Benchmark Methodology
Winston AI was evaluated on a curated dataset of 8 images, including models like Midjourney, Stable Diffusion, DALL-E 3, Flux, and others. The dataset also includes real photographs from verified sources to measure false positive rates.
All detectors are tested under identical conditions using the same images. We record each detector's classification (AI or Real) and confidence score, then compute three key metrics: Accuracy (percentage of correct predictions), False Positive Rate (real images incorrectly flagged as AI), and False Negative Rate (AI images missed by the detector).

What is Winston AI?
Winston AI is a comprehensive AI content detection platform that offers specialized image detection alongside text analysis. Developed by a Canadian company, Winston AI has gained recognition as one of the most popular AI detection tools on the market, serving educators, publishers, and content platforms.
Their AI image detector analyzes uploaded images using machine learning models trained to differentiate between human-created and AI-generated visuals, while also examining metadata including C2PA, IPTC, and EXIF data.
How Winston AI Image Detection Works
Machine Learning Analysis
- Trained classification models that identify AI generation patterns
- Multiple model versions with continuous improvement (v1, v2, v3)
- Pattern recognition across different AI generators
- Confidence scoring on a 0-100 scale
Metadata Forensics
- C2PA detection — identifies Content Credentials from Adobe, OpenAI, and others
- EXIF analysis — examines camera and software metadata
- IPTC inspection — checks content provenance information
- AI watermark detection — identifies invisible watermarks from major generators
Generator Recognition
Winston AI can detect images from:
- Midjourney
- DALL-E / ChatGPT
- Stable Diffusion
- Meta AI
- Adobe Firefly
- Other major AI generators
Key Features
Dual Detection Approach
Combines visual pattern analysis with metadata forensics for more reliable results than either method alone.
Developer API
- RESTful API with JSON responses
- Bearer token authentication
- URL-based image submission
- Detailed forensic results including watermark and metadata analysis
- 300 credits per image scan
Comprehensive Results
- AI probability score (0-100)
- Watermark detection (C2PA, SynthID, etc.)
- Full EXIF/IPTC metadata extraction
- Technical image properties
Multi-Format Support
- JPEG, PNG, WebP image formats
- Minimum resolution: 256x256 pixels
- URL-based image submission
Accuracy Claims
Winston AI claims to be "the only AI image detector with accuracy rate above 98%" — however, this claim has not been independently verified. Our benchmark provides unbiased third-party accuracy testing across multiple AI generators.
Pricing Model
Winston AI uses a credit-based pricing system:
- Free tier — 2,000 credits to get started
- Essential — $12/month for text and image detection
- Advanced — $19/month with API access
- Image detection cost — 300 credits per image
Use Cases
- Education — Verifying student work authenticity
- Publishing — Screening submitted images for AI generation
- Stock photography — Detecting AI-generated submissions
- Social media — Content authenticity verification
- Legal/compliance — Digital forensics and evidence verification
Limitations
- API requires publicly accessible image URLs (no direct file upload)
- 300 credits per image makes high-volume testing expensive
- Self-reported accuracy claims lack independent verification
- Newer AI generators may temporarily evade detection
- Heavy post-processing can reduce detection accuracy
