Your Substack newsletter,
provably human
Readers subscribed for your voice, your perspective, your ideas. Scripli gives you a certificate to prove every edition is genuinely written by you — directly inside the Substack editor.
Substack has seen an explosion of AI-generated newsletters. Readers are increasingly aware — and increasingly skeptical. A Human Authenticity Certificate displayed consistently in your publication tells subscribers, before they even open the post, that what they're about to read came from a real person sitting down to think and write.
How it works with Substack
Install the Scripli Chrome extension
Add Scripli from the Chrome Web Store. It works across all the web-based writing tools you already use.
Open a new Substack post
Navigate to your Substack dashboard and open the post editor. Scripli recognises the Substack writing environment automatically.
Start your session
Click the Scripli extension icon to start recording your session. Your writing session begins — your words never leave your browser.
Write your newsletter
Write as you normally do. Think, draft, revise. Scripli records the behavioural proof of your writing process, not your content.
Receive your certificate and share it
End the session when you're done. Your Human Authenticity Certificate is issued immediately. Add the certificate number to your author bio, the post footer, or your "about" page.
What makes this seamless
- Works directly inside the Substack web editor — no exports or copy-paste
- Your post content stays in Substack; Scripli never reads or stores it
- One certificate per writing session — covers drafting in a single sitting
- Certificate number is shareable and publicly verifiable
- Builds reader trust with a consistent, independent signal of human authorship
