Free AI detector for teachers and educators
Paste or upload a submission and get an AI-likelihood score in seconds. Free, private, and built to inform a conversation, not end one.
Check your textHow to read your AI detector score
The AI detector gives you a single number from 0 to 100. It is the estimated chance that AI wrote the text, not a yes or no. Here is what each band means.
Probably a person
Reads like human writing. We did not pick up the patterns a model tends to leave behind.
Hard to say
Some of it leans one way, some the other. Read it yourself before you draw a conclusion.
Probably AI
This has the marks of machine-written text. Read it closely before you conclude anything.
How the AI detector for teachers works
Three steps, a few seconds, no setup.
Add your text
Paste it, upload a Word or PDF file, or drop in a link to the page you want to check.
We check the patterns
The model weighs the writing against the patterns of AI text and human text.
Read the score
You get a number from 0 to 100 and a plain read on how likely AI was involved.
How to use it responsibly
A detector score is a starting point, not a ruling. Honest students sometimes score high, and AI text that has been edited can score low. Treat a high score as a reason to look more closely: compare against the student's earlier work, ask about their process, and talk it through. Never grade or accuse on a number alone.
What ai detector teachers use
Many schools rely on whatever is built into their learning platform, often Turnitin, which teachers see at submission time. A free standalone checker like this is handy for a quick second read on a specific piece, or when you do not have an institutional tool to hand.
Why scores can mislead
Detectors read statistical patterns, not intent. Second-language writers, very formal prose, and tightly structured answers can all read as AI when they are not. Keep that in mind before raising concerns, and give students room to explain.
Where your work goes
The check happens in memory on our own server. As soon as you have a score, your work is dropped. No logs, no database, no training set.
There is no account holding a history of your checks either.
AI detector for teachers FAQ
Is it free for teachers?
Yes. No account, no limit on how many submissions you check.
Can I rely on the score?
No detector is reliable enough to accuse a student. Use it as one signal among several.
Can I upload student files?
Yes. Upload a Word or PDF, paste the text, or drop in a link.
Will it flag second-language writers unfairly?
It can. Formal or non-native writing sometimes reads as AI, so always confirm before acting.
Do you store student work?
No. It's analyzed in memory and dropped as soon as you get a score.
