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, students, 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.
More clarity, less confusion with Verla's AI Detector
Paraphrasing and grammar checking tools are ethical uses of AI writing technology. They help millions of non-native English speakers and writers refine their text and express their ideas fluently.
But most AI detectors can't tell the difference between text that's been created with generative AI tools — such as ChatGPT, GPT-4, Gemini, Llama, Claude and others — and text that's been refined using assistive tools. This leads to false positives and unfair results.
So we built a more reliable AI detector.

The Technology Behind Verla's AI Detector
Verla's 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.
For every text, you'll get a probability score that suggests its likely source. As with any AI detector, this score is not a guarantee, but it is a useful signal when authorship matters.
