MarkLayer
Website feedback your AI agent can act on.
Draw, highlight, and comment on any live webpage, then share one link. A human reviews it in real time, or an AI agent connects over MCP and works it like a to-do list: acknowledge, fix, resolve, reply.

One URL. A shared board. A faster decision.
MarkLayer turns any webpage into a collaborative review surface. Instead of passing screenshots back and forth, send a link. Teammates or clients can open the original page in their own browser, leave feedback where it belongs, and see changes land live. So can an AI agent: each comment arrives with the exact element it refers to already attached.
- For AI-assisted work: connect marklayer-mcp and hand an agent a live queue of annotations to acknowledge, fix, and resolve. Or inspect an element yourself for a stable selector and an AI-ready markdown snapshot.
- For client feedback: let clients point to exactly what they mean, without an account or extension.
- For design review: sketch ideas, highlight details, and keep the conversation attached to the page.
- For QA: pin reproducible issues to the actual UI, then share a clean link with the team.
How it works
- Open a page: paste any public URL at marklayer.app, or use the Chrome extension on the page you are already viewing — including a page on your own localhost dev server, which never has to be reachable from the internet.
- Make the feedback visible: draw, highlight text, measure space, pin a threaded comment, or inspect an element.
- Share one link: collaborators join the same board and see cursors, marks, replies, and calls in real time. Point an AI agent at it instead, and marklayer-mcp turns the thread into a work queue.
No sign-up. No trial clock. No client install.
