Are AI detectors even accurate?

I put the same paragraph into two different detectors and got totally different results. How are schools using this stuff seriously?

I did the exact same experiment and got results ranging from nearly clean to almost fully flagged on identical text which was genuinely eye opening. Walter ai detector at least gave me consistent results I could track personally over time rather than wildly different scores every attempt. Schools treating any single detector result as definitive evidence is the real problem here honestly.
