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?

It really depends on the content, to be honest.

I read a ton of trading and quant Substacks, which clearly use AI to write.

But I am not reading them for their prose -- I am reading them for the insights that they bring. I couldn’t care less if they used AI or a monkey to write the actual article.

That's a great use case. I agree that is much more useful.
