About mdstudio
mdstudio is a minimal, fast markdown editor and viewer. There's no account to create, no backend, and nothing to install — paste or drop a markdown file and it renders instantly.
Why it works this way
Everything runs in your browser. Documents live in localStorage, and — if you use the “Open a local folder” option — directly on your own filesystem via the File System Access API, with edits saved straight back to disk. Nothing is uploaded anywhere, because there's nowhere for it to go.
What it can do
- Edit / Split / Preview, Zen, Focus, and Presentation modes
- GFM markdown, math (KaTeX), and Mermaid diagrams
- A customizable look — fonts, accent color, width, spacing, code theme
- Local folder sync, drag-and-drop import, and export to Markdown/HTML/PDF
- Shareable links that encode a document straight into the URL
