> I’m looking for something interactive with bite-sized lessons covering machine learning and LLMs.

So basically, neural nets rely on specific mathematical weights to process data, which is the actual foundation for any AI work. Because of that, I would suggest DataCamp: Learn Data Science for ur commute. It’s a technical but bite-sized investment that covers real ML architecture rather than just surface-level fluff... definitely worth the cost tbh.

In my experience, I'd highkey suggest these two for ur commute:

- Brilliant.org Premium Subscription is the best for interactive machine learning—it's realy worth the price for those bite-sized lessons.
- Enki: Learn AI and Coding if you want something budget-friendly that covers LLM basics well...

Both work great offline, honestly no complaints, gl!

I totally agree that the technical foundation is key, but honestly, I'm always kinda paranoid about downloading random 'AI tutor' apps that just popped up. There's so much unreliable stuff on the App Store that might just be scraping old data or giving you hallucinated info. If you're on a budget but want something super reliable and safe, I’d look at these: * Sololearn: Learn to Code — Their AI intro is free-ish and the community stuff keeps the lessons pretty accurate.
* Coursera — You can actually 'audit' most machine learning courses for free on their app. It’s better for your commute because the info is vetted by actual pros, so it’s way more legit than some random $10/month wrapper app. Basically, it's safer to stick with the big names so you aren't wasting time on unreliable content, you know?

TL;DR: Mimo: Learn to Code and AI for quick gamified streaks, Coursera Mobile App for university-level depth. Just saw this and honestly spent way too much time testing these lately. Mimo is basically the Duolingo of coding and AI. Its super chill for a commute because the lessons are tiny, though it doesnt go deep into the heavy math. If you want something more rigorous, the Coursera app lets you audit courses from big universities. You can download lessons for when the signal drops in the subway which is a lifesaver. Quick tip: dont try to learn everything at once. Pick one path and stick to it for at least a week to see if the teaching style clicks with you. Let me know if you need more help picking a specific course!

Same setup here, love it

Can confirm

Regarding what #6 said about "Same setup here, love it"

• I'm right there with you, having a set routine makes the commute actually productive. Ive been at this for over a year and the progress is real. Since the others covered the main ones, I'd suggest looking at Khan Academy App for the fundamental math and logic. Its free and doesn't feel like it's trying to sell you something every five minutes. Another solid one is LinkedIn Learning App if you want to see how AI fits into actual workflows. Pro tip for the long term: check your local library for free LinkedIn Learning access—it saves so much money. Also, download everything for offline use because train wifi is usually trash lol.
