How We Verify Authorship
ValidDraft looks at three parts of how you write that no AI can fake.
Struggle
Writers edit their work. We capture the real process of writing, erasing, and improving to show the human effort behind each sentence.
Focus
We verify authorship from your natural typing rhythm: the pauses, corrections, and cadence only a real person produces.
Entropy
Human writing isn't linear. The way you move your mouse and make edits creates a distinctly human pattern.
Professional-Grade Verification
State-of-the-art capabilities built for the people who write for a living: authors, journalists, and freelancers.
