What is an AI Content Detector?
An AI checker or detector helps you to verify the authenticity of your content. It analyzes your content and gives an AI detection score. Therefore, it lets you know whether the content is AI or human-written.
Our free AI Detector analyzes sentence structure, tone, length, vocabulary and patterns that most AI tools commonly use. In short, the score you get is highly accurate.
How to check AI using our AI detection tool?
Our AI text detector is very easy to use. Simply, follow these steps to check AI in your content:
Upload/Paste Text
The first step is to add your text to the box. You can copy and paste text directly or upload the text file. Our tool is compatible with taking text from doc, pdf, txt, or xml files.
Click on Check for AI
Select the AI detection mode from easy, normal, or hard according to your requirements. Then click on the “Check for AI” button to run our tool.
Let the Tool Analyze
The tool then analyzes each sentence individually, along with its tone, sentence length, sentence structure, vocabulary, and other characteristics. After detecting the content, our AI detector will give your content an AI detection score.
Review, Edit and Check AI Again
The AI text detector gives you an accurate score of AI detection. This score lets you know how much of your content is AI and human. If the score is high, then you can edit or humanize the content with the help of our AI humanizer as well. After editing the content, scan the content again until you get the desired results.
How do AI detectors differentiate human and AI-generated Text?
AI detectors usually detect various patterns that AI tools use frequently. These patterns include em dashes, buzzwords, empty metaphors, and throat-clearing intros (in the evolving world, in the fast-paced world), etc. Some other consistent patterns of AI-generated text are:
Perplexity
AI tools write content in a more predictable manner. Low perplexity means high chances of AI.
Burstiness
AI content includes consistent sentence length while humans write in variations.
Writing Style
The tone of AI-generated content is usually generic and over-polished.
Repetitive Patterns
AI-written content contains similar phrases, content structures, and transitions.
Linguistic and Statistical Features
AI Checkers analyze features like word frequency, grammar consistency, punctuation usage, and syntax.
Our AI content detector checks the list of parameters for deciding the AI score. This provides a reliable detection result.
