Preview AI-agent plans and reports on your Mac

Updated 21 July 2026 · 3 min read

Your coding agent just wrote a plan.md, a migration report, or a research summary. In a text editor it's raw markup; in a browser preview it leaves your machine. Here's how to read it beautifully rendered, on your Mac, in a second.

What agents hand you — and why it's awkward to read

Modern coding agents narrate their work in Markdown: a step-by-step plan before they start, a summary of what changed after, tables comparing options, code snippets, and often math or diagrams. It's the right format for the agent — plain text, versionable, structured — but reading a dense plan.md as raw source means parsing headings, pipe tables and fenced blocks in your head.

Preview it in one keystroke

Install EmDeeTool, then select the file in Finder and press Space. Quick Look renders the full document — headings, task lists, tables, syntax-highlighted code, footnotes and KaTeX math — using the same engine as the app. Close it with Space again. No IDE, no browser, no waiting.

Math, footnotes and code render cleanly — useful for research and migration reports.

Read long plans without losing the thread

Workflow tip: point your agent at a fixed path like ./plan.md and keep that file open in EmDeeTool. Every time the agent revises the plan, you get a live, readable render of its current thinking — no copy-pasting into a previewer.

FAQ

Why do AI agents write plans and reports as Markdown?

Markdown is plain text, diff-friendly and structured, so it's the natural output format for coding agents. Plans, task breakdowns, changelogs and research summaries render cleanly on GitHub and in any Markdown viewer.

How do I read a plan.md without a full editor?

Press the Space bar on the file in Finder for an instant Quick Look preview, or open it in EmDeeTool — a rendered document with headings, tables, code and math, no IDE required.

Does it render Mermaid diagrams and math?

It renders KaTeX math (inline and display) and syntax-highlighted code for every language. Mermaid diagram blocks are shown as their code, so nothing is hidden.
