When you upload a photo to Aedion's skin scan feature, you're not just sending it to a chatbot. Behind the scenes, a specialized AI model called a Convolutional Neural Network (CNN) analyzes your image in a way that's fundamentally different from how general-purpose AI like ChatGPT works.

What Is a CNN?

A Convolutional Neural Network is a type of AI designed specifically for image analysis. While language models process text, CNNs process visual data — looking at pixels, edges, colors, and shapes. They learn to recognize patterns by training on thousands of labeled images.

Think of how a dermatologist examines a mole: they look at border regularity, color uniformity, diameter, and whether it has changed. Our CNN does something similar, evaluating visual features including color distribution, shape geometry, texture patterns, and structural symmetry.

The Analysis Process

When your image arrives, our system processes it through several stages. First, the image is preprocessed — normalized for lighting, cropped to the relevant area, and standardized in size. Then the CNN passes it through multiple layers, each detecting increasingly complex features: edges in the early layers, textures in the middle, and complete patterns in the deeper layers.

The output is a pattern assessment — not a diagnosis. Aedion identifies visual characteristics and categorizes them by how closely they match known patterns. When something looks like it could benefit from professional evaluation, Aedion tells you so.

Why Not Just Use ChatGPT?

General-purpose language models like ChatGPT can look at images and describe what they see. But they aren't purpose-built for medical pattern recognition. Aedion's CNN was trained specifically on skin image datasets, meaning it has learned patterns that a general model simply hasn't been optimized for.

The difference is like asking a well-read journalist versus a trained radiologist to examine an X-ray. Both are intelligent, but only one has the specialized training for the task.

Important Limitations

Our AI is a wellness tool, not a medical device. It does not diagnose conditions, and it is not a substitute for professional medical evaluation. Photo quality, lighting, and camera distance all affect results. We always recommend consulting a healthcare professional for any health concern, especially if Aedion identifies a pattern worth monitoring.

We are continuously improving our model's accuracy and expanding the range of patterns it can detect. Transparency about what our AI can and cannot do is central to how we build trust with our users.
