Is GPTZero Worth the Price?

GPTZero is the best AI detector available right now, but that's a low bar. It's more accurate than competitors and the sentence-level highlighting is genuinely useful. But false positives remain a serious issue, especially for non-native English writers. Use it as one signal among many, not as definitive proof. The fundamental problem is that AI detection is an arms race, and detectors are losing.
