An AI document editor for people who care about words.
Erga gives you the expressive power of a coding agent without forcing you to give up control over your text.
Write it with your agents: ask an agent for a change in plain words, and watch it land in the text, where you can still edit it by hand. A document is a real web page, so it can be a design doc with a working prototype, a slide deck or an interactive explainer. Everyone in it sees each edit as it happens.
Try it at erga.dev.
Erga runs on your own Cloudflare account and domain. You need Bun, git, a GitHub account and a Cloudflare account on the Workers Paid plan.

Or give your coding agent this prompt in an empty folder: "Set up my own Erga
from https://github.com/koomen/erga at . Clone it, run
bun install, then follow bun erga setup skill." Every deploy runs on your
machine, from your clone: git pull, then bun erga deploy <commit> <host>.
bun erga skill tells how to work in this repository: a feature branch for
each change, the tests, and how a change reaches staging and production.
