Null AI - Detect AI Media

I tested this app using multiple photos that I personally took and know with certainty are 100% real. In every case, the app rated them as highly likely to be AI-generated. This raises serious and dangerous credibility concerns. If an app markets itself as a tool for determining whether images are AI-generated, accuracy is not optional. In my experience, this app consistently produced false positives on authentic photographs. That is not a minor flaw. A tool that falsely labels real images as AI-generated can distort reality, damage credibility, and contribute to misinformation in the opposite direction. When detection tools are wrong but presented as authoritative, they create the very confusion they claim to solve. There is no clear disclosure of accuracy rates, error margins, or methodological limitations. Without transparency and demonstrable reliability, this app should not present itself as a credible AI-detection resource. Based on my testing, I absolutely do not trust Null AI. I highly recommend finding a more reliable tool.

It seems like the app defaults to labeling likely AI. The only times it gave a correct response with not AI, were when I included the images original exif data. I gave it some very realistic appearing ai images, and was impressed that it called out even the most realistic. But it also called out images had personally taken as ai (sometimes citing similar reasons - like repeating patterns in grass or fingers being off) with no such edits being performed by me. Assuming the image has been stripped of exif data, I assume this app labels 90% of real as ai and 100% of ai as ai. I’d have to do further testing. Regarding og review: The dev reached out a few days after my review (unsure if related or excuse was legit). I should have updated my review then though, giving benefit of the doubt. I’m not sure exactly what my comments were. I had a premium account (trial) when I left the review, am not a competitor, and it was completely honest.

I scanned unedited photos and videos that I took personally, of people and nature, in all of them the App found AI with 75% confidence.
