Same problem exists for all educational apps. Duolingo users have the goal of learning a language, but also they only want to use Duolingo for a few minutes a day, but also they want to feel like they're making progress. Duolingo's goal is to keep you using Duolingo, and if possible it'd be good for you to learn the language, but their #1 goal is to keep you coming back. Oddly, Duolingo might not even be wrong to focus primariliy on keeping you moving forward, given how many people give up when learning a new language.
So, unless you have experience with this products that contradicts their claims, it's a good tutor by your definition.
The criticism of cliff's notes is generally that it's a superficial glance. It can't go deeper, it's basically a summary.
The LLM is not that. It can zoom in and out of a topic.
I think it's a poor criticism.
I don't think it's a silver bullet for learning, but it's a unified, consistent interface across topics and courses.
Sure, but only as long as you're not terribly concerned with the result being accurate, like that old reconstruction of Obama's face from a pixelated version [1] but this time about a topic for which one is, by definition, not capable of identifying whether the answer is correct.

It's unlikely to make up the same bullshit twice.
Usually exploring a topic in depth finds these issues pretty quickly.
If LLM's got better at just responding with: "I don't know", I'd have less of an issue.
Some topics you learn to beware and double check. Or ask it to cite sources. (For me, that's car repair. It's wrong a lot.)
I wish it had some kind of confidence level assessment or ability to realize it doesn't know, and I think it eventually will have that. Most humans I know are also very bad at that.
unavoidably, people who don't want to work, won't push the "work harder" button.
There is no way to learn without effort. I understand they are not claiming this, but many students want a silver bullet. There isn't one.
