Humanizer

A skill that rewrites AI-generated text so it reads more naturally, without changing what it says.

Fast-rising

What it does

Humanizer is a skill, an instruction pack, for AI assistants like Claude, Codex and others. It looks for common signs of AI writing, based on a guide Wikipedia editors use, and rewrites them. Examples include phrases like "It's not just X, it's Y" and dramatic one-line endings.

It checks for 26 patterns, shows its first rewrite and a short critique, then gives a final version. It aims to keep every fact, name and number unchanged. You can also give it a sample of your own writing so the result sounds more like you.

Its makers say it edits for human readers and that getting past AI detectors is not a goal.

Who it's for

Writers, marketers and anyone who uses AI to draft text and wants it to sound less machine-made.

Can I use it without coding?

With some setup. In the Claude app you can upload it as a skill in Settings. Other tools install it with a short command. New to this? Start here.
