📝AI Text Detection
Our detection system is based on advanced AI technology that comprehensively analyzes 4 key dimensions of text, achieving over 90% accuracy. It performs exceptionally well for content generated by mainstream AI models like ChatGPT, GPT-4, and Claude. We recommend inputting at least 80 characters for more accurate results.
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 we've determined through extensive testing, ensuring accuracy without creating too much burden for users.
Our 4-dimension in-depth analysis includes: Statistical Distribution Analysis (detects if word choice matches AI's high-probability prediction patterns), Structural Logic Analysis (identifies overly neat logical connections and symmetrical structures), Tone Feature Analysis (discovers AI-specific neutrality and standardized expressions), Syntactic Burstiness Analysis (detects if sentence length distribution is too uniform). This multi-dimensional approach is more accurate and harder to bypass than single methods.
We support AI text detection in 14 languages, each specifically optimized: Chinese AI Text Detection (Simplified & Traditional), English AI Text Detection, Français Détection de Texte IA, Deutsch AI-Texterkennung, Español Detección de Texto IA, 日本語AIテキスト検出, Italiano Rilevamento Testo AI, Português Detecção de Texto IA, Русский Обнаружение ИИ-текста, हिंदी AI पाठ पता लगाना, বাংলা AI টেক্সট সনাক্তকরণ, العربية كشف النصوص بالذكاء الاصطناعي, Türkçe AI Metin Algılayıcı. We adopt 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 with billions of high-quality native language texts, our system can accurately capture the unique grammatical structures, semantic patterns, and expression habits of each language, ensuring language adaptability and accuracy of detection results reach industry-leading levels.
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, 文心一言 4.0, 通义千问 2.5, Kimi 2.0), Other AI models (Llama 4, Mistral Large 3). For mixed text (partially AI-generated + partially human-written), we can also provide reasonable judgments. Our system continuously updates to support the latest AI models.
Results are typically available in 3.5 seconds. Our system uses an optimized detection process with a circular progress bar showing real-time progress, keeping you informed of the current status.
Confidence level indicates the likelihood of text being 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 comprehensive 4-dimension analysis.

🖼️AI Image Detection
We support JPG, JPEG, and PNG format image detection. File size is limited to a maximum of 10MB, with images over 2MB automatically compressed to optimize upload speed.
Image detection typically takes 2-5 seconds. The specific time depends on image size and network conditions, with our optimized detection engine ensuring fast response.
Our AI image detection is based on our proprietary SAFE (Synthetic Artifact Feature Extraction) model, which uses discrete wavelet transform to identify unique high-frequency artifacts in AI-generated images, achieving 99%+ accuracy on standard test datasets. Our multi-modal analysis system combining CNN and Transformer architectures can accurately identify image characteristics from mainstream AI generation tools like Midjourney, DALL-E, and Stable Diffusion. We continuously update our model and algorithm fingerprint database to maintain leading performance as AI generation technology evolves.
We can detect images from almost all mainstream AI image generators, covering 5 major categories with 25+ tools and models: [1. Text-to-Image Models] Midjourney v7, DALL-E 4, Stable Diffusion 3, Google Imagen 3, Meta CM3leon; [2. Professional Design Platforms] Adobe Firefly 3, Canva AI, Microsoft Designer, Leonardo.ai, Playground AI; [3. Open Source Community Models] Flux, Stable Cascade, PixArt α, SDXL Lightning, OpenDALL-E; [4. Video Generation Tools] Sora, Runway Gen-3, Pika Labs, Kuaishou Kling, Vidu; [5. Chinese AI Tools] Baidu ERNIE-ViLG, Alibaba Wanxiang, ByteDance Doubao, iFlytek Spark, Tencent Hunyuan. Our system is continuously updated with algorithm fingerprint databases to support the latest AI generation techniques and model variants.
