Someone sent you a .md file — from GitHub, a developer, or an AI chat export — and double-clicking shows a wall of plain text. Open it here instead: rendered, readable, and private.

The fastest way to open a .md file

Drag the file into the box above (or click and choose it).
That's it — it renders immediately. No account, no upload, no "convert and download" step.

Everything runs inside your browser tab. That matters if the file is a work document, private notes, or anything you wouldn't paste into a random website: here it never leaves your device.

Where .md files come from

GitHub and code projects — READMEs, changelogs, docs. (Try the README viewer.)
AI assistants — ChatGPT, Claude, and Copilot write answers in markdown; saving one gives you an .md file. We have guides for ChatGPT exports and Claude exports.
Note apps — Obsidian, Bear, Notion, and Logseq all export .md.
