ChatGPT gave me a .md file. Now what?

If you've used ChatGPT, Claude, or Gemini for anything longer than a tweet, you've probably ended up with a file called something like draft.md on your computer. You double-click it. Your laptop either asks which app to open it with, or it opens in Notepad / TextEdit and you see a wall of plain text with hash marks and asterisks. Definitely not the nicely formatted thing ChatGPT showed you in its reply.

This post answers the three questions everyone asks at this point, in plain language, with no developer jargon: what is a .md file, why does your laptop show it as raw text, and what's the fastest way to actually read or share it.

What is a .md file?

.md is the file extension for Markdown. Markdown is a way of writing formatted text using just plain typewriter characters. You write # Heading and a Markdown viewer renders it as a big heading. You write **bold** and you get bold. You write - item and you get a bullet point.

AI assistants love Markdown for a few practical reasons. It's compact (uses far fewer tokens than HTML for the same structure). It's portable (every developer tool on Earth understands it). And it's the format their training data was full of, so the model knows the syntax cold. That's why your AI defaults to spitting out Markdown whenever its answer has headings, lists, or tables.

Why does my computer show it as raw text?

Because your computer, out of the box, doesn't have a Markdown viewer installed. Notepad on Windows and TextEdit on Mac are plain-text editors: they show whatever's in the file, byte for byte. They don't know what the hash marks and asterisks are supposed to mean.

This is a real friction. The chat window where ChatGPT answered you renders the Markdown beautifully. But the moment ChatGPT hands you a downloadable file, the friendly rendering stays on the website. The file itself is just the underlying syntax.

The 30-second answer

Drop the .md file onto the box below. It will render as a clean, readable document in your browser. No install, no signup. If you need to share it with a teammate, click the Share button at the top of the editor for a link they can open in one click.

That's it. The page you're reading right now is the tool. You can drag the file you got from ChatGPT directly onto this paragraph and it'll open above.

Other ways to open a .md file

If you'd rather not use a web tool, here are the desktop options, ranked by how much friction they add:

1. VS Code (free, developer-oriented): open the .md file, press Cmd+Shift+V (orCtrl+Shift+V on Windows) and you'll see a side panel with the rendered preview. Heavy install for one file, lightweight for someone who codes daily.
2. Obsidian (free, knowledge-base oriented): great if you want to keep a long-term vault of .md files. Heavier setup than the moment calls for if you just got handed one file from ChatGPT.
3. Typora (paid, $14.99): pure Markdown editor with a clean reading view. Great if you live in Markdown daily; expensive for opening one file.
4. Rename to .txt and open: yes, this "works", you'll see the raw text but lose all the formatting. Almost never the right answer.

How to share the file with a non-technical colleague

This is the trickier version of the problem. You opened the file. You can read it now. But your colleague (a marketer, a founder, your manager) can't, because their computer has the same Notepad-default-app problem yours had.

Three options:

• Share a link. Open the file on Vela Docs, click Share, send the URL. Your colleague clicks, the rendered document opens in their browser. No app, no signup needed on their end to read.
• Copy-paste the rendered content into Google Docs / Notion / email. Once it's rendered (in Vela, in VS Code preview, anywhere), select all, copy, paste into the destination, formatting survives.
• Export to PDF. In any Markdown viewer that supports print or export, choose PDF. Heavier attachment, but works in literally any email client.

The first option is what Vela Docs was built for. The collaboration goes further: your colleague can leave inline comments on specific sentences, and if you give them edit access they can fix typos directly, the same way Google Docs handles collaboration, but the underlying file stays as portable .md you can take anywhere.

What about .html files? Claude keeps giving me those too.

Same idea, different file type. AI assistants increasingly produce .html files for landing pages, slide decks, email templates, and one-pagers. The friction is similar: double-clicking the file usually opens it in your default browser, but you can't comment, can't edit inline, can't share it cleanly with a team.

The pattern is the same. Drop the file onto Vela Docs and you get a render plus a share-link plus inline comments. Walkthrough for HTML files.

One short takeaway

A .md file is just text with a few special characters. Your laptop doesn't know how to render it by default, but every browser can, drop the file onto Vela Docs and it renders in under a second. Share-by-link if a colleague needs to read it. That's the whole story.
