Proof you penned it.
A publishing platform where the writing environment is the verification. No AI. No autocomplete. Just you, a blank canvas, and cryptographic proof you wrote every word.
The problem
Every post in your feed might be AI.
AI-generated content is indistinguishable from human writing. The volume is growing exponentially. Readers cannot tell what is real.
AI detectors guess based on statistical patterns. They flag human work as AI. They miss AI work entirely. They are unreliable in both directions.
We don't detect AI. We verify humans. There's a difference.
How it works
The constraint is the feature.
Write
Pennit gives you a blank canvas. No paste, no autocomplete, no AI assistance. Every character is typed by you, captured by the editor, keystroke by keystroke.
Publish
When you are done, hit publish. Your content is cryptographically signed with composition metadata and hosted behind a unique verification link.
Share
Share your pennit link anywhere. Readers see your article and its verification badge. The link is the proof.
The proof
Medium proves you published it.
Pennit proves you wrote it.
Verified human composition. The author typed every word in Pennit's constrained writing environment, with no paste, no autocomplete, and no AI assistance.
Your article, rendered on canvas — readable by humans, invisible to crawlers. The content cannot be scraped or ingested by AI training pipelines.
For writers
Pennit lets you prove yours isn't AI.
Freelancers & Journalists
Editors are running copy through AI detectors. Clients are suspicious. A pennit gives you a verifiable signal, not a disclaimer.
Essayists & Newsletter Writers
Tired of “this reads like ChatGPT” accusations? Your reputation is built on original thinking. Pennit proves it.
Students
Application essays, thesis work, academic papers. Institutions question everything. A pennit settles the question.

Original perspectives on LinkedIn, personal blogs, industry outlets. Differentiate your work from the AI flood.

Pennit doesn't help you write.
No autocomplete, no suggestions, no AI. Just you and a blank canvas. That's the point.
