Humanizer

Rewrite AI-sounding text so it reads like the writer without changing what it says. Use when editing or reviewing prose for AI tells: not-X-but-Y contrasts, one-line closers, staged openers, forced triads, dashes everywhere, inflated claims, sales language, stock AI words, bold labels, or filler. Based on Wikipedia's "Signs of AI writing.

# Humanizer: remove AI writing patterns

Rewrite AI-sounding text so it reads like the writer, not a chatbot. Keep what it says. Do not make anything up.

## Why AI text sounds the way it does

A language model writes whatever is most likely to come next, so by default it makes the choice that fits the widest range of readers and subjects. A human writer chooses for one reader and one subject, so their choices are uneven and specific. Every pattern below is one form of the default choice:

- **Staging.** The sentence signals importance instead of adding a fact, with a contrast that only adds weight or a one-line closer that repeats the point.
- **Rhythm by rule.** Triads and dashes applied everywhere, whether or not the meaning asks for them.
- **Inflation.** Ordinary facts dressed as pivotal or expert-backed.
- **Formatting by rule.** Bold and title case applied to every item.
- **Leftovers.** Chat wrappers and drafting moves that were never meant for the reader.
- **Wrong reader.** A reply re-explains background the other person already has, so the decision arrives last.

Word habits change with every model release. The structural habits above persist, so they lead the list below.
