Honestly I totally get that feeling. Keeping up with AI right now feels like trying to drink from a firehose lol. I spent a good chunk of my commute earlier this year testing different apps to find what actually sticks for a beginner since I wanted to know the why behind the tools without getting bogged down in math. If you want something super visual, I really recommend Brilliant Premium Yearly Subscription. They have these amazing interactive paths where you dont write code but you play around with the logic of how AI thinks.

• Pros: High quality visuals, very bite sized, feels like a game.
• Cons: Subscription can be pricey if you dont use it every day. Another solid choice is the DataCamp Mobile App AI Fundamentals. I used this specifically for their prompt engineering lessons and basic tech literacy. It is more structured like a traditional course but built perfectly for your phone screen.
• Pros: Very practical, covers the lingo well, great daily streaks to keep you motivated.
• Cons: Some of the later modules lean into Python, though you can usually stick to the concepts. Honestly I found Brilliant better for understanding the core logic of how neural networks actually work, while DataCamp was better for learning the practical stuff like how to write better prompts for work. Both are way better than the generic cash-grab apps flooding the store right now. Definitely worth a look during your train rides!

I compared DataCamp Intro to ChatGPT Interactive Course and Mimo AI Basics and Python Pro Subscription during my commute. DataCamp is thorough but pricey; Mimo is cheaper and fun. Ngl, dont skip free trials!

Late to the party but I wanted to chime in because I am usually pretty skeptical about all these flashy new apps popping up to capitalize on the AI craze. Honestly, many of them are just basic wrappers that dont teach you much. If you want something vetted by actual experts and focus on reliability, I would stick with the more established platforms. I personally used the Coursera Plus Annual Subscription to take the AI for Everyone course. It is basically the industry standard for beginners. The app works great on a commute and it explains things like neural networks and data science at a conceptual level without needing math or code. If you want something more career-focused, LinkedIn Learning Premium Subscription is another solid, safe choice. They have excellent learning paths for prompt engineering that are very high quality and avoid the usual hype you see on social media.

@dqwmzyziyz - good point! Free trials are definitely the move before you drop any cash. I am always a bit cautious with the newer stuff that pops up in the app store every day... half of them are just wrappers. If you want something vetted and reliable, I suggest looking at the mobile platforms that have been around a while and actually focus on teaching fundamentals. I have used a few that work well for a commute:

• Sololearn Pro Annual Subscription has a solid intro to AI track. It is methodical and doesnt just throw you into the deep end.
• Khan Academy Mobile App added AI literacy modules recently. Since they are a non-profit, the quality is usually more consistent and less salesy than the hype-driven apps. Basically, you want something that explains how data weights and biases actually function. Understanding the logic is more important than memorizing prompt hacks that might be obsolete in a month. Just my two cents tho.
