What is AI-generated content?

AI-generated content refers to any text, image, video, audio, or other media created by artificial intelligence rather than a human.

For written content, AI-powered tools like Grammarly, ChatGPT, and Gemini generate text by analyzing vast datasets and responding to user prompts. These tools can produce fluent, well-structured copy that mimics human writing with impressive accuracy.

AI excels at organizing ideas, enhancing readability, and streamlining content creation, but it often lacks personality and creativity—things that make human writing feel, well, human.

Characteristics of AI-generated text

AI writing tends to follow distinct patterns, unlike human writing, which has more variation. Here’s what to look for to spot AI text in the wild:

  • A formal, robotic tone – AI writing often sounds robotic because it tends to repeat the same sentence structure and often lacks emotion or nuance.
  • Repetitive phrasing – Since AI generates words based on the patterns in its training data, it leans on familiar phrases, clichés, and even outdated language and information.
  • A lack of personal touch – AI-generated content can make generalizations and quickly synthesize information, but it lacks personal stories, emotions, or unique perspectives.
  • Predictable formatting – AI is great at structuring content—think title-case headings, neatly formatted bullet points, and polished phrasing.

Commonly used words in AI-generated content

Large language models (LLMs), such as GPT, generate text by predicting the most likely next word based on patterns learned from vast amounts of training data. Because of this predictive process, certain words and phrases tend to appear frequently in AI-generated content and can offer clues that the content was generated, rather than written by a person.
