Students submit AI essays. Professors can't prove it. Detection tools fail with false positives destroying trust.
Recruiters doubt writing samples. Publishers question article authenticity. Freelancers lose credibility.
Copyright disputes with no proof of authorship. IP claims fall apart without creation evidence.
Cryptographic proof of human creation captured at the moment of writing. Tamper-evident. Privacy-first. Blockchain-anchored.
Write in our secure editor. Your unique typing rhythm gets captured locally—like a fingerprint for your writing style.
Text + keystroke patterns create a SHA-256 hash. Impossible to fake, impossible to reverse-engineer.
Hash gets timestamped on Polygon L2 via EAS attestation. Public, verifiable, immutable proof forever.
Download PDF certificate with QR code. Share verification link. Prove authorship anywhere, anytime.
Privacy by design. Enterprise-grade security. Consumer-simple experience.
Your typing rhythm is as unique as your fingerprint. AI can't replicate the subtle timing patterns of human keystrokes.
Keystroke data never leaves your device. Only cryptographic hashes are stored, ensuring complete privacy protection.
Polygon L2 integration provides bulletproof timestamping with public verifiability at minimal cost.
Export to any format. Share anywhere. QR codes for instant verification. Works with every platform.
Professors sleep soundly knowing every assignment is authentically human-written
Editors trust their contributors with cryptographic proof of human authorship
Establish clear chain of authorship for copyright and IP disputes
Because it's your writing. Privacy is architecture, not a preference pane. In the age of AI, how your data is handled should be different.
Keystroke patterns never leave your device. Only cryptographic proofs are transmitted, ensuring your biometric data stays completely private.
Beyond standard end-to-end encryption, we encrypt your data at the layer immediately before any external processing.
Built-in monitoring detects unauthorized use of your authorship certificates across the entire web, not just within Puddin'.
We believe in a future where human creativity is verifiable, where authentic authorship is provable, and where your words carry cryptographic weight.
