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?

The phrase scan itself stays in your browser. There are two separate server tools on the page. Hidden-character cleanup sends the passage to Numen's cleanup API, which handles it in memory and does not store it. Submit the passage for the AI check and it goes to Numen's private Mac server, then 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.
