AI work creates Markdown.

Claude, Codex, Gemini - whatever you work with, it hands you .md files. Instructions, specs, context docs, contract drafts. And the tools you're told to open them in are built for programmers: raw symbols, monospace text, files managed in Finder.

“Hey, what do you edit .md files in?” That question is why Doca exists.

No syntax needed. Syntax still works.

Write like in a normal document. Format with the toolbar or type / for headings, lists, and tables. And if you know Markdown, keep typing it - # still makes a heading.

Your whole workspace. No Finder.

Open a folder and every file appears in the sidebar. Create files and folders, drag to reorganize - all in the app, without dropping back to Finder.

  • Every file in sight HTML, images, whatever your folders hold - visible next to your .md files.
  • One click to reference Duplicate, copy path, show in Finder - right where your files live.
  • Structure is performance When AI reads your workspace, organized context means better output.

AI that sees your file. And the exact lines you mean.

Connect the AI you already pay for: Claude Code, Codex, or Gemini CLI. Doca knows the open file, so there is nothing to paste.

  • Mark for AI Select a fragment and mark it. It attaches to your message, highlighted in the doc.
  • Drag a file into the chat Reference any file by path the same way you mark text.
  • No API key, no new bill Your existing subscription. And the editor works fully without AI.

Cursor or VS Code

Those are built to write software. Doca is built to read and edit documents. Same files, none of the noise.

If you live in backlinks and plugins, stay. If you just need your files, this is the calm version.

Pasting into chats

Stop retyping context into ChatGPT or Claude. Your files stay on disk, and AI works on them directly.

I stopped copying text between Claude and my editor. Doca just knows the file I'm in.

I got a contract draft as a .md file, opened it in Doca, and sent my notes back the same day.

I don't know Markdown. Turns out I don't need to.

Questions, answered.

Doca is a Markdown editor for Mac. It opens .md files as clean documents, formats with a toolbar instead of syntax, manages files and folders in-app, and can connect to your own AI - Claude Code, Codex, or Gemini CLI. One-time purchase, macOS only.

No. Format with the toolbar or type / for headings, lists, and tables. If you do know Markdown, the syntax shortcuts still work - # makes a heading, like anywhere else.

Doca connects to Claude Code, Codex, or Gemini CLI using the subscription you already have. No API key, no extra bill. The editor works fully without AI - the assistant is optional.

Because your AI tools read and write plain .md files. Converting to Word breaks that loop. Doca keeps files as plain Markdown on disk, so everything your AI produces or consumes stays exactly where it works.
