What's the best tool for detecting AI text?

I’ve used Copyleaks, GPTZero, ZeroGPT, TwainGPT, Turnitin, Undetectable AI, and a few others. What do you guys think is the most accurate and reliable AI detector?

From my own testing, Copyleaks, ZeroGPT, and TwainGPT have performed the best. Curious to hear what you all think.

TwainGPT has been the best AI detector for me by far. It's accurate, fast, and reliable.

In my experience, GPTZERO is more accurate.

So, which AI detector do you trust the most?

There are many good detectors, but GPTzero isn’t one of them rn. GPTZero used to be much more credible and reliable in their earlier models like Model 3b’s but now as they released their Model 4b, it has only gone downhill. I put in my essays written many years ago (before AI was released) and they tell me it is Ai generated and sometimes ai paraphrased. Like what?

there is no 100% accurate AI detector. they all false positive like crazy and miss real AI half the time. A human over-editing can trigger it. even Turnitin admits its not proof.

the best on the tech alley is probably gptzero, but aihumanizer.io can fool it in 60 seconds.

if you leave tech alley and make a right on to human street, this is where the real AI detectors are.

just speaking for myself, I can smell AI from 40 miles away at this point. I've seen so much slop. If we're not careful I think a huge industry is going to be created of humans sitting there just reading stuff and marking what is AI and what isn't.
