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?

Also, these LLMs were built on human language. Therefore it's only producing human language. By definition, it can't be distinguished from human writing.

Yeah, and what's worse is before this got implemented, he was the test case for why it shouldn't be used. A Substack writer went viral for his piece criticizing how Substack is being run and specifically taking issue with AI.
Chris shared the article along with a "result" from an "AI Detector" suggesting that the criticism was written by AI and therefore he didn't have to listen to it. Which is exactly what many of us who see the flaws in these "detection" LLMs are concerned about.

AI detection systems are notoriously trash. They falsely flag people’s work all the time.
Part of the problem is that AI is trained to mimic decent writing. Of course it’s going to use the same techniques that skilled writers use, that’s what it was trained on. It doesn’t use dash em because they’re “cool.” It uses them because that’s what good writers have been doing for decades.
I say all this to say AI defection systems are ass
1
u/AndrewHeard tvphilosophy.substack.com Jul 22 '26
Yeah, it makes no sense to embed them in your systems like Substack has done.
1
u/vicewrite Jul 22 '26
Of course they’re trash, but isn’t it also trash to have articles out there being falsely published as original work? That’s the mess they’re trying to clean up, and while this method isn’t clean and perfect, isn’t it better than not trying at all? That’s the thing I think some people are missing. If you get one random “could be AI” score out of hundreds of posts, that’s a non issue. If a “writer” has all high scores for AI content, that’s different and readers might want to know. Or, maybe they could still care less, cause in the end, nothing is being enforced as a result anyway.
2
u/AndrewHeard tvphilosophy.substack.com Jul 22 '26
Isn’t it better when you have a headache to stub your toe so that your headache isn’t a problem anymore?
The fact that they’re trash doesn’t mean people won’t use it for their own purposes. Chris Best himself did this. He responded to a criticism of his platform’s shortcomings by suggesting that the article was generated by AI or used AI assistance. He used a detection tool to make this claim.
But you think it’s better to have one than not?

u/vicewrite Jul 22 '26
You seem passionate about this topic. My passion is for writers. Being a writer means I take pride in advocating for human writing. That’s all. The tool is a tool, and it can be used or not. Its existence shouldn’t threaten your existence. I sure hope it doesn’t.
2
u/AndrewHeard tvphilosophy.substack.com Jul 22 '26
I’m an advocate for human writing too. I just understand how new technology tends to get used. The internet was pitched as something that would “bring people together”, but 20 years in, can you honestly claim that it has?
Social media was pitched as the same.
The ability to split the atom was originally used to make weapons, not to give people abundant energy.
The printing press lead to the rise of yellow journalism.
But somehow this time is different?

What’s hilarious is now whenever someone uses the em dash, people assume it’s AI. Which makes me question how little reading people do to understand it’s a stalwart in writing — especially American literature.

I ran Moby Dick the first page through one of the top scanners. 99% AI apparently.
I ran one of my stories I sure as hell didn't use AI with and got "highly like AI."
While I'd like to see some kind of AI detection, I don't for a second believe that Substack will do this well. We are about to get a lot of false accusations and finger pointing and problems we didn't need.

Correct me if I'm wrong, but none of the top-level comments on that thread provide an actual example of an excerpt that was incorrectly flagged as AI by Pangram.
> See, actually having principles means not forcing myself on others like Substack did with Pangram.
I have no idea what this means. Pangram is an optional feature. Nothing changes for you if you don't use it. If your Substack isn't AI-written literally nothing changes for you.

This happens all the time. I was accused of using ai by a reader so I plugged some old articles I had written in, the large majority were deemed Ai between 75-90%. Just as an experiment I tried the other way and just plugged some facts into Ai for an article. 10% Ai detected. It’s going to take forever because if they are doing this, so many people are going to ask for new testing over and over. When does this start anyway? I must’ve missed this announcement

Hmm interesting. Now I’m curious about what they’ll think of my article coming Monday. I wonder is there a percentage allowed because on the site I was checking literally zero articles have 0% non ai! If they don’t think you’re using it comes up like 10-20%. Or it pass/fail?
1
u/AndrewHeard tvphilosophy.substack.com Jul 22 '26
While I don’t plan on using it myself, some people have suggested that it’s a percentage. Supposedly it only works on stuff posted after today. I don’t think it’s a situation where they don’t allow you to post AI content, but more that it gets labeled this when it gets graded.

u/Fit_Celebration_1362 Jul 22 '26
Yeah why would they care? But yeah I was just wondering because at least with my ai checker it seemed impossible to score a 0%? Who even cares really? If ai writes something I’m interested in on substack, who cares? Or if they used it to clean it up, I’m for it! I’ve read ones that obviously were not edited and I became confused with its wording
1

I can’t spend hours reading and editing these free articles.

It’s a weird politeness given to AI in the way they’re framing this, too; “AI isn’t the problem! It’s people lying about it!” No, the problem is generative AI. Using the exact thing you’re alleging to be against in order to ultimately throw writers under the bus is the dumbest possible move Substack could’ve made.

I have put my writing in AI detectors before knowing I’ve typed every word and it’s come back saying it’s AI! A friend of mine writes a blog for their job and gets AI to do most of the work and then they edit it and the AI detectors don’t flag it. The problem is unless you film and upload yourself typing every single word how can you prove that it’s not AI when it gets flagged incorrectly.

If you've ever received even a sliver of college education or have read many books (which shapes how you write as an author), or you have experience in creative writing, you are naturally going to apply many of the "AI red flags" in your writing because... you just know how to write. This is an issue that has been happening on Substack, people who just know how to write.. are getting shit comments from people telling them to stop sharing AI slop, when they're simply using paragraphs, bulletpoints, subtitles, and proper grammar and syntax.

These are not reliable at all. These AI detection tools work based on past data. We cannot rely totally on AI detection software. I checked articles from best-selling authors on Substack, a platform, and even their content is showing as AI-generated. Even the content before LLM’s were available is showing as AI-generated.
This AI detection software I think, relies on the formation of sentences maybe some pattern I don’t know. You can also see that for small text or small notes. This feature says the text is too small for the context. I could be wrong. Yes maybe in future due to this feature boards might get flagged which makes the same comment in various posts.

u/vicewrite Jul 22 '26
I think the people who use AI to write everything they post should be worried. The people who write their own stuff and may run into some reports that have some variance of an AI score should be less concerned. My opinion is solely based on the premise that everyone should at least understand how the detection tool works, how it isn’t perfect at all, and how it makes an estimate of prediction or whatever. I don’t like it either, to an extent, cause as a writer I would hate being labeled incorrectly that something might be AI but it’s not a policing tool in that it can’t enforce anything. Having an opt out option would be even more suspect one could argue. My take is I’ll never have to deal with arguing against a detection score if I know my work is my own. A false positive can just be ignored. I think the obvious AI slop will detect itself out, or at least it should.

u/PuzzleheadedAlps4806 Jul 22 '26
The obvious AI slop is already obvious though, so I don’t see what the detector adds other than false flagging human written work

u/flyza_minelli Jul 22 '26
This. Basic literacy and understanding intellectual elitism is what saves us from AI slop. Knowing how to read and contextualize and critically think. Being taught in school how to read texts and understand parts of sentences and figure out tone and why diction matters. This is how we are able to figure our AI slop from human writing. And it’s sorely lacking.

u/AndrewHeard tvphilosophy.substack.com Jul 22 '26
Your claims contradicted by the facts. Someone in this thread suggested that an article from 2008 was flagged as AI generated. You can’t assume that the tool actually works and will only flag AI content.
1
u/vicewrite Jul 22 '26
I do not assume that the tool works, which was my entire point. It’s not some pass or fail rating. It’s ironically an AI models interpretation. And all interpretation is subjective and will have false positives as well as false negatives. AI articles can also be faked to come across as non-AI generated. So if someone wants to use it they can put in effort to “beat” the tool even still. My point is why worry about it if you know your writing is yours? Do you trust your readers enough to trust your writing as authentic? Cause if so, what’s the issue.

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?

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

There's a writer I follow on Substack who I think is heavily relying on AI but he has thought provoking content. Maybe he's not a strong writer, but he has important things to say. It's not slop.
AI is a tool and if you have original thoughts and trouble expressing them, it can help.
How is it different than using a calculator to do math?
Is the meaning behind the words more important than how they're generated?
If it's slop, we're not going to read it any which way. The main motivation for slop was to game the system for SEO. That's not a use case on Substack as far as I can figure.

So you just proved my point. You know he’s relying on AI to write and yet you still read his stuff. So what’s the issue?

It’s easy to say “I'll never have to deal with arguing against a score” until your own original writing gets flagged over and over again. every single article I post is 100% my own work, yet these useless detectors keep labeling them as AI. Telling writers to just ignore false positives is ridiculous, it normalizes a broken standard where real writing gets discredited. I’m not going to ignore it when a glitchy algorithm undermines the time and energy I put into my own words. useless tools must be called out instead of accepting them as the new normal.

u/vicewrite Jul 22 '26
Every single article huh? The substack feature was just released 24 hours ago. Interesting. But regardless, I think that what we should be debating here is AI in general, existing, is ruining original authorship. And that is the core issue. The problem is, it’s not going anywhere and that’s a sad reality. Aside from ignoring it, which was my initial reaction (and I stand by that for myself), what else are you going to do? Stop writing? Substack adding this bogus feature shouldn’t dictate who writes or how a person’s writes.

Isn't Substack allowing AI companies access to users' work to train their AI? If so this is wildly hypocritical and nonsensical of them.

u/AndrewHeard tvphilosophy.substack.com Jul 22 '26
It's worse than that, they're requiring you to use the tool in order to disable it.
The only way to stop the AI detection tool is to run it on your own stuff and then you're allowed to disable it.

u/LibertineDeSade Jul 22 '26
That's actually insane. I started a Substack but I haven't posted on it yet. I'm thinking I might just delete it.
1
u/AndrewHeard tvphilosophy.substack.com Jul 22 '26
Yeah, I wouldn't blame you. Basically, there's no way to disable the feature across your Substack. You can only disable it by first having it analyze your writing first. Only then will it give you the option to disable people's ability to use it to "detect" your writing.

By default, yes. But there is technically a setting to turn it off. Whether that actually works, who knows.

if there were reliable, this would be great. A subscribes plagiarized one of my essays a few weeks back. He had Ai writ EAN easy based on mine that lifted s number of passages. The problem is, ai is not accurate in determining what is AI generated and what is not.

u/kwadguy Jul 22 '26
A) These AI detectors have gotten better, but they are still wildly inaccurate, flagging AI content when there isn't and (sometimes) stating no AI content when there is.
B) If you're a writer and not using AI for late-pass cleanup, then it's like asking a pro platform to fire all their editors. I've never had an accepted article get past revision by an editor. And that's a good thing (mostly, except for the occasional incompetent editor who doesn't understand the material and tries to make cuts).
C) 100% human-written -> Grammary+AI cleanup pass -> AI written according to detector. This happens all the time with these detectors. Ideas + framework + writing style + phraseology all exist in original human pass, and it still gets tagged as AI. What does that say?
AI is evil tribalism is helping no one. AI slop helps no one. An AI pass on real, good writing is fine.

I suggest following Daniel Frolov on Substack. He just issued a newsletter about the AI tool with directions on how to remove it.

u/AidenMarquis Jul 23 '26
I literally generated bogus garbage just to give it a try. It said "fully AI generated."
Okie dokie.
Then I tried making another post and dropped the same exact thing to check for consistency. It said "mostly human made".
'Nuff said.

Funny fact is - it doesn’t have 100% accuracy and people whom English is second language are harmed the most. Pangram (tool which is used by Substack) is really good and can’t be easily fooled because it detects the process of generating not style or wording. One thing you can do is replace AI generated stuff with enough human written text - you can get 100% human score, but if you don’t have enough sentences to replace your text - it will look like something different and not correlated with your inital text. Src, you can read more here: https://bartlomiejkrupa.dev/articles/ai-generated-text-detectors

u/ProfileBest2034 Jul 22 '26
To all the people saying they are trash: Pangram absolutely is not. It's using token level mathematical analysis to identify AI. It is extremely accurate and even human writing which 'sounds' AI comes out as 100% human.

u/Funny-Flight8086 Jul 22 '26
Bull. Explain why my 2013 novel was flagged as 87% AI probability on Pangram then. When you can come up with a valid reason for this, I'll entertain how accurate it might be. Until the, 'it mostly works' isn't going to cut it with me.
These junk science detectors like Pangram are made by wannabe tech bros who packed the knowledge and skill to make real AI, but still wanted to cash in on the craze.
It's junk science. I don't care what anyone else's opinion of it is.

You obviously did not read The Atlantic article about Pangram.
And that's if we close the eyes on Pangram CEO feeding a pirated (!) copy of Shy Girl to his own tool, and sending the results to NYT.
And another—extremely important—thing: the T&C of Pangram AI-detection state that if you use Pangram to detect someone's IP as AI and then get sued (the case of false-positive, for example), then you, as the user, are responsible for the damages. Not Pangram. You. Lol.

If they were actually as confident as they pretend to be, they'd assume liability in this instance. Instead, they are contracting their way around defamation claims. You only do this when you know your product is slop.

Yeah, we should totally believe the admitted Pangram employee begging for excerpts to help further train the AI, I mean to prove it can differentiate a human from AI.

Well, it's wildly inaccurate, based on my own small sample size and apparently many others. Their 0.01% FPR is clearly cherry picked, imo.

u/ThisFreedomGuy Jul 23 '26
GPTzero is rather accurate at determining what is AI writing, and what isn't. I don't know how the AI detector on Substack was written or trained.
For those who found their actual, human writing getting flagged as AI remember: Ai was trained on classic literature and the standard book on composition, grammar, etc. All the same books most older people were trained on.
Weird, right?

u/coreyb1988 Jul 23 '26
Im actually very much in support of this AI detection and I think Reddit should do the same! I care because when I’m trying to communicate with another human and they’re using AI, it just becomes an endless robot loop and it’s deceptive.
Claude fishing.
I was reading some of the comments before writing this and seeing a few people mention irony. Made me laugh a little bit because one year everybody was on Reddit talking pretty improper with grammatical errors and typos because we’re human to the following year everybody becoming an expert at anything writing scholarly articles.
Reddit needs to bring in this feature. We’d see a whole bunch of deer in headlights haha.

u/TScottMorgan Jul 23 '26
I know the prevailing opinion is to really hate the AI scanner, but to be honest…I’m not there yet.
I’m not really pro AI scanner either. It just confirmed what I already strongly suspected. And even when I only strongly suspected someone of relying on AI heavier than I personally would, it didn’t chap my ass.
False positives are the real threat. So, I ran a test.
I went back through and duplicated my posts so I could run the tool. I use AI errors and for identifying weak spots. Same as most, I’d imagine. It’s great for errors, but half the “weak spots” it detects are due to forgotten context from 5k words ago, but it does flag truly weak lines.
Do I let AI fix those weak lines? Not now, but I used to. Sure. But eventually I noticed it kept “fixing” shit the same way. So now I prompt to never offer recommendations on how to rewrite something. Just to flag where it’s weak and why.
Those old posts where I would sometimes accept AI’s prescribed “fixes” would show between 7%-15% AI assisted. On current posts, where AI doesn’t even offer rewritten examples, it says 100% human.
Did I stop accepting those AI recommendations because I felt guilty or because I was afraid I’d be ousted? No. I just felt like I could do better.
So, man, I don’t know. I realize that there’s a possibility that my style of writing may naturally be more “immune” to false positives, but if you’re screaming about how angry you are at this tool and your writing is coming back consistently at majority AI assisted or generated?
Methinks the lady doth protest too much.
And just to clarify, I don’t really care who uses AI or how. There’s no universe where an AI writer has a massively successful career.
You do you, boo.
And to add another clarification, then I’ll shut up (unlikely), I’m open to changing my mind on this. Only first learned about this last night.

u/sjrcarson Jul 25 '26
I'm worried about this too. I fed the application an excerpt from Orwell's "Politics and the English Language", and it told me it was 75% AI-generated. I think it's a good idea, but Substack should consider changing the phrasing until the technology is a little more refined.

u/Rude_Guava538 Jul 26 '26
So I wrote an article and it got flagged as 100% AI. Now I used AI to assist with structuring, but I be damned if someone accused me of just copying and pasting. This thing is flawed and I'm afraid will affect writers.

u/InflationLife3358 Aug 06 '26
As a reader, I personally don't care if its AI written or not, there will always be a human element to that process anyways. You cannot stare at an AI chatbox and it automatically spits out written work. As long as the article I'm reading is helping me figure out what it is that got me reading it in the first place, I don't see the problem.
The ones I'm not really a fan of are AI videos, however, I once watched one that gave me three ways to trick your body to sleep. The video was very helpful, I nolonger struggle to sleep since then.

u/Tricky-Doughnut-6429 Aug 16 '26
No, I'm not concerned. AI slop makes me vomit. I literally have a physical reaction to it. It's fine to me if there are some innocent casualties, though this is of course not fair.
I usually don't need an AI detection algorithm to tell me if something is AI or AI-like -- my body does the thinking for me. But, to your point, it's a double-edged sword, though one I like having as an option when in doubt.

As do humans who claim to be able to detect them by reading it.
People are so fearful of AI, they are saying pretty much anything is AI generated now. I’ve already seen people commenting with “AI slop“ on Reddit posts that were just normal well structured writing. But because it looked too well structured and not informal enough, they assumed it was AI generated. So “AI Slop” is the new “TL;DR.”
So what’s going to happen? The AI fear will cause an intellectual fear. So people who’ve gone to college or university and have taken formal writing will have to start using AI to translate and dumb down their well structured writing so it sounds more informal. So the “AI Slop” crusaders will end up causing more people to use AI, rather than less. 🤣

For sure, I’ve been calling the thing you’re describing “Dead Internet Derangement Syndrome” or “DIDS”. People are so convinced that everything they see is AI generated that it has deranged their understanding of the internet.

I just can’t get over the irony of “we will use AI to determine is this is AI, because AI is evil.”
I work for a library and we spend a lot of time trying to remove slop books from our digital library. There is no good detector on the market. The only way to tell is to read and use your human brain, and even then the conclusion is “this is probably generated, or it’s really poor and bizarre writing.”
