MarkLayer

What's new in MarkLayer

By Vadym Rusin · Last updated: August 2026

Every release of the annotation tool, newest first. There is no paid tier and nothing is held back for one, so every feature on this page is in 0.7.1, the version you can install today.
0.7.1

The extension looks like itself again

Three fixes to the Chrome extension, all with the same cause: the overlay's own stylesheet was being overruled inside its shadow root, so the toolbar and every panel drew in whatever the browser fell back to rather than what MarkLayer asked for.

0.7.0

Filing into issue trackers

A thread can now become an issue without anyone leaving the page. Pick the tracker, and the annotation is filed with its text, its priority and a link back to the room — and the issue's URL comes back into the thread so everyone can find it tomorrow. Your token stays in your browser; the room never stores it.

  • File a thread into GitHub, Linear or Jira
  • Your token stays in your browser
  • Open the board with ⌘B
0.6.0

Outbound integrations, the annotation board and approvals

Feedback now leaves the page on its own: connect a room to Slack, Teams, Discord or a URL and new comments arrive where the team already works. A full-screen board sorts everything by status, and a thread finally has an ending the person who asked for the change owns.

  • Send annotations out
  • The annotation board
  • Approved
  • Present to everyone
  • Hide the chrome
  • Your name and colour in one place
0.5.0

Suggested edits, ruler guides and priorities

The largest release so far. A text selection can now carry the exact rewrite you want, ruler guides sync to everyone in the room like any other annotation, and every comment gets a priority and an owner.

  • Suggested edits
  • Ruler guides
  • Priority levels
  • Assignees
  • The eraser reaches everything
  • Hold Shift to constrain
  • Voice and video controls
  • Zoom presets in the web viewer
  • A public share API
0.4.0

The MCP server, area and multi-inspect

Annotation stopped being something you only send to a person. The MCP server hands a room straight to a coding agent, which reads the comments, works through them and marks each one done while you watch it happen.

  • The MCP server
  • Area tool
  • Multi-inspect
  • Quick grab
  • Share dialog
  • Settings panel
  • Measure in the web viewer
0.3.0

Inspector and Measure

Two tools that turn "this looks off" into something a developer can act on: what the element actually is, and how far it sits from the thing beside it.

  • Element inspector
  • Measure
  • Rearrange the toolbar
0.2.3

Toolbar polish

Two small patches to the toolbar: it collapses out of your way, and it arrives and leaves with a fade instead of a jump.

  • Minimize the toolbar
0.2.1

Text, Markdown export and multi-page projects

The first version of the inspector, a text tool, and a way to keep a whole site review under one link instead of one link per page.

  • Element inspector
  • Text annotations
  • Markdown export
  • Multi-page projects
0.2.0

Themes and narrower permissions

A theme that follows your system, a presence indicator that says something, and an extension that asks for far less than it used to.

  • Light, dark and system themes
0.1.0

First release

The first public version: draw on any webpage, pin comments to it, and send one link that anyone can open without installing anything or creating an account.

  • Drawing tools
  • Threaded comments
  • Real-time collaboration
  • Shareable links
  • PNG export
