I'm not kidding I've been thinking about writing a similar post the last few hours. I had ChatGPT provide me with an outline to structure my essay based on key points I wanted to focus on. Then I wrote the paper myself. Every other AI detector is reporting back 100% human text. For some odd reason, quillbot is telling me anywhere from 33-60% in random sections I wrote on my own. Feel like I never should have checked anyways and was just being paranoid. Now I'm worried I'm totally screwed. Answer from Deleted User on reddit.com

r/ChatGPT on Reddit: Quillbot ai detector
May 7, 2025 -

I have two essays due and I was wondering if anyone else has had similar issues with quillbot

Since it’s an important essay I’m checking if it’s ai generated but I do this in chunks of 200 words because if I put in the whole paragraph it always says no ai detected

Should I trust it when I put it in full paragraph or in parts ?

I try to change the bits marked by ai but sometimes it just says that my edits make the rest of it sound like ai instead of just saying no ai was used n getting worried cus I made a small change n it went from 20% to 60% n I was like wtf 😭😭

I’m not talking about the paraphrasing tool, rather the free AI detector, and using Grammarly to detect plagiarism. I don’t have access to turnitin (only the staff do I think?) so I can’t actually see how much work is plagiarised or not, but lecturers have said that student’s putting in their own work into plagiarism detectors can get flagged on turnitin.

I just wanna know if that’s a myth or if it’s actually true

August 17, 2024 -

I am at a loss here. For background, I am not an English native speaker. Writing in English has always been a bit awkward for me. Grammarly and Quillbot have been a blessing.

The issue I am having is this. I am writing an analysis for my first assignment. I wrote the whole thing. I obviously paraphrased from the source material. I got curious and put it through Quillbot's AI detector. Imagine my surprise when it said that it is 100% AI generated. Once I put it through Quillbot paraphraser, it lowered it to 58% AI generated.

I don't know what to do here. Beyond lowering my own standards of grammar, which I am not going to do, I am afraid that a professor might think I am cheating.

Is there anybody else having this issue or experienced this? Am I overthinking this?

May 5, 2024 -

I wrote an essay about AI replacing jobs. I'm not the brightest guy ever and i'm average compared to my classmates but I barely use AI on any school work.

I put the essay in quillbot's AI detector, and oh man it's 42% AI. I've never even opened my ChatGPT app the whole day, nor did I open any type of AI writing website.

Now my teacher is calling me out for supposedly using AI on my work. I even said to him to try and detect my AI work on other websites and would you look at that, almost all of them showed near 0% AI except one that showed 60%

Honestly, I hate when this happens. Are there some things I should do to clear "AI" on my works? I don't use AI detector on my work before passing them because I am 100% certain that it is not and I definitely wrote it without ever using any type of AI.

Turnitin explicitly advises not to use its tool against students, stating that it is not reliable enough: https://help.turnitin.com/ai-writing-detection.htm “Our AI writing detection model may not always be accurate (it may misidentify both human and AI-generated text) so it should not be used as the sole basis for adverse actions against a student. It takes further scrutiny and human judgment in conjunction with an organization's application of its specific academic policies to determine whether any academic misconduct has occurred.” Here’s a warning specifically from OpenAI: https://help.openai.com/en/articles/8313351-how-can-educators-respond-to-students-presenting-ai-generated-content-as-their-own This paper references literally hundreds of studies 100% of which concluded that AI text detection is not accurate: A Survey on LLM-Generated Text Detection: Necessity, Methods, and Future Directions https://arxiv.org/abs/2310.14724 And here are statements from various major American universities on why they won't support or allow the use of any of these "detector" tools for academic integrity: MIT – AI Detectors Don’t Work. Here’s What to do Instead https://mitsloanedtech.mit.edu/ai/teach/ai-detectors-dont-work/ Syracuse – Detecting AI Created Content https://answers.syr.edu/display/blackboard01/Detecting+AI+Created+Content UC Berkley – Availability of Turnitin Artificial Intelligence Detection https://rtl.berkeley.edu/news/availability-turnitin-artificial-intelligence-detection UCF - Faculty Center - Artificial Intelligence https://fctl.ucf.edu/technology/artificial-intelligence/ Colorado State - Why you can’t find Turnitin’s AI Writing Detection tool https://tilt.colostate.edu/why-you-cant-find-turnitins-ai-writing-detection-tool/ Missouri – Detecting Artificial Intelligence (AI) Plagiarism https://teachingtools.umsystem.edu/support/solutions/articles/11000119557-detecting-artificial-intelligence-ai-plagiarism Northwestern – Use of Generative Artificial Intelligence in Courses https://ai.northwestern.edu/education/use-of-generative-artificial-intelligence-in-courses.html SMU – Changes to Turnitin AI Detection Tool at SMU https://blog.smu.edu/itconnect/2023/12/13/discontinue-turnitin-ai-detection-tool/ Vanderbilt – Guidance on AI Detection and Why We’re Disabling Turnitin’s AI Detector https://www.vanderbilt.edu/brightspace/2023/08/16/guidance-on-ai-detection-and-why-were-disabling-turnitins-ai-detector/ Yale – AI Guidance for Teachers https://poorvucenter.yale.edu/AIguidance Alabama - Turnitin AI writing detection unavailable https://cit.ua.edu/known-issue-turnitin-ai-writing-detection-unavailable/ The MIT and Syracuse statements in particular contain extensive references to supporting research.

I wrote an assignment paper on my own but used Grammarly's suggestions and GenAI tool, and ChatGPT to frame sentences properly. Then, I used Quillbot's AI detector tool to see if there were excessive traces of AI in certain parts of my paper. My University doesn't have any problem in using AI for writing papers and I have taken care of citing the sources properly. My concern is, however, does uploading my work to Quillbot's AI Detector get it indexed somewhere on the internet, which may consequently result in plagiarism? Does anyone have an idea about this?

I just started a new job. During. interview, they mentioned that I needed to pass my work through AI detector tools. Okay, no big deal, right? Since Im already writing everything myself, it shouldnt be too much of a problem.

Hoo boy was I wrong!

Day 1, wrote my copy, passed it through zeroGPT, 30% AI content. Okay, I will rewrite a few sentences, no problem. Content sails through, everybody's happy.

Day 2, they liked my writing on day 1, so I was given more work. They were short blogs, around 450 words each; completed all of it, went to check it through the damn AI detector, BOOM. 80% Ai. 100% AI. 69 FUCKING PERCENT AI!

What is the damn detector even going to detect when I have typed every single word, why my own two hands!?!??! The fuck is going on? I spent 2 hours trying to 'humanize' my ALREADY HUMAN work to appease AI fucking Christ.

Oh and I put it through multiple detectors, Copyleaks, Quillbot, ChatGPTs own AI detector. The fun part is that each detector has its own damn opinion of how much of my content is AI written. One says 69%, other says 50, and yet another says 12.

I swear AI is going to be the end of humanity.

So, I’ve got a lot of positive feedback about my recent post Humanize AI. Reddit users seem to enjoy reading the truth and not just promo. Besides, that’s my actual hobby - apart from data recovery. That’s why I decided to write a decent tutorial about AI writing detectors (AI Content Checkers) and review the best ones like: GPTZero, ZeroGPT, Turnitin AI Checker, Grammarly AI Checker, Quillbot AI Checker, Scribbr AI Detector, and others. We’ll do a real test to see if they’re fake or not and whether it’s possible to bypass AI detectors nowadays. I even generated a ChatGPT image using the latest model for this post. Let’s go!

Here are the 11 best and most popular (not sure best) AI checkers I want to test: (How did I check popularity? I simply used SEO tools to estimate their traffic and sorted them by that. If any AI detectors are missing here, it’s because they don’t work, users don’t like them, or they’re not investing in marketing, haha, so… sorry!) If you want to avoid high detection and humanize ai content - read my tutorial How to Humanize AI & Best AI humanizers Best AI Humanizers with proofs reviewed here: https://www.reddit.com/r/DataRecoveryHelp/comments/1oqwdib/best_ai_humanizer 🎁 If you need to Humanize AI right away try this: https://aihumanizer.net - 100% Free Ai humanizer (nice human score in ZeroGPT & GPTZero, simple language) https://www.zerogpt.com/ - ZeroGPT Checker (My top choice. Easy to fool when you rewrite content in a conversational style.) https://gptzero.me/ - GPTZero AI Detector (Very inconsistent results. Since the September update it has become unstable - some texts score 0%, others 100% AI, with no clear logic.) https://quillbot.com/ai-content-detector - Quillbot AI Checker (Works fairly well. Can be fooled by using natural language and avoiding a rigid, formal tone.) https://www.scribbr.com/ai-detector/ - Scribbr AI Detector (Just an iframe of Quillbot’s checker.) https://www.grammarly.com/ai-detector - Grammarly AI Checker (Very weak detector, easy to trick.) Less popular AI detectors: https://originality.ai/ai-checker Originality AI Checker (Feels scammy. Almost always shows 100% AI, but if you add intentional errors it marks them as human. Very odd.) https://undetectable.ai/ Undetectable AI Detector https://decopy.ai/ai-detector/ Decopy AI Detector https://notegpt.io/ai-detector NoteGPT AI Detector https://copyleaks.com/ai-content-detector Copyleaks AI Detector https://gowinston.ai/ Winston AI Detector I would not review each pros and cons and plans intentionally. Who cares? You can look yourself. I will only get scores before and after and share with you. Reddit allows you to attach only one image per post, so, sorry! What AI detector do colleges & students use? It’s definitely Turnitin AI Checker. There’s no free way to check it without registration. I tried, and it asked whether I’m a student, instructor, or teaching assistant. I didn’t want to lie, so I quit. But I’ve read a lot of Reddit discussions, and both students and teachers give the same answer to the question: “How accurate is Turnitin AI Detector?” The simple answer: Not accurate. Haha! Lots of false positives and easy to manipulate with special prompts. Ok let’s do a simple test of the rest popular best AI detectors and checkers: For this test, I’ll generate a simple essay titled “What is an AI Detector and How Do They Work?” (500 words). Then I’ll show you the score before and after some basic humanization using simple prompts.I’m intentionally skipping web-based AI humanizer tools because I already covered those in this tutorial.I’ll use ChatGPT 4.1 Mini – fast and cheap. I assume a lot of writers and students might be using this specific model.

What is the most accurate AI detector & how does an AI detector work? I have a short answer for you already: not even close to accurate! Because there’s no single algorithm that can make a text 100% AI or 100% human. It’s all about patterns. But those patterns are often what real people use too. Besides, you can easily create a prompt that breaks the patterns. OK, let me give you a basic understanding of how an AI detector actually works: Think of it this way - when an AI writes, it tends to be super predictable and efficient with its word choices. It’s like a really smart, but sometimes boring, student who always picks the most statistically probable answer. Humans, on the other hand, are messy! We use quirky phrasing, vary our sentence lengths, and sometimes throw in unexpected words or even make “mistakes” that an AI wouldn’t. AI Detectors with Their Own Model AI detectors look for these differences: Perplexity: How "surprising" the next word is. Humans tend to have higher perplexity because we're less predictable. Burstiness: The variation in sentence length and structure. Human writing is like a rollercoaster. AI writing can be more like a flat road. Repetition: AIs might repeat phrases or structures more often. Stylometry: They analyze things like average sentence length, vocabulary richness, and even punctuation habits. They then feed all this data into a machine learning model, which has been trained to recognize the "fingerprints" of AI versus human writing. It spits out a score indicating the likelihood of AI involvement. AI Checkers Using Other Model APIs Some fake AI detectors don’t have their own model at all. All they do is ask another AI whether the text looks like it was written by AI or not. It’s a very expensive method (because you pay API credits every time) but literally very cheap to develop. All you have to do is choose the cheapest API and get results instantly. But here’s the catch - I tried this tactic, and it gave me about +-50% accuracy, haha! That’s crazy! That’s why I’m sure you’ve noticed the same content sometimes gives you a different score over and over again. Here’s another example: some AI detectors use their own basic scripts - like checking whether the content has a closed em dash or not, or if there’s phrasing like “dive in,” “in the digital era,” or “digital landscape.” If they find these words or combinations, they simply mark the content as 90% AI. Stupid? Oh yes! Are AI Detectors Reliable? I’ve tested a bunch of AI detectors, and here’s the deal: none are 100% reliable, not even 85%. Even the best ones only hit about 70–85% accuracy – and that’s in perfect conditions. Free tools often do worse. False Alarms Happen Sometimes, detectors flag real human writing as AI. This is especially true for non-native English speakers or overly structured writing. I’ve seen stuff like the U.S. Constitution get marked as AI! They Miss Stuff Too On the flip side, newer AI like GPT-4.1 can often slip by undetected, especially if the text has been edited a bit. So yeah, AI-written content can fool detectors more than you’d expect.

r/AskProfessors on Reddit: Will Turnitin AI detection Detect Quillbot if I Used it on All of my Assignments?
May 13, 2024 -

I have multiple learning difficulties and I am studying at a UK university as an international student, given the background I found struggles with writing High quality papers and using correct terminology to paraphrase. I have been using Quillbot for a few years (Before it became "cool"). I would usually paraphrase a few sentences and then manually choose words I deemed to be better fitting, of Course providing proper referencing when inserting the text into my document. This way I could find better words to use and get more consistent text without using same words over and over to describe certain things. I had never had issues with it and I have even received compliments from lecturers on my writing style.

With recent hike in AI academic misconduct our university has introduced strict policies that ban the use of AI tools. However when I spoke to Students Union employee about this, I was told that Turnitin is also using old submissions to flag inconsistencies in writing styles. With that being said I feel trapped between Using Quillbot the way I did for all my assignments and risk AI detection or Use dictionaries to find synonyms to use, but risk being flagged for inconsistent writing style.

I used AI Detectors to check if my old submissions would be flagged and certain sections were detected as AI written. I am not sure what to do and I am not even sure who I should talk to at university without being considered as cheater.

I will be thankful for any advice!

r/ChatGPT on Reddit: HELP. Is all my work lost? AI Detector shows 100%
April 18, 2024 -

Hello everyone,

I don't know if it's my ADHD and because i have been hyperfocused on this problem since this morning, but I'm feeling sick to my stomach. Let me give you some context. I've been working on my thesis in a social science field for 7 months. My topic is super niche, and the research was exhausting with very few sources available. I did extensive research and included significant original research.

Here's the problem: I come from a non-academic household, and ChatGPT has been incredibly helpful in addressing my uncertainties. My work involved asking ChatGPT for ideas on how to proceed with my analysis, and if I liked a suggestion, I incorporated it. I often wrote my thoughts or sentences into ChatGPT and had it help me refine or clarify them. I rarely accepted suggestions directly without further commenting and critically questioning them, maintaining a "dialogue" with ChatGPT throughout.

Today, for some reason, I decided to check my work with AI detectors by sending in some paragraphs. Most detectors indicated a 20% to 50% chance that the text might be AI-generated, which didn't worry me much. But then I tried Quillbot, and it flagged many parts of my text with a 100% chance of being AI-generated. I'm at my wit's end. No matter what I change, the result is always the same: 100%. When I insert other academic texts, it shows 0%, but with my thesis, it’s 100% every time. It’s driving me crazy.

I've tried paraphrasing myself and using humanizer AIs, but the result is always the same: 100% likely AI-generated text. I'm at the end of my rope. Are over 6 months of work down the drain? Is there any way out of this? I've even started reading research papers on how to evade AI detection, but Quillbot always marks my text as 100% AI-generated. Should I just ignore this program?

I know there have been many posts here saying these detectors are unreliable, but the result makes me very nervous, and essentially it is true that the text was written with the help of AI. Please be kind, I'm too exhausted for criticism. I need to know how i can recover from this and what are my options to procceed.. any advice is deeply appreciated.

Thank you

You are definitely overthinking. AI detector is fundamentally bullshit because AI learns from actual human language. Just focus on building value, and use AI as a tool to build your own point of view. If someone rejects your work saying its AI made, state that while AI was used, the interaction between your own intellect and the AI was crucial for the high quality of the end result. If still rejected, ask for factual proof that the text was partially or totally generated by AI (which is impossible), also, you can always sue. I think whoever invalidates an idea based on suspicion of AI use is profoundly lacking understanding of the technology and it’s potentials.

This is something I start to fear about out society regarding AI. I start feeling a persecution against the use of AI as if it was cheating or something highly immoral. An example is instagram that is making mandatory to flag if q given content is created with AI and displays it clearly. Even if the user don’t flag it, they will eventually detect and flag if themselves. I see on photography communities, photos that have been edited with the hell of AI tools becoming absolutely discredited. Wattpad, a platform for book publishing is banning books that are detected as containing any AI generated content. By any, I mean even the cover image or any illustration. This happens despite the focus of the platform being the writing and the images being only complementary!! Come on, AI is a tool we are supposed to help us enrich our work. It someone uses it to enhance a phrase, to explore ideas, what’s wrong?! If someone just let the AI do all the work by himself will naturally end up having it full of incoherences and the result will be very poor. At least for now. There is no need for verification tools, if the outcome of using AI has good quality and is accurate it only means the author used it correctly and had the knowledge needed to validate all the information. Let’s stop being picky about the use of AI
