AI detection tool
Don't. It's not possible to make one that's unbeatable, no matter what companies say. They're not worth using. If you suspect AI writing, ask questions about the content or word choice. Follow up questions will immediately reveal a lack of content knowledge. If it's creative writing ask them to explain what certain words mean, or ask false questions about things they didn't actually 'write' to catch them in a lie because most won't even read it properly or remember what the AI wrote. You're better off considering it as work written by another person and using methods to catch that out. More on reddit.com

AI detection
There are no reliable AI detectors. Questions to consider: Does the work fail to meet standards anyway? AI work is often vague and sound-same-y, so it probably doesn’t actually meet the prompt. Does the work match your student’s voice, style, and prose in other works they’ve completed? More on reddit.com

“AI detectors are useless,” “if you use AI checkers you’re punishing innocent students,” and other claims I don’t quite buy
My students literally can't even manage to use AI well. They leave it with the weird grey highlighting that chat gpt uses, they use tons of vocabulary words way above their level(I teach EFL, verbally you can't remember what for example means, don't claim you naturally used the word precipitous), or include the telltale line "I am an AI language model...".

Best AI Checkers for Teachers in 2025
February 11, 2026 - By regularly interacting with AI, you can quickly identify formulaic structures, verbosity, or unnatural language. Examples of stylistic elements to pay attention to include the overuse of passive voice, repetition, and generic statements, as well as syntactic and orthographic perfection which often lacks a human touch. There are several AI checkers out there, I have tested a number of these tools and came up with this list. To test these AI detectors, I create two types of text content: one I have written myself, 100% human written (around 500 words), and the second one I generated it using ChatGPT 4o.

r/teaching on Reddit: What AI detectors are your schools using and what’s the threshold they consider “AI-written”?
October 15, 2025 -

Hey Teachers,

I’m curious how different colleges & schools are handling AI writing detection right now.

• What detector(s) does your institution rely on (Turnitin.com, GPTZero.me, IsItAI.tech, Copyleaks.com, Originality.ai, etc.)?

•Do you share with students what “percentage” or “score” you treat as suspicious or AI-written?

•And how accurate do you find it in practice?

I’m trying to understand how consistent (or inconsistent) these detection systems are across schools. Seems like the results vary a ton. Would love to hear what your department or admin actually uses and how they interpret the numbers.

For reference my wife’s course uses a flat 20% above Turnitin AI score to request a resubmit.
