There is no limit to how many times you can use the AI Detector. You can use it as many times as you'd like, however, text highlighting is only available to signed-in users.
Our AI writing detector is the most accurate in the industry, with an accuracy rate of 99.8%. Although we are constantly improving our algorithms, please note that no method of detection is 100% accurate. False positives are inevitable, but we are working hard to reduce them as much as possible.
Our humanizer is trained on over 300,000 human-written articles. When you use the humanizer, it uses its knowledge of grammar, syntax, and structure to generate content that is indistinguishable from human-written content. This way, your output will be undetectable by any AI generator checker.
What is an AI Detector?
An AI detector is a tool designed to identify content that has been generated by artificial intelligence systems like ChatGPT, GPT-4, Claude, or other language models. These detectors analyze text patterns, writing style, predictability, and other characteristics to determine whether content was written by a human or an AI.
Our AI detector uses advanced algorithms trained on vast datasets of both human-written and AI-generated content to deliver accurate results. It can help you identify content sourced from various AI writing tools and determine if text has been fully AI-generated, partially edited by humans, or entirely human-written.
Why use an AI Detector?
There are several important reasons to use an AI detector in today's digital landscape:
- Academic Integrity: Educational institutions increasingly use AI detection tools to ensure students submit original work rather than AI-generated content.
- Content Authenticity: Publishers, bloggers, and content creators may want to verify that their work appears natural and human-written.
- Quality Assurance: Companies using AI tools for content creation can check whether the output meets quality standards and appears authentic.
Our free AI detector provides an easy way to check your content before submission to ensure it passes other AI content detectors used by schools, employers, or publishers.
How does our AI Detector work?
Our AI detector works by analyzing various linguistic patterns and characteristics that differentiate human-written content from AI-generated text:
- Statistical Analysis: We examine word choice, sentence structure, and text predictability patterns that often differ between human and AI writers.
- Stylistic Markers: AI tends to use certain phrases, transitions, and structural elements differently than human writers.
- Complexity Assessment: Our tool evaluates the complexity and variability of the content, as AI-generated text often shows different patterns than human writing.
While our detector is highly accurate at 99.8%, it's important to understand that AI detection technology is constantly evolving alongside AI writing technology. No detection system is perfect, but our advanced algorithms provide one of the most reliable assessments available.
What about the AI Humanizer?
Our AI Humanizer is a complementary tool designed to help you make AI-generated content appear more natural and human-written. It rewords and restructures AI text to help it bypass detection while maintaining the original meaning. This can be particularly useful for:
- Students who use AI as a learning aid but need to submit original-seeming work
- Content creators who use AI to draft content but want it to sound authentic
- Professionals who need AI-generated content to pass quality checks
