EPOS-AI was built by a novelist, for novelists. Swiss-hosted, privacy-first, and built around one obsession: your manuscript.
EPOS-AI is a specialized AI writing assistant for fiction authors. Unlike generic AI tools built for marketing copy or business emails, every feature in EPOS-AI was designed for the specific challenges of long-form creative writing.
The core problem we solve: Most AI tools forget everything after a few pages. EPOS-AI holds your entire manuscript in context — up to 120,000 words — so it can give you feedback that actually knows your story.
Build tension arcs that keep readers turning pages. From three-act structure to the hero's journey — EPOS-AI understands narrative shape.
Protagonists with real depth and coherent motivations. EPOS-AI remembers every character, every detail, across your entire manuscript.
Create consistent, immersive worlds without losing track of the details. Up to 120,000 words of context, always available.
Not a yes-machine — a sparring partner that spots clichés and challenges weak choices. Like a literary editor who has read your whole book.
There are many AI tools, but most are optimised for short-form marketing content. EPOS-AI is a tool built by a creative, for creatives. Our approach is grounded in the principles of classical and contemporary storytelling.
Your writing style is your most valuable asset — EPOS-AI adapts to you, not the other way around. As a Swiss project, we stand for reliability, privacy, and the highest technical standards. Your data is stored in Switzerland and never used to train AI models.
Founder, Novelist & AI Developer · Weggis, Switzerland
As a novelist, I experienced firsthand how frustrating it is when an AI forgets your protagonist after 30 pages. I built EPOS-AI not as a tech product, but as the tool I needed when writing my own six-volume fantasy series. Over ten years of experience as an author flow into every feature.
We believe every person carries a story worth telling. Often these stories fail not from lack of talent, but from the friction of the writing process itself.
EPOS-AI is here to remove that friction. We give you the tools to shape a fleeting idea into a finished literary work — your own personal epic.
