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.

Try MarkLayer · Add to Chrome · Connect an agent · Build from source

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: give an agent the share link over MCP and it works the annotations as a live queue: acknowledge, fix, resolve. Nothing to install. 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 the same link over MCP instead, and the thread becomes its work queue.

No sign-up. No trial clock. No client install.

What you can do


Send an agent to work the page	Every share link is also a remote MCP server, so an AI agent can watch annotations and acknowledge, fix, and resolve them live, or review the page and leave notes of its own.
Annotate freely	Pen, highlighter, eraser, shapes, arrows, text, and text-selection highlights.
Keep feedback in context	Pin threaded comments to the page, reply inline, and track status.
Review live	Real-time cursors, drawings, and c
