Using Claude Code for things other than code?

If you write with your agent, you shouldn't have to do it in a coding app. Flywrite brings the same workflow to an app made for writing.

A beautiful markdown writing experience

Write in a clean rendered view, where your markdown reads like the finished piece. Or flip to classic source mode when you want to see the raw markdown. One keystroke switches between them.

A real terminal, not a chat box

Run the actual Claude Code, Codex, or any CLI agent, with your subscription, your skills, and your memory. It sees what you've selected and edits your files directly, while you keep hand‑editing right alongside it.

Every change, checkpointed

Flywrite checkpoints your work before an agent touches anything. See exactly what changed, restore any earlier version. Hand the keys to an agent without holding your breath.

Make it yours

Light mode or dark mode. Full control over fonts, color themes, and the app layout. Tune the whole studio to the way you like to write.

Backup to GitHub. Simplify Git.

You never have to write a git command. It's automatic or a push of a button.

Fly through it from the keyboard

Every function in Flywrite has a keyboard shortcut, and every shortcut is customizable. A command palette puts it all one keystroke away.

Hi, I'm Brian.

I make my living writing: newsletters, YouTube scripts, courses. And these days, Claude Code is my collaborator on nearly all of it.

But I never liked creating in a code editor. Cursor and VS Code are built for shipping software. Prose deserves better than a preview pane in a dev tool.

So I built the writing experience I actually wanted: calm and paper‑like where I write, a real terminal right below it where my agent works, and everything quietly checkpointed and synced to GitHub the way I'm used to.

I made Flywrite for myself first, and now I'm building it in public. I'd love for you to be one of the first to try it.
