Show HN: Quillium, the non-linear writing app

Public beta lauunch!

I built a SvelteKit + Tauri writing app that treats revision as a first-class concept. You can fork any sentence or passage into branches, switch between versions inline, and keep everything in one document instead of maintaining separate draft files.

It's different from Git in the sense that you can try different combinations of these branches AND that these branches go infinitely nested

The editor component was made with CodeMirror, and I tried really hard with implementing robust data persistence by storing with SQLite.

There's also optional AI feedback if you bring your own API key, but it's not the point of the app (enable it in settings).

Still in beta and rough around the edges. Would love feedback!
