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.

Authenticates the real editorial process

Focus

We verify authorship from your natural typing rhythm: the pauses, corrections, and cadence only a real person produces.
