Retype builds directly off Markdown files, which you can store anywhere, including GitHub. The retype.com website is built directly from a GitHub repo, see https://github.com/retypeapp/retype

The retype.com website is also hosted on GitHub Pages. Any change that is committed to the GitHub repo will trigger the website to be rebuilt by Retype using GitHub Actions, see https://retype.com/hosting/github-pages/.

Hope this helps clarify that Retype is even more tightly integrated with GitHub, or any other source management system. You have complete control and ownership of your source content files.

You're still just describing a static site generator. Gitbook has Git integrated into its UI and rebuilds the site through the GUI on the fly.

GitBook is a static site generator, essentially. Just wrapped in an online UI.
