Human or AI? Can you tell who wrote it?
Read each passage and guess whether a person or an AI wrote it. After every guess you see the tells that gave it away, the same signals AI detectors look for.
“In today's fast-paced world, the importance of time management cannot be overstated. By prioritizing tasks effectively, individuals can unlock their full potential, foster meaningful growth, and navigate the complexities of modern life with confidence and clarity.”
How to tell if something was written by AI
AI writing is fluent but safe: it picks the most likely next phrase, so it reaches for the same openers, verbs and sentence shapes again and again. These six tells cover most of it.
- Stock openers
- "In today's fast-paced world", "In the ever-evolving landscape of".
- Inflated verbs
- Delve, foster, unlock, navigate, leverage, underscore.
- Lists of three
- Every sentence lands on a tidy triplet: "clarity, confidence and connection".
- No specifics
- No names, numbers, places or dates, so nothing in it can be wrong.
- Even rhythm
- Sentences of similar length and shape. Human writing lurches between short and long.
- The tidy closer
- "Ultimately", "In conclusion", "It's not just X, it's Y".

Questions
Look for specifics and irregularity. Human writing names real places, numbers and people, takes risks with sentence length and has opinions. AI text leans on stock openers, abstract verbs like foster and navigate, lists of three and a neat summary line. No single signal is proof, so read for several together.
Sometimes, on raw model output. On edited, formal or non-native English writing they make frequent mistakes in both directions, which is why a score alone should never decide anything. Detectors that show which sentences they flagged, and why, are far easier to check.
The human passages are public-domain excerpts from published books, credited after each guess. The AI passages were generated by a language model for this game.
