Anytime Markdown Editor

日本語 | English

Rich preview of AI-generated Markdown while you code — all inside VS Code.

AI assistants write specs, designs, and notes in Markdown, but reviewing plain text is hard to read and switching between tools breaks your flow.

Anytime Markdown gives you a WYSIWYG editor with rich rendering, plus collaborative editing with AI to prevent file conflicts.

1. What You Can Do

• Rich Markdown editing — render tables, Mermaid, PlantUML, and KaTeX inline
• Auto-lock while AI is editing — prevent conflicts when Claude Code is writing to a file
• AI change highlight in gutter — visually mark edited blocks in the gutter when Claude Code modifies the file
• Switch between 3 modes with one click — WYSIWYG, Source, Review

2. Getting Started

Right-click a .md / .markdown file and choose "Open with Anytime Markdown" to open it in the editor.

Available from both the Explorer context menu and the editor title bar context menu.

3. Auto-Lock While AI Is Editing (Claude Code Collaborative Editing)

While Claude Code is editing a file, the editor becomes read-only to prevent conflicts.
When editing finishes, the lock is released and the content is updated automatically.

• Anytime Trail required — Trail registers the Claude Code hooks; this extension reads the status to control locking
• Handles rapid edits — lock is released 3 seconds after the last edit
• Crash safe — auto-unlocks after 30 seconds if Claude Code stops responding

4. AI Change Highlight Review

When Claude Code edits a file and the editor auto-reloads, changed and added blocks are marked in the gutter on the left side of the editor.
See at a glance what was rewritten, then press Escape to clear the markers.

• Added / changed blocks — change marker shown in gutter
• Deleted sections — deletion indicator shown at the position of removal
• Only active when auto-reload is enabled

5. Editor Modes

Switch with the mode menu in the toolbar.
