An LLM can do most of what this tool's UI promises. No moat, no agent presence.
“showmd is a native macOS Quick Look extension that does one thing well: preview Markdown files locally. But that thing is entirely replaceable. An LLM can render Markdown, parse YAML, and toggle views in a browser or native app. The only defensibility is that it's a Quick Look plugin — a macOS-specific integration point — but that's a narrow moat that dies the moment Apple ships native Markdown preview or a better competitor builds the same plugin. This will be replaced.”

- Toggle between rendered and source views
- Apply dark mode styling to previews

How to defend
Become the Markdown preview layer that agents and IDEs call, not a standalone viewer. Ship as a VS Code extension, Obsidian plugin, and CLI tool that syncs preview state across devices. Own the Markdown-to-web-share workflow — let users publish previews with one click and build a small network effect around shared Markdown documents.
- Ship an MCP server and list it on Stork — biggest single point gain (+25).
- Get listed in the Anthropic MCP registry, Cursor, or Claude Desktop (+20).
- Add a usage-based or per-call tier; per-seat-only pricing dies when agents replace seats (+15).
- Expose API-key auth with a self-serve sandbox tier; remove sales-call gates (+15).
- Publish an OpenAPI spec at /openapi.json or /.well-known/openapi (+10).
