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 0.5.0, the version you can install today.
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
