ProvenPost
A WordPress, Substack, and Ghost plugin plus standalone web app that mints a cryptographic 'hand-written' badge for each post — proving keystroke timing, edits, and total typing time — so independent writers can credibly claim authenticity.
independent writers, essayists, and Substack bloggers competing with AI-generated content
- Keystroke telemetry plugin that captures per-character timing, edits, and pauses and mints an encrypted receipt on publish
- Public 'human-verified' badge embeddable on any blog, showing time-to-write and edit count without exposing content
- Reader-facing analytics so writers see who views their proof badge and from where
- Cross-platform receipt export compatible with Medium, Substack, Ghost, and custom sites
AI-written content saturation is destroying trust in indie writing; Mitchell Hashimoto's public disclaimer is becoming standard — ProvenPost turns a manual disclaimer into a verifiable publishing asset.
Substack is actively partnering with Pangram for AI detection (Axios 2026), Hacker News thread exists, and multiple competing tools already have Chrome Web Store/WordPress listings — indicates real but reactive demand rather than proactive pull.Substack bets readers want to pay for content written by humans - Axios ↗WritersProof — Prove You Wrote It ↗
Space is saturated with near-identical products already shipped: RealStamp Verify (WordPress.org plugin), Humanums (WordPress badges), TypedTrust (keystroke/timing/edits proof), WritersProof (Chrome extension + Ed25519 signatures), proof-of-life (GitHub), and the open speakwrite protocol — at least 5 direct competitors with the same exact premise.RealStamp Verify - WordPress plugin | WordPress.org ↗TypedTrust - Prove Your Content is Human-Written ↗WritersProof - Prove You Wrote It ↗WordPress Plugin — Display Human Content Badges | Humanums ↗
Indie writers on Substack are notoriously price-sensitive (most charge $5–50/mo themselves) and free/open alternatives already exist (WritersProof, proof-of-life on GitHub, speakwrite open protocol) — willingness-to-pay for a badge is weak when Substack itself is rolling platform-level detection with Pangram.Which Substack Publications Charge the Highest Subscription Fees ↗GitHub - stefanrosscohen/speakwrite ↗
The AI-trust problem is structural and won't fade, but the category is likely to be absorbed by platforms themselves (Substack/Pangram integration, browser-level attestation) — standalone plugin value diminishes as detection moves upstream.Substack bets readers want to pay for content written by humans - Axios ↗
Keystroke capture and Ed25519 signing is technically trivial and proven by competitors already shipping it; however, Substack has no plugin system and Ghost's API is limited — the cross-platform 'plugin + web app' promise is much harder than it looks, especially the Substack/Ghost legs.WritersProof - Chrome Web Store ↗How to add a written by a human badge to your WordPress site - Humanums ↗
