Frequently Asked Questions

Our AI Detector achieves industry-leading accuracy rates of 95%+ in identifying AI-generated content. We use advanced machine learning models trained on millions of text samples from both human writers and AI models like GPT-5, Claude, and Gemini. The detector analyzes multiple factors including writing patterns, perplexity, burstiness, and linguistic markers to provide reliable results.
Our AI Detector can identify content generated by all major AI writing models including ChatGPT (GPT-3.5, GPT-4, GPT-4 Turb, GPT-5), Claude (all versions), Google Gemini, Llama, Mistral, and other popular language models. We continuously update our detection algorithms to stay current with new AI models and their writing patterns.
Yes, our detector can analyze text that combines human writing with AI-generated sections. It provides sentence-level analysis showing which specific parts are likely AI-generated versus human-written. This granular detection helps identify content where AI has been used to enhance or supplement human writing.
The confidence score represents the probability (0-100%) that the analyzed text is AI-generated. Scores above 80% indicate high confidence of AI content, 50-80% suggests possible AI involvement, and below 30% indicates likely human writing. The score is calculated by analyzing multiple linguistic features and comparing them against known AI writing patterns.
For optimal accuracy, we recommend analyzing at least 50-100 words. Shorter texts may not provide enough data for reliable detection. The detector works best with complete sentences and paragraphs rather than fragments or individual sentences. Longer texts (250+ words) generally yield the most accurate results.
Yes, our AI Detector is specifically optimized for academic content including essays, research papers, dissertations, and assignments. It's designed to handle formal academic writing styles and can identify AI-generated academic content with high accuracy. Many educators and institutions use our detector to verify student work authenticity.
Detection limits depend on your subscription plan. Free users have access to a limited number of daily detections. Premium plans offer higher detection limits with larger text analysis capabilities. Check our pricing page for specific limits based on your plan tier.
Like all AI detection tools, ours can occasionally produce false positives (flagging human text as AI) or false negatives (missing AI content), though our 95%+ accuracy rate minimizes this. Factors like writing style, topic complexity, and text length affect accuracy. We recommend using detection results as one data point among several when evaluating content authenticity.
We take privacy seriously. Submitted text is processed in real-time for detection analysis and is not permanently stored or used for training purposes. Your content remains confidential and is automatically discarded after analysis. We do not share, sell, or retain any text you submit for detection.
Yes, our AI Detector is suitable for both personal and professional use. Businesses, publishers, educators, content agencies, and hiring managers use our detector to verify content authenticity. Premium plans offer higher limits and features designed for professional users who need to analyze large volumes of text regularly.
Our AI Detector offers several advantages: industry-leading 95%+ accuracy, sentence-level analysis showing exactly which parts are AI-generated, support for all major AI models including the latest GPT-5 and Claude versions, and regular updates to stay current with evolving AI writing patterns. We also provide detailed confidence scores and comprehensive reporting.
