The Short Answer
You cannot be 100% sure that a text was written by ChatGPT. But AI writing leaves habits, and once you know them they are easy to spot. Here are ten of the most common signs.
10 Signs Text May Be Written by AI
- 1
Overused AI words
Words like "delve", "tapestry", "realm", "testament", "pivotal", and "multifaceted" show up far more often than in normal writing.
- 2
Stiff transition words
Many sentences start with "Furthermore", "Moreover", or "In conclusion", even in casual text.
- 3
Flat sentence rhythm
Almost every sentence has about the same length and shape, so the text reads like a metronome.
- 4
Lists of three
Ideas often come in neat groups of three, such as "fast, simple, and reliable".
- 5
It repeats your question
The first sentence often restates the topic instead of getting to the point.
- 6
Hedging phrases
Lines like "it is important to note" and "it is worth noting" add words but no information.
- 7
No real details
The text sounds right but has no names, dates, numbers, or personal stories.
- 8
A generic ending
The last paragraph repeats the points and ends with a tidy, general summary.
- 9
Perfect but bland tone
The grammar is flawless, yet there is no opinion, humor, or voice.
- 10
Messy formatting from the chat
Stray asterisks, pound signs, curly quotes, or invisible characters can be left over from pasting a chat reply.

How to Make AI Text Sound More Human
