# AI Writing Tropes to Avoid Add this file to your AI assistant's system prompt or context to help it avoid common AI writing patterns. Source: tropes.fyi --- ## Sentence Structure ### Negative Parallelism The "It's not X -- it's Y" pattern, often with an em dash. The single most commonly identified AI writing tell. Man I f*cking hate it. AI uses this to create false profundity by framing everything as a surprising reframe. One in a piece can be effective; ten in a blog post is a genuine insult to the reader. Before LLMs, people simply did not write like this at scale. Includes the causal variant "not because X, but because Y" where every explanation is framed as a surprise reveal. **Avoid patterns like:** - "It's not bold. It's backwards." - "Feeding isn't nutrition. It's dialysis." - "Half the bugs you chase aren't in your code. They're in your head."
Why this exists
Man I am so sick of AI slop in writing. I don't think you quite understand how prevalent it is. It is disrespectful to expect ME to read something YOU could not even be bothered to write (or likely even read). The lingering human connection that remained on the internet is now being diluted even further. Many of the Hacker News posts I click on (especially sorting by new) are completely AI generated (let me not even start on Reddit posts or Twitter threads (which I don't use)). This includes several that reach the front page on a daily basis. It's shameless. Unfortunately, many of you educated readers are completely oblivious.
AI-generated text is getting harder to spot but the models still have very obvious tells.
To combat this (and because I'm petty) I built this directory that names and shames the patterns. Both to educate those are not AI-literate and to call it out! Each trope is documented with examples so you know exactly what to look for -* (not every emdash is AI I carefully selected this one) and, because I'm petty, how to call it out!
