What is live, what is under review, and what we are building right now. ByHuman has two connected products: verified writing (prove how your text was written) and Feed Shield (read a cleaner timeline).
Verified writing receiptslive
The Chrome extension observes how a post is composed in the X composer — typed, pasted, edited — and signs a receipt with a verdict (Mostly typed, Mixed, Mostly pasted). Receipts get public pages anyone can check.
Receipt stampslive
A short code inserted into the post itself binds the published text to its receipt, so the proof travels with the writing.
Gmail receiptslive
The same observed-writing receipts for email: stamps bind on send, drafts keep their session across reopens. Rolling into the store build after X.
Receipt verificationlive
Anyone can verify a receipt's signature and text hash on the site — no account needed. The signing public key is published at a well-known URL.
Effort points & leaderboardlive
Verified writing earns points; the leaderboard ranks writers by valid public receipts, not by engagement metrics.
On-chain anchoringin review
Receipt digests anchored on an Arbitrum registry contract for tamper-evident verification that does not depend on trusting our servers.
Chrome Web Store listingin review
The extension is submitted to the Chrome Web Store; unpacked installs work today from the open-source repository.
Feed Shieldin development
A reader-side filter for the X timeline: crypto spam, promo, engagement bait, slop threads and more get dimmed, collapsed, or hidden — with an explanation and a one-click override on every decision. Strictness is a single slider.
Deep Filterin development
An opt-in AI second opinion for Feed Shield: ambiguous posts are scored server-side across six observable-content categories. It classifies writing patterns, not authorship — it is not an AI detector.
