Phrasing Patterns

  • Lots of complex clauses, sentences are monotonous and do not vary much in length or style, rather than human text, which uses a variety of different phrasing patterns
  • Human writing uses a mix of simple and complex sentences, and even expert-level writers will sometimes use grammatical patterns that aren’t “by the book perfect” or mess up a tense or preposition here and there.
  • AI uses em dashes — often as a way to add explanatory clauses or dramatic pauses
  • AI does not often use semicolons, parentheses

Spelling and Grammar

  • AI uses American English spelling
  • It is very rare for AI to make spelling errors, unless it is directly prompted to do so
  • Rarely uses contractions like "we've"
  • "Perfect" grammar: avoids fragment, run-ons, starting sentences with "And" or "But"
  • AI uses Oxford commas

Organization and Structure

  • AI writing generally likes to use very organized paragraphs that are all about the same length and list-like structures. Sometimes bullet point lists show up in the middle of the essay which rarely happens in formal human writing. AI-generated essays usually have a very neat introduction and conclusion, and the conclusion is often very long, starts with “Overall,” or “In Conclusion”, or “In summary”, and repeats most of what was already written.
  • Human writing contains a variety of structures and organizations and paragraph length is more varied. Conclusions tend to be shorter.

Purpose and Intent

  • Because AI is trained to be assistive and people-pleasing, AI tends to write essays that could fit a wide variety of possible prompts and instructions, to avoid being irrelevant or off-topic. As a result, the writing is usually very vague and full of generalities.
  • Human writing is generally more aligned to the particular assignment or prompt that is given to them.

Tone

  • AI generated text writes in an extremely formal tone unless it instructed not to. It also tends to be overly positive, and avoid criticizing particular viewpoints or opinions.
  • AI often exhibits earnestness, specifically pointing out evidence that it is being helpful.

Creativity and Originality

  • Because AI merely replicates patterns in its training set, AI is unable to produce any creative or original thoughts. It simply parrots thoughts that it has already been exposed to during its training process.
  • AI also reflects the political views and biases of its creators.
  • On the other hand, on many topics, the AI aggregates so many sources of text and information that it has no clear perspective or point of view: it aggregates so many perspectives that it has none itself.

Specificity

  • AI does not create specific details when writing creatively, and tries extremely hard to avoid proper nouns
  • When forced to say a proper noun, AI will default to the most generic, common proper noun possible
  • “AI Names” are a thing: 60-70% of names in AI-generated articles from ChatGPT and Claude are either “Emily” or “Sarah”

Reflection and Metacognition

  • AI is very bad at reflecting and relating the writing to personal experiences… because it has no personal experiences that it can relate to!
  • AI can also not reflect upon its own writing process because it simply is a machine: there is no equivalent “writing process” that it follows
  • Human writing (can) show the unique voice and personal experience of its author.

Repetition

  • AI often repeats itself, especially in the conclusions
  • AI will often repeat the prompt back to the user, to make sure it is following instructions

Abrupt shifts in style and tone

  • In cases where human writing is mixed with AI writing, there are often abrupt shifts in the style and the tone where the human text becomes AI or vice versa.
