The Markdown editor
for people who don't write
Markdown.
You didn't ask for .md — your AI just gave you one.
MDX opens it like a document so you can tweak a sentence, fix a
heading, drop in a table, and save it back. No syntax to learn.
A field guide to writing without markup.
Markdown is great. Typing **asterisks** every time you want
bold is not. MDX lets you
format with a click — the file on disk
is still plain markdown.
Tables, code, math, diagrams — every one of them lives behind a button.
.md files from Built like a desktop app, not a web tab.
File tree. Tabs. Word count. Status bar. Native menus. The kind of editor you can leave open for a year.
A writing tool, not
a configuration project.
No code. Just write.
Bold, italic, headings, lists, math, tables, diagrams — every kind of formatting lives behind a button. Your file on disk stays plain markdown.
Bring your own key.
Ghost-writing suggestions powered by the model you choose. Plug in OpenAI, Anthropic, Google, xAI, or a local model — your key, your bill, your prompts.
Your cloud, your rules.
Files live in your iCloud, Drive, Dropbox or local folder. No MDX server in the middle, no account required, no telemetry.
Everything markdown can do.
None of the typing.
Looks like a document. Saves like a markdown file.
What you see is what gets committed. Open the same file in any other editor and it's still plain .md.

Your model.
Your key.
Your bill.
Tab-to-complete suggestions powered by the model you already pay for. We never proxy your prompts. We never see your text. The connection is between your editor and your provider — no middle-man server, no metering on top.
