AI Content Detection Made Simple
Detect AI-generated content with advanced algorithms and get actionable insights
Why Choose GPTDetector?
Multi-Model Detection
Our engine analyzes distinctive writing patterns across major AI systems including OpenAI, Claude, Gemini, and Perplexity to provide model-specific likelihood scores. See not just if text is AI-generated, but which AI style it most resembles.
Pattern Recognition
Advanced algorithms identify telltale AI writing patterns like repetitive structures, overly formal language, and characteristic phrase patterns that distinguish machine-generated content from human writing.
Confidence Scoring
Get detailed confidence scores showing the probability of AI generation, with separate scores for different AI models to help you understand exactly how your content is being evaluated.
Writing Style Analysis
Deep analysis of sentence structure, vocabulary choices, and writing flow to identify the subtle differences between human creativity and AI-generated patterns.
Instant Results
Get comprehensive detection results in seconds with our high-performance API that processes your text through multiple detection algorithms simultaneously.
User-Friendly Interface
Clean, intuitive design makes it easy to check your content quickly. Simply paste your text and get instant, easy-to-understand results without any technical knowledge required.
Frequently Asked Questions
Find answers to common questions about our AI detection service
Our detection system typically achieves 85-95% accuracy across different AI models. However, accuracy can vary based on text length (longer texts generally yield more accurate results), writing style, and the specific AI model used to generate the content. We recommend using our tool as one of several factors when evaluating content authenticity.
Our system can identify patterns from major AI systems including ChatGPT (GPT-5 and GPT-4), Claude, Google Gemini, Perplexity, and other large language models. Each model has distinctive writing patterns that our algorithms analyze to provide model-specific likelihood scores.
The scores represent the probability that content was generated by AI. A score of 0-30% suggests likely human-written content, 30-70% indicates mixed or uncertain origin, and 70-100% suggests high likelihood of AI generation. We also provide individual scores for different AI models to show which AI style the text most closely resembles.
Yes, false positives can occur. Formal academic writing, technical documentation, or highly structured content may sometimes trigger AI detection even when human-written. Similarly, non-native English speakers or content following strict style guides might be flagged. Always use the detection results as a guide rather than definitive proof.
For best results, we recommend at least 150-200 words. Shorter texts (under 100 words) may produce less reliable results as there are fewer patterns to analyze. The maximum text length depends on your plan, but longer texts generally provide more accurate detection.
When you submit text for analysis, it is processed through our API partners for detection. While we don't store your content on our servers, please note that API providers may process this data according to their own policies. For sensitive content, we recommend reviewing the privacy implications before submission.
Several factors can cause human content to be flagged: overly formal or generic writing style, heavy use of common phrases, repetitive sentence structures, or writing that closely follows templates. Professional writers who follow strict style guides or non-native speakers may also produce patterns that resemble AI-generated content.
Yes, it's possible. AI content that has been heavily edited by humans, mixed with human writing, or specifically prompted to avoid detection patterns may score lower on detection tests. Additionally, very short texts or highly creative/unconventional AI outputs might not trigger typical detection patterns.
Our detection algorithms are regularly updated to keep pace with new AI models and writing patterns. As AI technology evolves rapidly, we continuously refine our detection methods to maintain accuracy. Major updates typically occur monthly, with minor adjustments made as needed.
Detection tools are not infallible. If you believe the results are incorrect, consider: running the test again with a different text sample, checking if the content follows patterns that might trigger false positives, or using the results as one factor among several in your evaluation process. Remember, no detection tool can provide 100% certainty.
