For the novelist who writes the same chapter four different ways. For the essayist who doesn't know the thesis until page three. Quillium keeps every version, so nothing is ever lost.
Coming April 2nd
What makes it different
Fork any sentence. Keep every version. Navigate your creative decisions like chapters, not mistakes.
No more "draft 1," "draft 2," "draft FINAL." Your ideas live in the document itself: visible, selectable, alive. Switch between them instantly. The one you didn't choose is still there when you need it.
AI that annotates, not interrupts. Ask for feedback, find the right word, get clarity — all without leaving your flow.
It isn't a chatbot in the corner. It responds to your text right where you are, giving suggestions as you write. Note that this feature is completely optional and currently requires that you provide your own API key.

Comments, revisions, and suggestions float beside the text they're about. Not buried in a sidebar. Not lost in a thread.
Every note is anchored to the exact phrase it concerns. Scroll past it, and it moves with the text. Resolve it, and it disappears cleanly.
The Manifesto
They don't. Neither do you. That's not a flaw.
Writing is a web of attempts — a tangle of better and worse, a conversation between drafts. Every blank page pretending otherwise is lying to you.
"What if we treats non-linearity as a feature, not a problem to manage?"
