Frequently Asked Questions
How accurate are the detection results?
Our detection system is based on advanced AI technology, comprehensively analyzing 4 key dimensions of text, with an accuracy rate of over 90%. It is particularly effective for content generated by mainstream AIs like ChatGPT, Claude, and Gemini. We recommend entering 80+ characters for more accurate results.
Why is there a minimum of 80 characters required?
AI text detection requires sufficient context for accurate analysis. Too few characters lead to insufficient samples, affecting the reliability of 4-dimension analysis. 80 characters is the optimal balance point we determined through extensive testing, ensuring accuracy without burdening users.
What does the 4-dimension analysis check specifically?
Our 4-dimension deep analysis includes:
• 📊 Statistical Distribution Analysis: Detects if word choices match AI's high-probability prediction patterns • 🏗️ Structural Logic Analysis: Identifies overly neat logical connections and symmetrical structures • 🎯 Tone Characteristic Analysis: Discovers AI-specific neutrality and standardized expressions • 📝 Sentence Variation Analysis: Detects if sentence length distribution is too uniform (AI tends to be uniform, humans have random fluctuations)
This multi-dimensional analysis is more accurate and harder to bypass than single methods.
Which languages are supported for AI text detection?
We support AI text detection in 14 languages, each specifically optimized:
Asian Languages: Chinese AI Text Detection (Simplified/Traditional), Japanese AI Text Detection European Languages: English, French, German, Spanish, Italian, Portuguese, Russian Other Languages: Hindi, Bengali, Arabic, Turkish
We use a multi-language specialized model architecture, where each language uses a large language model specifically fine-tuned for that language's characteristics. By building training datasets containing billions of high-quality native texts, our system can accurately capture the unique grammatical structures, semantic patterns, and expression habits of each language, ensuring industry-leading language adaptability and accuracy.
Which AI-generated content can be detected?
We can effectively identify content generated by the following mainstream AI models:
OpenAI Series: GPT-5.2, GPT-4 Turbo, GPT-4, ChatGPT, GPT-3.5 Anthropic Series: Claude 4.5 Sonnet, Claude 4 Opus, Claude 3.5 Sonnet, Claude 3 Opus Google Series: Gemini 3 Pro, Gemini 2 Pro, Bard xAI Series: Grok 4.1, Grok 2 Chinese AI Series: DeepSeek V3.2, DeepSeek V3, Wenxin Yiyan 4.0, Tongyi Qianwen 2.5, Kimi 2.0 Other AI Models: Llama 4, Mistral Large 3
Reasonable judgments can also be given for mixed text (partially AI-generated + partially human-written). Our system will continue to update to support the latest AI models.
How long does a detection take?
Usually 3.5 seconds to get results. Our system uses an optimized detection process with a circular progress bar showing real-time progress, keeping you clearly informed of the current status.
How is it determined that text is AI-generated?
Confidence level indicates the likelihood that text is AI-generated:
• ≥70% (Red): Very likely AI generated • 40-69% (Yellow): Possibly AI generated • <40% (Green): Very likely human written
This score is calculated based on a comprehensive 4-dimension analysis.
Will my text be saved?
Absolutely not. The entire detection process is completely anonymous. Your text will not be saved, recorded, or used for any other purpose. It is deleted immediately after detection, ensuring privacy and security.
Can it be used on mobile?
Absolutely! Visit our website and click "AI Text Detection" in the navigation menu to use it smoothly on your phone. The mobile interface is specifically optimized for simple and convenient operation.
Is there a batch detection feature?
Currently we focus on the accuracy of single detections to ensure every result is reliable. Batch detection is in planning, so stay tuned.
