The AI Detector

ChatGPT and AI Text Tools are Here: Time to Check Your Content

We use natural language processing and a trained model using artificial intelligence to detect patterns, forecast probable word choices, as well as understand sentence structure and other characteristics that lead to a higher AI probability within a typical AI Checker.

NEW: All new grading for the AI Detector, modeled off more GPT-4, Bard, and Claude content.
Our AI Checker now achieves higher levels of accuracy. We have simplified the scoring to give you an overall probability of it being written by a human. A score of 1% means it is 99% likely that it was created by AI. Also new is our human-level paraphrasing tool.

Quite simply, we were one of the two first AI detectors that existed. We existed BEFORE ChatGPT and have continued to improve since then. Why were we early? Because Content at Scale was the first long form AI SEO writer on the market and we had to overcome the "can people tell it's AI?" objection.

Our AI Checker is used by students, professors, content marketers, marketing agencies, freelancers, and anyone wanting to make sure their output does not read robotically.

You can use our AI Content Detector to check for any AI model.

Currently, the AI Detector is just for the English language.
