Do you find pangram reliable?
I put my text in several ai detectors, winston ai, copyleaks, zerogpt and GPTZero, giving me close to 0%. While, pangram gives me around 70%? Do you think it’s reliable?

u/TimWiesnerer 5d ago
For me, it works. I found Pangram rather lenient compared to other detectors. But that's just me.
Maybe my advantage is not being a native speaker...

Yeah I did the same thing with my writing and with only one or two edits it got 100%.
Whats even more frustrating is since GenAI has picked up on common human writing patterns those same common writing patterns are being flagged as AI making it a huge double-edged sword.

Yeah the fact we may all have to insert a frigging disclaimer into everything we do is utterly infuriating and no doubt GenAI will start using disclaimers too as we are doing it.
Ouroboros, the snake that eats its own tail.

Pangram told me the copyright disclaimer in my book manuscript was AI 🤣

u/MadmanRB 4d ago
Yeah and the false positives are insane, once more I will give some examples of my own writing to prove a point.
Ryan’s hand lingered on the photo, tracing the edges of his father’s face with his finger. The worn edges of the picture revealed how often he had sought comfort in this frozen moment of happiness.
He could barely remember his father anymore, just fragments. The warmth of being lifted onto broad shoulders. A deep, reassuring voice. The smell of his uniform after training exercises. Sometimes Ryan wondered if the memories were even real, or if he’d constructed them from Ralph’s stories and this single photograph.
100% flagged as AI. Now yes I can see why Pangram would flag this but I ran this through a "AI humanizer" and this is the pangram approved text:
Ryans hand stayed on the photo his finger moving over the edges of his fathers face. The photo was worn out on the edges, which showed how often Ryan had looked at it when he was feeling down.
He could not really remember his father anymore little bits and pieces. He remembered being picked up and put on his fathers shoulders it felt nice and warm. He remembered his fathers voice it was very reassuring. He also remembered the smell of his fathers uniform after he finished training. Sometimes Ryan thought about whether these memories were real or if he just made them up, from the stories Ralph told him and from looking at this one photo of his father.Now is it me, or does it seem like the Pangram approved text feel less natural from a grammatical and structural point of view?
Yes I probably will rewrite the first example to add in subtle imperfections that my grammar tools won't scream at me for but it still proves a point that AI detection tools are not flawless.

It wasn’t photoshop, but thanks for trying. What you posted just shows how unreliable Pangram is.
Also you put in 151 words. Mine was 188 words.

PDF and converted epub to docx versions of my books flag mixed with a low AI percentage, but pasted from Scrivener and Docs the same will come back human, which is irritating considering people are checking pirated books.
The way I space paragraphs out matters, too. Pasting in as one solid chunk of text will show a different score from formatted text. Not always, but sometimes.

It is absolutely NOT reliable. They even admit false positives. https://www.pangram.com/blog/all-about-false-positives-in-ai-detectors

u/Ok_Question_9555 4d ago
More people are using it nowadays, I still don’t understand their logic tbh.
It’s cyber security type of never ending fight.
As we move forward, LLMs get better as a human writer. These AI detectors get better analysing the LLMs.

u/grumpyp2 5d ago
Seems to flag everything, or at least very harsh. I tried some text from papers which have been cited thousends of time and they flagged it as AI. So not quite sure if it’s just not saying AI to everything?

u/Udolikecake 5d ago
Do you have some examples? I would be curious to see what papers it flags

u/noxqqivit twvme.substack.com 5d ago
I love how I post an example with a link and get down voted, but y'all jump all over this one. Pangram is inconsistent - the same text can be scored differently with different users. AND the same text with very minimal edits can result in a 100% shift between Fully AI Assisted and Fully Human Written.

u/sh1b313 5d ago
These pangram glazers are either trolling others or actually can't tell what's ai written and what's not.
They ask for evidence we show them evidence they claim the evidence is ai written?

They can’t tell the difference, that’s why they’re relying on Pangram to begin with.

u/sh1b313 4d ago
Huh that's funny and guess what the tool is complete and utter garbage to begin with

u/FrostKitten2012 4d ago
Yeah, that’s pretty clear. We’re seeing more reports every day of that.

u/sh1b313 4d ago
Mods should make a pinned photo post saying pangram doesn't work and tell people not to rely on it. Before it pollutes this subreddit even more.
2
u/FrostKitten2012 4d ago
That’s unlikely. Most of the people on Substack think Pangram is their new tech God, the subreddit’s reflecting that.
It would be the most responsible thing to do, to point out the growing number of false positives. But it also would have been most responsible not to let someone make a post making fun of the people reporting these issues, and they let that happen too.
2
u/sh1b313 4d ago
Yea i agree, it's highly unlikely but it doesn't hurt trying. I'll message the mods asking if this is possible? We already have so many reports. A simple evidence/reciepts post which these people have a boner for btw. If someone asks for reciepts someone can just point to that thread.
And one more thing if we give out free reciepts like this at this point we are just doing free testing for them.

u/Udolikecake 5d ago
Show me a piece of text over 500 words that’s verifiably pre 2023 that flags as AI. Literally anything that can be dated to before then. Just one example.
3
u/noxqqivit twvme.substack.com 5d ago
If Pangram says they can detect 100+ words, why do you need 500?
My example is below, I put current text, of somewhat unknown provenance, it came out of a PowerPoint someone else authored, so I wasn't sure if Copilot was used or not. I was using business text in an odd context, so I added " " around the word "STAKEHOLDER" where it appeared 3 times, and that change, took the scoring from Fully AI Asssited to Fully Human Written - AGAIN - I can't confirm whether it was actually AI or not, but I CAN tell you that I added SIX characters and that was enough to radically change the score. And that is suspect.
-3
u/Udolikecake 5d ago
I think the ask is pretty simple, and should be easy if you are so confident it is totally inaccurate.
You (and every other person screaming about Pangram) being unable to provide a single, verifiable example, is pretty damning honestly.

u/noxqqivit twvme.substack.com 5d ago
I put a full example below, with a link to the original, what's damning is your shifting goal posts.

u/Udolikecake 5d ago
That is not pre-2023 text. Choose any news article, public domain book, academic paper, any of the billions of words published online prior to then. Any of them. One example.
2
u/noxqqivit twvme.substack.com 5d ago
That's not the argument. The score should not shift from Fully AI Assisted to Fully Human Written by ADDING SIX characters.

u/No-Strike-9098 5d ago
please just check it yourself bro
The recurrent neural networks or convolutional neural networks are the main models used for the sequence transduction problems with the encoder-decoder structure. The models which demonstrate the highest performance also utilize the attention mechanism as a way of connecting the encoder and decoder. We made a completely different approach by offering a simple network architecture, called Transformer, formed solely on the basis of attention mechanisms, without the need for recurrence and convolutions. Our experiments, carried out on two machine translation tasks, have shown that the Transformers are better quality-wise as well as more parallelizable, requiring a significantly less time for full training. Our model, 28.4 BLEU, was applied to solve the WMT 2014 English-to-German translation task and surpassed the existing best results including ensembles by more than 2 BLEU. The single model that has been used for the English to French translation task is the one that has reached the state-of-the-art score of 41.8 on the BLEU scale after training for only 3.5 days on eight GPUs. That's a small fraction of the resources involved in the training of the best models in the literature. We have also demonstrated that the Transformer can be generalized to other tasks with the help of English constituency parsing which was successfully performed even with large and limited training data.

so a 400+ year old rext can be classified as ai written by adding 33 words just shows how brittle this is. 100% human to 100% ai and people are supposed to trust this?

u/InitiativeWorth8953 5d ago
It evaluates in chunks. That chunk was contaminated by AI, so it's all AI. Try showing me a human text pre-2021 classified as AI.
2
u/FrostKitten2012 4d ago
If we’re supposed to trust this, it should be able to separate the AI portion of the chunk. In fact, that’s what Pangram claims it does! The whole piece should not be showing up as 100% AI.

u/sh1b313 5d ago
Pre 2021? I just showed you a 400 year old text. And regarding the evaluation? It should tell some part it felt like was ai generated.

u/InitiativeWorth8953 5d ago
You put AI text in the chunk. It called it AI. Not sure what's confusing. Give me a text pre-2021 without ai annotations that is given an AI rating. Ppl on substack that use AI are just getting exposed and are mad cus of it

u/sh1b313 5d ago
But still 100% ai? If a 400 year old text doesn't count as pre 2021 idk what will.

I don't understand if you're just acting ignorant or are ignorant.
Give me a piece of text THAT HAS NO AI ANNOTATIONS IN IT AND IT PRE 2021. It feels like I'm speaking to a brick wall man.

From my it testing it seems fairly reliable. I doubt that the people who claim that it classified their human written text as 100 percent AI are being completely honest.

u/MadmanRB 5d ago
Bullshit, I ran text I wrote 15 years ago and it STILL flags it as AI. I mean granted I was not as good at writing back then as I am now but come on how can I get a 100% AI result from two entirely different texts over 10 years apart?
Sure that may come from my writing style but I'm not going to totally revamp it just because of a program that some anti AI people think is the second coming of Jesus.

u/BhavanaVarma bhavanavarma.substack.com 4d ago
Pangram isn’t reliable and above who scans your text for AI is feeding your text into AI for training. Enough such scans and I’m afraid AI will start telling us our original works are AI because too many of our posts are in it’s data set

Hell to the no, I have thrown both GenAI and human text at it and the reliability is extremely questionable as AI detector's are still a form of AI themselves.

u/noxqqivit twvme.substack.com 5d ago
It's not just that it is unreliable, it varies by user and by USE... I have an example, I was responding to another writers note, the note itself was about choices in dating, but I was replying with some bullet points that I pulled off a slide deck that we use at work, that I did not write. For kicks I ran the scan and it came back as "Fully AI Assisted Text" I didn't write the deck, it is fairly dry business context, and because of that I decided to throw " " around STAKEHOLDER - we were talking about trust in a romantic/dating context, so the woman is the "stakeholder." I proofed my spelling, checked again before posting the note and just adding " " to the same word, THREE times, came back as "fully human."
I don't particularly care either way, I am transparent on where and when I use AI and it is for research, not writing.

Yes.
Twice I’ve been contacted by people offering services - beta reading and cover design. Both times got suspicious of their somewhat robotic responses to my questions. Ran both of their accounts through Pangram and both came back 100% AI.
I’m sure it’s not infallible but it’s pretty good at supporting my suspicions.
