Exdraft is a website, but in essence it is web-based software that provides full step-by-step solutions to math problems typically encountered in first year university.
The cool part is that you can plug in your own values for these problem templates, and obtain worked solutions to your specific problem. And you can also save your collection of problems, generic or customized and share links to your solutions with whomever you wish.
The website/software is still undergoing development, but there's a fair amount of linear algebra content there already. Calculus will be added soon, as well as other software features.

Exdraft - University math is easy. You just need to see the pattern.
I see your point. It certainly makes it very easy to get your homework done. But as with most things in life, I believe there's a tradeoff. Pros and cons.
I think there's a lot of good from having ready access to the solutions of standard problems. For one thing, by plugging in different input values, and seeing the solution done over and over, it helps to recognize the problem/solution pattern.
