The website commenting tool for live pages
PageProofer is a website comments tool that works right on your live site. It’s like adding sticky notes to your website, only better. Whenever you notice an issue, click it and leave a comment. The comment is pinned to that exact element, and you can attach a screenshot and a quick drawing to make the point.
Pin comments on live pages: the human review after your AI agent builds
Coding agents now build much of the web, and they reliably miss what only shows up in a real browser: spacing and alignment that’s slightly off, links and buttons that don’t click properly, hover and focus states, overlapping elements, animations that aren’t polished and layouts that break at certain screen sizes. A person spots these in seconds.
- The agent builds or changes the site.
- A person reviews the live site and pins comments in PageProofer, right on the elements that need work.
- PageProofer’s hosted MCP server hands each comment, with the element’s CSS selector and HTML, a screenshot, browser and device info and any console errors, to Claude Code or Cursor to fix.
- The person checks the fix on the live site.

Comment on a web page in 3 clicks
It’s simple. After you add PageProofer to your website, click the icon and then click anywhere to leave a comment. The comment gets pinned to the element you clicked on, like a sticky note.
You can attach a file, a screenshot or even a screen recording. Inside each comment thread you can talk it through with your team and assign it to someone if action needs to be taken.
Say hello to fast and easy website commenting.
Commenting, annotating or marking up a website: same job
Whether you call it a website commenting tool, a website annotation tool or a website markup tool, the job is the same: point at something on a live page and say what needs to change. PageProofer does all three, with every comment pinned in place and the technical details captured for you.
1. Spot an issue
A broken image, a typo, a button that doesn't work. When something on your website looks wrong, you don't need to take a screenshot, write an email and try to describe where it is.
2. Add a note
Click the PageProofer icon, click the problem and type. The note is pinned to that exact element, and a screenshot, the browser and screen size, and any console errors are attached for you.
3. Get it resolved
Assign the note to someone on your team and talk it through in the comments. Or hand it to an AI coding agent: with our MCP server, agents like Claude Code and Cursor read the note, fix the code and reply, so a person can check the fix.
I cannot imagine managing all of our project edits without PageProofer
