Why
The Standard
Final prose can look human while trust erodes. JITTER restores what was lost: a defensible receipt of real drafting—so verifiers can rely on evidence of labor, not suspicion.

Frequently Asked Questions
Is JITTER an AI detector?
No. Probabilistic detectors analyze finished text and estimate likelihood. JITTER records how the draft was built and issues a cryptographic receipt. Detectors guess. We certify.
What does JITTER prove?
JITTER gives you a process receipt: evidence the author composed the work in Google Docs over a real session—typing, pauses, and revisions—rather than pasting finished text wholesale. It does not prove originality of ideas, factual correctness, or that no words were transcribed from elsewhere. It answers whether the draft was built in-session with human labor.
Does JITTER work alongside Turnitin or GPTZero?
Yes, and it fills the gap they leave. Probabilistic detectors analyze finished text for statistical patterns. JITTER issues a cryptographic receipt of your drafting process — affirmative proof you can share with any teacher, editor, or administrator, especially when a detector produces a false AI flag on honest writing.
Is JITTER FERPA and GDPR compliant?
JITTER does not collect personally identifiable information, document body text, or keystroke content. What leaves your device is limited to one-way hashes, the document identifier, and a numeric humanity score—retained for no more than 30 days. See the privacy policy for the full disclosure.
Is it free?
Yes. Completely. No ads, no subscriptions. JITTER is public infrastructure for human dignity. See our privacy policy for what we keep and why.
