free markdown extension
A WYSIWYG editor, kanban boards, and file viewers for product managers, writers, and anyone who lives in docs.
For VS Code, Cursor, Windsurf, Antigravity, and other VS Code editors.
features
You see headings, tables, and checkboxes while you write. The file on disk is still markdown, so git, pull requests, and AI agents work with it like before.
slash commands
One key opens every block and template. No toolbar hunting and no markdown syntax to remember.
ai change tracking
When an AI agent edits your doc, every change is highlighted right in the formatted page. Review it like a tracked-changes doc.
kanban boards
Plan a launch on a real board. Each column is a heading and each card is a checkbox, so the board lives in your repo next to the spec.
comments
Leave comments on the exact sentence that needs work, and see every thread in one panel.
rich blocks
Everything a good PRD needs renders inline as you write, from a decision table to a flowchart.
and more
Type [[ to link any note in your workspace, with search as you type.
A slim rail of headings that jumps you around long docs.
Cmd+F and Cmd+H, in docs and on boards.
Frontmatter shown as tidy, typed fields at the top of the doc.
Save any doc as PDF, HTML, or clean markdown.
Paste or drop an image. It is saved to your attachments folder and linked.
Hebrew, Arabic, and Persian docs read the right way, detected automatically.
Select text and send it to your AI chat with its file and line context.
built-in viewers
Read the brief, check the roadmap, and sort the feedback in the same window as your docs.
Zoom and page through briefs and contracts.
Read .docx files with their formatting.
Browse every sheet with tabs.
Sort any column with a click.
for product managers
Write PRDs, specs, and roadmaps in the same repo as the code. Engineers review them in pull requests, and AI agents read the spec you actually wrote, not a copy pasted from another tool.
