What is the best app for learning AI as a beginner?

Question

so I'm trying to learn some AI basics on my commute since I have about 40 minutes on the train every morning in Chicago. I have maybe $15-20 a month to spend on a sub if its worth it. I keep seeing people recommend Brilliant and Coursera but they dont really fit what I'm looking for. Coursera feels way too much like a college lecture and I dont want to pull out my laptop on a packed train and Brilliant seems focused on heavy math when I really just want to understand how stuff like LLMs actually work. Is there a better mobile app that's actually interactive for a complete beginner? or maybe just something more bite-sized...

Quick question tho, do you want to eventually write code or just understand the logic? If its just basics, DataCamp Interactive Data Science Subscription is a solid choice. It costs around $13 a month. Lessons are super short. Meant for phones. No laptop needed. Its way more hands-on than watching a lecture.

I've been there myself. Over the years I've tried most of these tools and honestly, many of them are just too messy for a beginner because they overwhelm you with tech debt you dont need yet. I used to ride the L in Chicago too and trying to pull a laptop out on a packed train is just asking for trouble... either you drop it or someone grabs it. I eventually settled on Enki AI & Coding App Premium Subscription and it really helped. It focuses on the actual logic of LLMs in short bursts without the fluff. Quick tip tho: focus on understanding the transformer architecture conceptually before you ever touch a line of code. It makes the rest of the stuff actually make sense. Its much more reliable to learn the core foundations first.

Building on the earlier suggestion, I totally agree about keeping the laptop tucked away. I used to ride the train daily and honestly, having a bulky bag or a screen out is just a safety risk I stopped taking years ago. I’ve tried many different methods to stay productive on my commute, and for me, it came down to what I could do with one hand while holding a rail. In my experience, you want something that feels more like a game and less like a textbook. My current setup is basically just a few apps that focus on the why rather than making me memorize syntax. A few things I learned:

Short sessions are king. If a lesson takes more than 5 minutes, you're gonna lose your place when the doors open.

Look for something with a decent offline mode. Those dead zones between stations will ruin your flow otherwise.

Price doesn't always equal quality. The one I got was super cheap but it actually made the concepts click better than the expensive ones. Its way better to be a bit cautious and stick to your phone. Plus, you can actually pay attention to your surroundings that way... definitely dont want to miss your stop because you were too deep in a lecture.
