Overview
GPTZero is an AI-text detection product used in education and publishing workflows. Scores are probabilistic signals — not courtroom proof that a human did or did not write something.
Use detectors as a conversation starter with process evidence (draft history, citations, oral checks). Do not make high-stakes decisions from a single percentage.

How should I evaluate GPT-Zero before I buy in?
Use this checklist on GPT-Zero (and one alternative) before you change a team workflow.
- Run one real task you already understand — not a vendor demo — and score accuracy vs edit time.
- Check privacy: what data is stored, for how long, and whether training on your inputs is opt-out.
- Confirm commercial license / ToS for your use case (client work, education, or internal only).
Evaluate detectors with known samples
Build a tiny set: human essays, AI drafts, and AI+human edits. Measure false positives/negatives before you set policy thresholds.
Pair with literacy lessons on synthetic media and classroom AI use so tools do not outrun pedagogy.
FAQ
Is GPTZero free?
- Catalog pricing is freemium. Confirm current word limits and education plans on GPTZero’s site before classroom rollout.
Can GPTZero prove AI wrote this?
- No detector can prove authorship with certainty. Treat scores as weak evidence and combine with drafting process, sources, and human judgment.
