatever is going to implement it, including an AI coding agent.
Yes. Multiple people can be on the same page at once with live cursors and presence, so pins and replies show up for everyone as they happen instead of being collected afterwards.
In threads tied to the project and the page, visible both in the extension on the live site and in the dashboard, with a board view for tracking what is raised, in progress and in review.
Yes, and plenty of teams should. Markup.io keeps doing what it is good at, and Yocoolab handles the part that happens on the running product — pinning feedback to a real element, keeping the discussion attached to it, and handing that context to a coding agent. Yocoolab is a browser extension, so it sits on top of your app without you migrating anything.
No. The app is free, and it stays free — including for everyone you invite to look at or comment on work. Any paid add-on in the future would be a new, optional capability, never a toll on people who just need to see the thing.
Install the browser extension, sign in, and point it at the URL you want feedback on. There is no SDK to embed and no code change to your app, so the first pinned comment usually happens within a couple of minutes.
