Humanizers by model
ChatGPT doesn't write like Claude, and detectors know it. These guides cover the telltale patterns of each major AI model and how to rewrite them into text that sounds like a person.
Use cases
An email, an essay and a product description fail for different reasons when AI writes them. Pick your situation for specific guidance on making the text genuinely yours.
Blog
How detectors actually work, why they sometimes flag human writing, and what genuinely makes text read like a person wrote it — explained without the hype.
Glossary
The vocabulary of AI writing and AI detection, defined in plain English — so when a detector report says "low perplexity", you know exactly what it means.
