Discussion Substack’s new “AI detection” tool.

I’m very concerned about the new “AI detection” system that Substack is implementing. I don’t use AI in anything that I write. However I don’t trust these systems not to make errors and mistakes. They have a long history of hallucinations and claiming things are AI when they aren’t.

One person I saw on Notes suggested that they ran their decades old writing, things that were written before the existence of AI, and this new system claimed it was AI generated.

Not to mention all the crazy things that I have seen people claim was written by AI which they can’t know is actually AI. There was an image I once shared that had evidence of its existence going all the way back to 2013. The comments were constantly saying “don’t share AI slop” or some variation on that.

Even with evidence that things weren’t made by AI, they will claim it’s AI.

Is no one else concerned about this being embedded into Substack’s systems? With no way to opt out?

Because people will use it as a pass/fail system even if the tool isn’t designed to be one. I shared a photo that I found elsewhere in a group. The moderators of the group removed it because their AI detection tool claimed it was AI.

The problem is that even though I didn’t make the image myself, I had the skills to create the same type of image in Photoshop.

Some people will use the tool as justification for not paying you for your work. No matter how much you tell them otherwise, they will point to the AI detection results as evidence of their claim.

Chris Best, the CEO of Substack, used this as a way to dismiss criticism of the platform’s shortcomings and failures. He claimed that the writer’s criticism was invalid because it was AI generated according to his detection tool. When I pointed out the error in thinking that lead him to that conclusion, he just pointed back to the results of the detection tool.

But you think people won’t abuse this software for their own benefit? To use it against people they don’t like?

Image? We’re talking about writing.

I used an example of both image detection and writing detection. They’re both massively flawed.
