What is I Spy AI?
I Spy AI is an innovative tool designed to detect whether an image was generated by artificial intelligence. Unlike other detectors that rely on machine learning models or black-box classifiers, I Spy AI uses pure OpenCV for analysis, ensuring no data mining occurs during the process. This approach makes it accessible and straightforward for anyone to use. The detection system runs on a FastAPI backend, with a Next.js frontend handling authentication, billing via Dodo Payments, and image proxying to maintain low latency. Inspired by the subreddit r/isthisai, where users often debate whether images are real or AI-generated, I Spy AI aims to provide clarity without requiring any specialized software or enterprise-level access. The tool is particularly useful for those working with large language model agents like Claude Desktop or Cursor, as it can be integrated via a simple API call.
What is I Spy AI used for?
People use I Spy AI to check whether an image is AI-generated, using classical computer vision, and can call it via API from agent tools.

Pros and cons
Pros
• Detects whether an image was AI-generated using classical computer vision (OpenCV) • Avoids black-box ML classifiers, so the analysis approach is transparent • No data mining during analysis — a privacy-focused design • Can be integrated via a simple API call into agent tools like Claude Desktop or Cursor • Straightforward to use without specialized or enterprise software
Cons
• Classical CV detection can be less accurate than trained ML models on newer generators • Detection is inherently imperfect as image-generation quality improves • Free-versus-paid usage limits are not clearly published • Best suited to spot-checks rather than legal-grade proof of origin
Questions about I Spy AI
What is I Spy AI?
I Spy AI is a tool that detects whether an image was generated by AI. It analyzes images with classical computer vision (OpenCV) instead of a machine-learning black-box classifier.
How is I Spy AI different from other detectors?
Most detectors rely on trained ML models. I Spy AI uses pure OpenCV analysis and does no data mining during the process, making it a more transparent, privacy-focused option.
Can I use I Spy AI with AI agents?
Yes. It runs on a FastAPI backend and can be integrated through a simple API call, which makes it usable from agent tools like Claude Desktop or Cursor.
Is I Spy AI accurate?
It provides a fast, transparent signal about whether an image looks AI-generated, but no detector is perfect — classical methods can struggle as generators improve, so treat results as an indicator rather than proof.
