Watermarks say AI was involved. We show to what extent.
Providers will mark every model output — even when you only have a single word corrected. Anyone who writes themselves and uses AI selectively ends up under the same mark as a fully generated text. Hermes records how your book comes about instead, and turns that into a checkable record.
- Per passage, not per book
- Writing time and revisions evidenced
- Signed, checkable without an account
Hermes3000 is truly powerful when it comes to co-writing books with AI. What convinced me most were the smart assistance features and the accompanying book chat – because the AI essentially acts as a 'counterpart' here.
Patrick Meier
bestselling author and content creator
Literature has always been a place for speculation. Perhaps we're standing on the threshold of something entirely new. A transformation. Away from the human as we know them – toward something we can't even imagine yet. Humans were never finished. 100,000 years ago, they were different. Three million years ago, they didn't exist. Why should it suddenly end now?
Hermes 3000 enables you to create high-quality interactive educational materials — with the maximum that AI can currently offer. No other system leverages the technology as consistently.
