Most people use AI every day. Almost no one understands how it actually works. Axon teaches you AI from the ground up — the math, the intuition, and the systems behind modern models. Learn linear algebra, probability, calculus, gradients, backpropagation, transformers, and more through short, interactive lessons designed for real understanding, not memorization. INTERACT WITH THE MATH, DON’T JUST READ IT Every concept is hands-on. Drag a gradient and watch the loss change. Adjust a weight and see predictions shift in real time. Step through a neural network layer by layer. You learn by doing — in just five minutes a day. BUILT FOR MACHINE LEARNING. NOTHING ELSE. No generic computer science filler. No hand-waving past the difficult parts. Axon focuses on the ideas that actually matter in machine learning — and explains them clearly, without oversimplifying. WHAT YOU’LL LEARN Math Foundations Vectors, matrices, derivatives, probability, softmax, and the core math behind ML Core Machine Learning Regression, gradient descent, loss functions, overfitting, evaluation, and optimization Neural Networks Perceptrons, backpropagation, CNNs, activations, and optimizers Transformers & LLMs Attention, embeddings, tokenization, prompting, and transformer architecture Frontier AI RAG, AI agents, fine-tuning, reinforcement learning, and modern workflows Practical Skills Classical algorithms, MLOps, and hands-on capstone projects MEET TENSOR Your guide is an undertrained model that somehow became sentient. Tensor is fluent in math, slightly confused by humans, and always focused on helping you learn. STAY CONSISTENT Daily streaks, XP, and global leaderboards turn consistency into momentum. Short lessons make it easy to come back tomorrow. AXON PRO Unlock unlimited lessons, advanced exercises, new outfits, unlimited review, and early access to new content. Available monthly or annually with a free trial. Terms of Service: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict
The clearest difference is update cadence: Axon at every 5 days against CS Pro Note's monthly. CS Pro Note's advantage is iOS requirement (13.0 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.
