Marklet is a native Markdown workspace for macOS — built for the age of AI-generated content
Marklet is a native Markdown workspace for macOS — built for the age of AI-generated content.
If you use AI seriously, you know the problem. Your tools produce beautiful, structured Markdown. It lands in your folder. And then you squint at it in a text editor, preview it on GitHub, or copy it somewhere just to read it properly.
Marklet fixes that. Open a folder. Click a file. Read beautifully.

FITS NATURALLY INTO AI WORKFLOWS
Keep your AI tool on one side. Marklet on the other. Generate with Claude, ChatGPT, or any AI — Marklet renders the output instantly. Your files never leave your Mac.
