Questions & Answers

As answered by people managing EPOS-AI and Nullstack.

What makes your product unique?

EPOS-AI's answer

EPOS-AI reads and remembers your entire manuscript across sessions. Unlike generic AI writing tools, it understands narrative structure, tracks character consistency across chapters, and gives editorial feedback with full story context — not just on the current paragraph.

Why should a person choose your product over its competitors?

EPOS-AI's answer

Most AI writing tools lose context after every session and treat a novel the same as a blog post. EPOS-AI is built exclusively for fiction authors — it reads your entire manuscript, remembers your characters and worldbuilding across sessions, and offers three levels of editorial analysis that check consistency across chapters. It doesn't generate text for you — it makes your writing better. Swiss-hosted, GDPR-compliant, your manuscript never leaves Switzerland.

How would you describe the primary audience of your product?

EPOS-AI's answer

Fiction authors writing novels and series, self-publishing indie authors, traditionally published writers, freelance editors looking for AI-assisted manuscript analysis, copywriters and content writers who need deep text editing beyond grammar, and journalists working on long-form narrative pieces.

What's the story behind your product?

EPOS-AI's answer

Built by Marcel Tobien, a published author with 12 books across urban fantasy, children's fiction, cozy romance, and non-fiction. After years of frustration with AI tools designed for marketers, he built the writing studio he wished existed — solo, from scratch, in Weggis, Switzerland.

Which are the primary technologies used for building your product?

EPOS-AI's answer

Node.js, PostgreSQL, Claude by Anthropic (primary AI), Gemini and GPT as fallbacks, Stripe for payments, LanguageTool for spell-checking, hosted on Ubuntu with Nginx and PM2.

Who are some of the biggest customers of your product?

EPOS-AI's answer

  • Independent fiction authors in the DACH region (Germany, Austria, Switzerland)
  • Self-publishing authors working on novel-length manuscripts
  • Writers seeking professional-grade AI editing for their fiction
