Marcel Tobien
Author and founder of EPOS-AI
A tool built by an author, for authors
I am Marcel, and like you, I write books. Novels, children’s books, non-fiction. I know the struggle with a manuscript, the point where you get stuck, and the joy when a character suddenly comes alive. That is exactly why I built EPOS-AI.
EPOS-AI is not a faceless corporation. There is a real person behind it, refining this tool every day so you can write more freely. And you are not just a customer. You are part of something we are building together.
Why your voice matters so much: The more authors who find us, the stronger EPOS-AI stands. That gives me the room to keep making the tool better and to keep prices fair over the long run. So your review comes back to you and to everyone who writes with us.
Warmly, Marcel
Lucerne, Switzerland

My novel is close to publication. I had the editing done with EPOS and was able to put its advice to real use. It genuinely moved my writing forward.

I am so taken with EPOS. I love the sparring partner: it hands me ideas I would never have reached on my own. A success through and through.

My texts became livelier and more rounded. Epos managed to make everything more coherent. They are still my words, but they read better.

I only started with Epos today, so I cannot say too much yet. The first style analysis is genuinely impressive. One small thing: as a Swiss writer I would love the correction not to flag the German double-s as an error.

EPOS-AI did not just improve my manuscripts and make them more alive. It made me a better author too. Full stop.
