AI Words Checker for Clichés and Writing Tells
Paste English text and run the check. The AI words checker marks 38 familiar moves, from stacked questions to "it is important to note," exactly where they appear. Open the match list to jump back to any sentence. Nothing it finds changes the AI verdict. The phrase scan, hidden-character cleanup, and the AI check are separate tools, and each one sends your text to a Numen server.
Catches 99.5% of AI text at a 5% false-positive rate, scored by RAID, the public benchmark, not by us.
Paste a paragraph or a whole thesis. The iPhone and Mac apps have no word cap and no monthly word budget.

FAQ
AI Words Checker Questions
What does the AI words checker flag?
It looks for a fixed list of 38 phrases and sentence shapes. They include stacked questions, repeated openings, stock transitions, promotional language, and copied chatbot leftovers. The highlight stays on the words that triggered it, so you can judge the sentence yourself.
Does a writing tell prove that text is AI-generated?
No. People use these phrases too. A match points to a line worth reading again. It never changes Slop or Not's AI verdict.
Does my text leave the browser?
Yes. The phrase scan runs in memory on Numen's server and is discarded with the response, so the passage is never stored. Hidden-character cleanup works the same way. The AI check is a separate step and travels to Numen's private Mac server, where the text is deleted after processing.
How is this different from the AI text detector?
This checker points to words from a fixed list. The AI text detector reads the passage as a whole and returns a probability. One can find nothing while the other scores high, or the reverse. Neither proves who wrote it.
Run the Next Check on Your iPhone or Mac
The Slop or Not app checks images and text on-device, so nothing you check ever leaves your device.
