Humanums is the most complete go-to-market in this category — a real pricing ladder, a client logo strip, cited sources. The mechanism underneath is where Proofwriter differs.
| Proofwriter | Humanums | |
|---|---|---|
| Core idea | "AI detectors guess. Proofwriter records how you actually wrote it." | "AI detectors guess. Humanums collects proof while you write." |
| Anchoring the proof | Bitcoin blockchain — independently verifiable, not tied to any one company | A self-signed hash |
| Where you write | A full distraction-free editor with themes, goals, and checkpoints | Badge-embed model, desktop-publishing oriented |
| Pricing | Free tier, then $8/mo or $72/yr | Full pricing ladder with a 14-day refund policy |
| Third-party validation | Not yet — a real gap, and something we're actively working on | Cites Stanford HAI and Turnitin, runs a named-client logo strip |
Comparison based on Humanums' own public positioning and homepage copy at the time of writing.
Humanums backs its proof with a self-signed hash — verifiable in the sense that the company vouches for it, but it depends on Humanums as a company continuing to exist and stand behind it.
Proofwriter anchors every Proof to the Bitcoin blockchain instead. The timestamp is independently checkable by anyone, and it doesn't depend on any one company staying in business — the durability comes from the chain, not from us.
Where Humanums is ahead: real third-party validation — cited research, a client logo strip, an established pricing ladder. That's a genuine gap for Proofwriter today, and one we're working to close rather than pretend doesn't exist.
