Frequently Asked Questions
Is Winston AI a good AI detector?
Yes — Winston AI is one of the best single-engine detectors available, which is why OmniDetect includes it as one of our 3 consensus engines. In our 211-sample benchmark, Winston achieves 92.2% TPR with only 3.5% FPR. However, a single engine can still make errors. OmniDetect's consensus approach cross-verifies Winston's results with GPTZero and ZeroGPT to reach 96.1% TPR and 2.5% FPR.
Is Winston AI better than OmniDetect?
Winston AI is excellent as a single engine, but OmniDetect includes Winston plus two more engines (GPTZero + ZeroGPT). The consensus verdict is more accurate than any single engine alone — 86% fewer false positives than the most aggressive engine. You get Winston's analysis plus two independent second opinions.
Is Winston AI free?
Winston AI offers 2,000 free words per month. After that, plans start at $12/month. OmniDetect offers free scans daily with no signup required — including real GPTZero detection with sentence-level analysis. Full 3-engine consensus (including Winston) starts at $9.99/week.
Can Winston AI detect ChatGPT?
Yes, Winston AI can detect ChatGPT-generated text with a 92.2% true positive rate in our benchmark. However, it has a 3.5% false positive rate — meaning roughly 1 in 30 human texts gets wrongly flagged. OmniDetect cross-verifies Winston's result with GPTZero and ZeroGPT, reducing false positives to 2.5%.
