Quillium Is Not an AI App
How AI hype swallowed the 'writing tool' category, and why Quillium's actual innovation keeps getting buried under it.
I keep having the same conversation.
“How is this different from Grammarly?” That’s what a friend replied when I posted about Quillium on my Instagram story. He didn’t even look at the website—he saw “writing tool” and assumed the worst. Someone else glanced at the name, skimmed the tagline, and asked: “So how is this different from ChatGPT?”
It’s not different from ChatGPT. It’s not even related to ChatGPT! Quillium is a writing app. You open it, you type words, you edit those words. That’s it. The thing that makes it interesting is that you can branch those words: fork a sentence, try it three different ways, keep every version alive. It’s just a better way to write.
But I understand why people don’t hear that, and it’s honestly worth talking about why.
Every new tool is guilty until proven innocent
We’re living in the aftermath of an AI gold rush. Every product launch in 2025 and 2026 has “AI-powered” slapped on it somewhere, whether the product actually uses AI or not. Notion added AI, Google Docs added AI, Grammarly has been AI for years, and even note-taking apps and to-do lists have AI features now.
So when someone sees a new writing-adjacent product, the pattern match is instant: new + writing = AI thing. It doesn’t matter what your landing page says. It doesn’t matter that your hero section talks about branching and revision. The category “writing tool” has been so thoroughly colonized by AI marketing that people’s brains skip straight to the assumption.
This isn’t anyone’s fault; it’s what happens when an entire industry spends two years screaming the same word.
The name doesn’t help
“Quillium” sounds like it could be an AI product. It’s got that same cadence as Grammarly, Jasper, Writesonic—vaguely literary, vaguely techy. If you’re pattern-matching (and everyone is), the name alone might be enough to trigger the assumption.
I picked the name because I liked it (and I still do), but I recognize that it’s swimming against a current. The name says “writing” and in 2026, “writing” apparently means “AI.”
What Quillium actually is
Quillium is a non-linear prose editor. Here’s what that means in practice:
You’re writing an essay, and you get to the second paragraph where you’re not sure if the tone should be formal or conversational. In Google Docs, you’d either commit to one or copy-paste the paragraph somewhere else and try both. In Quillium, you branch the paragraph. Both versions live in the document, side by side, and you can switch between them, compare them, or keep writing from either one.
It’s version control for prose—the same concept programmers have used for decades (Git, branches, forks), applied to the kind of writing where revision is the work.
No text is generated for you, no sentences are autocompleted, and no grammar is “corrected” without your input. You write every word yourself.
Then why did people mention AI?
Because we do have an optional AI feature—emphasis on optional. It’s off by default, it’s a feedback tool rather than a generation tool, and it requires you to bring your own API key. By every measure, it’s a footnote. I wrote about the philosophy behind it in AI Is Not the Point.
But even a footnote about AI can become the headline. A friend shared Quillium with her creative writing club. She described it exactly right: non-linear writing, branching sentences, keeping multiple versions alive. The club liked the editing concept. But the AI part—mentioned at the very end as a “completely optional feature”—they were not too fond of. AI stealing art, the environmental costs, AI controversy in general—they didn’t want it anywhere near their writing.
That’s the problem: the interesting work gets lost in the noise, and a feature that barely exists becomes the only thing people see. The landing page now has zero mention of AI for exactly that reason.
The real problem is category collapse
Here’s what frustrates me: Quillium’s actual innovation—non-linear editing, branching, keeping every draft alive—is genuinely new. No other writing app does this, not Scrivener, not Ulysses, not Notion, not Google Docs. The concept of treating revision as exploration rather than destruction is something writers have needed for a long time.
But that message can’t land if people never get past “oh, another AI writing thing.” The real feature gets buried under an assumption about a feature that barely even exists. This is what happens when a hype cycle swallows a category. Anything adjacent gets misread, and the interesting work gets lost in the noise.
What I’m doing about it
Because of these incidents, I’ve changed the landing page so that it now leads with “writing app” in the meta descriptions instead of anything that could be read as ambiguous. There’s a line in the hero section that says it plainly: No AI ghostwriting. No autocomplete. Just a better place to write. (although that’s probably been changed by now, after many iterations of the landing page)
It feels a little silly to have to disclaim what your product isn’t, but if that’s what it takes for people to actually see what it is, fine. I’d rather over-clarify than be permanently miscategorized.
If you’ve read this far and you’re a writer who revises obsessively, who keeps five versions of the same paragraph, who treats every word choice as a decision—Quillium is for you. No AI required.
