Free AI paper checker for research and term papers
Paste or upload a paper and see how likely it is that AI wrote it. Check your own work before you submit, free and private.
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 paper checker 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 your paper against the patterns of AI writing and human writing, section by section.
Read the score
You get a number from 0 to 100 and a plain read on how likely AI was involved.
Built for longer papers
Research papers, term papers and reports are long, so the checker splits the text into sections, scores each one, and averages the result. That keeps a single dense or formal passage from throwing off the overall reading. Paste the text or upload a Word or PDF file.
What a high score means for a paper
Academic writing is formal by nature, and formal prose can read as AI even when it is entirely your own. Treat a high score as a prompt to revise the flagged sections in your own voice and to double-check quoted or summarized material, not as an accusation.
Where your paper goes
The check happens in memory on our own server. As soon as you have a score, your paper is dropped. No logs, no database, no training set.
There is no account holding a history of your checks either.
