Trusted AI Detector & AI Checker
Paste your text below to check if it was written by AI. Our AI Detector is trained on GPT-4, GPT-5, Gemini, Claude, and Llama and trusted by millions of users.
What is an AI Detector?
An AI detector is a tool designed to analyze written content and identify whether it was created by a human or generated by artificial intelligence. It can detect content from major models, including ChatGPT, Gemini, Claude, and Llama, and accurately distinguish between fully AI-generated text and content that has been refined using assistive writing tools.
AI detectors are widely used by educators, businesses, publishers, and content creators to verify originality, protect content quality, and promote transparency. Supporting all major languages, our AI Checker provides detailed feedback, helping users quickly verify the authenticity of content in seconds.

Detailed analysis
Know exactly which part of the text appears to be AI-generated with percentage breakdowns.
High accuracy
Advanced models for highly accurate results using pattern recognition and machine learning.
Fast
Receive your AI detection report within seconds of submitting your text.
Multilingual support
Supports all languages with accurate detection across different writing styles.
The Technology Behind our AI Detector
Our AI Detector analyzes patterns to estimate the likelihood that a text is human written or AI generated. Instead of flagging individual words, our detector notices structural signals like repetition, generic language, and lack of variation in tone.
Our detector works because it is trained on large sets of human- and AI-written texts generated using models like GPT-4, GPT-5, Claude, Gemini, Llama, and other modern large language models. It uses metrics such as perplexity (how predictable the text is) and burstiness (how much sentence length varies) to identify writing patterns typical of machines.
When the result is unclear, our model tends to classify texts as human written, which reduces false positives. For the most accurate results, analyze your entire text at once, and make sure it meets the length requirement. Always interpret results in light of your own knowledge.
AI Detector FAQs
How accurate is our AI Detector?
Our AI Detector uses advanced LLM-based linguistic pattern analysis to identify AI-generated text, including outputs from GPT-4, GPT-5, Claude, and Gemini. Our models are continuously trained on large datasets to stay current with evolving AI writing systems, ensuring high accuracy and reliability across all content types.
How is our AI Detector different from other AI detectors?
Our AI Detector distinguishes how AI was used to create your content. Our analysis will tell you if each section of writing was:
- AI-generated
- AI-generated & AI-refined
- Human-written & AI-refined
- Human-written
This way, you don't just know if AI may have been used to generate the content. You can also understand how assistive tools may have been used in the writing process.
Who benefits from our AI Detector?
Our AI Detector is a valuable tool for educators, students, teachers, writers, freelancers, copywriters, and anyone else who needs to identify AI-generated text.
Can our AI Detector detect all types of AI-generated content?
Our AI Detector can only detect text and not images, video, or other rich media content.
Does our AI Checker support multiple languages?
Our AI Detector accurately analyzes text in all languages, providing reliable detection results regardless of the language used.
