Not Slop

Sign and verify human-written text. Stop the slop.

Not Slop lets you prove your writing is human — directly from Chrome. Type anywhere on the web and the extension silently captures your keystroke cadence in the background. When you're ready to sign, click the small Not Slop icon that appears in the corner of any text box. Your text is signed with a verification link anyone can check. No copy-paste. No separate app. Write where you already write — Gmail, LinkedIn, Docs, X, anywhere — and sign in place. Features: - One-click signing: a small icon appears in any text box once you've typed enough — click it to sign - Side panel composer for drafting and signing longer pieces - Keystroke cadence analysis proves you actually typed it - Tiered verification: basic signed text, or full human-typing-verified - Verification links anyone can check — no account needed to verify - Draft auto-save synced to your account - Import selected text from any page - Identity verification through the web app Keystroke data is captured locally in your browser and only sent when you choose to sign. The typing pattern is analyzed to determine if the writing is consistent with human authorship. This evidence is attached to the signed record and publicly verifiable. Stop the slop. Prove you're human.
