1 ChatGPT Checker
A Pioneer - and Best in Coverage -in AI Detection

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

Our AI Checker has 98% Accuracy

Trained on blog posts, 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.

3 AI Text Detector
Simplified Scoring

When you run your text through the 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).

4 AI Detector
In-Depth Analysis Down to the Sentence Level

We don't just give you an overall score — we actually break this down sentence-by-sentence and tell you exactly where your content is being flagged. This way you know exactly where to focus your revision efforts.

And here’s what makes Content at Scale's AI Detector best-in-class: flagged content will be graded green, yellow, orange, or red – complete with suggestions on how to edit it to get a higher human probability score. You can even use our paraphrasing tool to fix it!
