On illuminarty.ai i find this tool that detect AI generated images, synthetic, tampered images and Deepfake. There's a Free version and some subscription plan. After a couple of test it actually showed somewhat accurated results:

.> 70% Chance on actual AI drawing tested

<20% On (human) edited images

<5% On original handmade drawings

EDIT - Not so great with realistic AI Photo. Somehow works better with AI art.

UPDATE - I find this one who works better on photo | Is It AI
