Quillbot ai detector
Quillbot's hit or miss tbh. sometimes it just swaps words and still sounds robotic. I've had better luck with walter writes ai, feels more like it's rephrasing how a real person would talk, not just thesaurusing stuff. More on reddit.com

Does using Quillbot make your work detectable for AI or plagiarism?
lecturers have said that student’s putting in their own work into plagiarism detectors can get flagged on turnitin. Technically true: you have to check what rights you are giving up by putting your work into free detectors - like some AI programmes they might keep your work in a database. If that database is shared with turnitin or other plagiarism software then it might flag your essay as plagiarised, because it's coming up as similar to the work you've inadvertently deposited in the free detector. I don't believe that Grammerly or Quillbot have an agreement with turnitin so in this case you're probably fine; however, you shouldn't need to use them to detect plagiarism. You wrote the essay, so you know if it's plagiarised or not. If you quote someone else, then put in quote marks and give a citation; otherwise use your own words, don't rely on stuff like grammerly to write it for you, and you'll be fine. More on reddit.com

Is quillbot accurate for AI detection?
honestly quillbot’s kinda mid for that tbh. like it’s good for rephrasing but not for actually humanizing the tone. ai detectors like GPTZero or Turnitin look for deeper stuff like rhythm, predictability, and burstiness, not just swapped words. i’ve been using Walter Writes lately (it’s one of the best AI humanizer tools i’ve found) and it makes writing sound way more natural, like someone actually typed it. makes it a lot easier to bypass detection without killing the flow. if you’re tryna make your stuff undetectable, that’s a better move imo.

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 😭😭
