Which AI detector should I trust?

I’m really confused about AI detectors. When I check the same content with different tools, some say it’s 100% human while others say it’s 100% AI.

So which one is actually reliable and how do you deal with these mixed results? I just want to understand how to judge this properly

I’ve tried the following ones but the results are completely different every time.

Pangram
Originality
GPTzero
Winston
Quillbot
Grammarly
ZeroGPT
Scribbr
AIDetector
Sapling
Humanizeai
NoteGPT
