Introduction to Our 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.

What Sets Our Best-in-class AI Content Detector Apart?

1 A Pioneer — and Best in Coverage — in AI Detection

Our AI Detector was one of the first ever and goes deeper than a generic free AI content detector.

A free AI checker is usually hit or miss. Meanwhile, Content at Scale's AI Detector can detect content generated by ChatGPT, GPT4, GPT3, Bard, Claude, and other LLMs.

2 98% Accurate AI Checker

Trained on online blogs, wikipedia, essays, and more. Our AI checker looks for patterns that indicate AI-written text (such as repetitive words, lack of natural flow, and generic tone), forecasts probable word choices, and analyzes sentence structure and other characteristics for 98% accuracy.

AI Content Detector
3 Simplified Scoring

When you run your text through our AI detector, you will get an overall probability that determines whether your content is likely to be written by human or machine (or you just write like one).
