Proving human work in an AI world

We're building the infrastructure of trust that preserves space for authentic human expression in the age of AI.

AI Writing Detection Is Broken

AI can now write like a human. But we're solving the detection problem backwards.

Current AI detectors analyze finished text and guess - leading to false accusations against real human work while sophisticated AI slips through. Students get flagged for writing too well. Journalists face skepticism. Honest people pay the price.

We're flipping that script.

The Better Way: Proof Through Process

Sapien isn't anti-AI. We believe both human and AI content can coexist. But they should be distinguishable.

Sapien proves you're human by capturing your writing process and creating verifiable proof of your unique thinking.

Every human has a unique cognitive fingerprint - the way you pause, revise, and refine your thoughts. These behavioral patterns can't be faked by AI because they require genuine human thinking.

We capture proof during the writing process itself and create cryptographic evidence of authentic human thought in action.
