How the quiz works

Each round puts two short paragraphs on the same topic side by side, anything from a commute to a first dog. One is the plain original. The other is an AI rewrite of it. Pick the one you think AI wrote. The answers come at the end, with a breakdown of every round.

To make the AI versions, we asked GPT-4.1 mini to make each paragraph more sophisticated and articulate, three passes in a row. We never told it to add AI phrases, so the tells you spot came out on their own. We also trimmed each AI version to match the original's length, so picking the longer paragraph won't help.

Your score comes in two parts: how often you caught raw AI, and how often you caught AI that went through UnslopAI first. The difference between the two is what the engine does.

Readers can tell

Everyone asks the same few models, and they hand back the same paragraph. Read enough of it and the patterns jump out: the same words, the same rhythm, the same tidy wrap-up.

That is a problem when you only used AI to fix your grammar. Your draft now reads like everyone else's. UnslopAI edits those patterns out, so readers don't clock it at a glance.

The quiz above is the honest test. Half of the AI paragraphs are raw. The other half went through our engine first.

Questions

Usually big words for small things, with a neat little lesson tacked onto the end. Rhythm is the other clue: every sentence runs about the same length. Our post on the phrases that make AI writing easy to spot goes through the common ones.
A game is 10 rounds. Half of them use raw AI and half use AI that went through our engine, in random order.
Only as anonymous totals. We count how many paragraphs players caught so the numbers on this page stay current. No account, name or email is attached.
UnslopAI finds machine-typical phrasing and cuts it. It then fixes the rhythm and checks that the meaning survived. You can try it on your own draft, and the first five rewrites are free.
