Detector.io

AI content checker that scans your text across five AI detectors at once — GPTZero, Winston AI, ZeroGPT, AI Detector Pro and its own model — showing each provider's real score side by side, then lets you humanize flagged lines and re-check.

Detector.io is an AI content checker that runs your text through multiple popular AI detectors in a single submission. Instead of relying on one score, it combines GPTZero, Winston AI, ZeroGPT, AI Detector Pro and its own in-house model, then displays each provider's actual result in one dashboard so the scores are directly comparable.

Because different detectors use different models and datasets, they often disagree on the same text. Detector.io shows the real outputs from each tool — not averaged or invented scores — so you get a fuller picture of where your content stands before an audience sees it.

The platform also includes a humanizer that rewrites passages flagged as AI to sound more natural. You can choose which passages to work on, protect citations, headings, formatting and names so they stay unchanged, and then re-scan the revised text across the same detectors without leaving the tool.
