Written mid-degree, not after it

Study Stack is a small notebook of what actually works — AI tools, study systems, and small tech side-hustles — written by a second-year student figuring it out in real time, not a guru looking back on it years later.

Everything here gets tested before it's written up. If a tool doesn't earn a place in the weekly routine, it doesn't get a post.

Have a tool worth testing? Say so — this list is never finished.
