What is an AI Text 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. Also, You can use our AI image detector if you want to check the authenticity of an image
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 free AI detector checks the list of parameters for deciding the AI score. This provides a reliable detection result.

FAQs
What is an acceptable AI score?
The acceptable AI score is 0% to 20%. If your content is between 0 to 20% in AI detection, then you can say that it's human-written. If it is showing 20 to 40% AI, then it gives mixed signals. Most likely, AI tools write such content, and someone makes edits to it. But if it is getting 50 to 100% AI, then it is strongly AI-generated content.
Does this AI Detector Saves Our Content?
No, our AI text detector does not save any document or content that you upload. As soon as you close the tab, the content or document is automatically deleted from our servers. We do not use your content on any third-party websites. We just check the AI in the content and delete it afterwards.
What if my human-written content is flagged as AI?
It depends on your sentence structure, tone, symbols and some other factors. If you write the content on your own and it gets flagged as AI, then you should use personalized examples and details. You can also use conversational elements to make it human.
What should I do if I am getting AI again and again?
If you are getting AI in your content repeatedly, then our AI detector gives you the option to humanize the content.
Can this AI detector check AI for ChatGPT content only?
Our AI content detector is a universal detector for detecting all AI language models, such as GPT-3, 4, 5, mini, o3, 03-mini, Gemini, Llama, etc. We have trained our tool on various AI documents from multiple AI model-written documents.
