I've been self-teaching coding and math for years. Here's what I've learned about why most people quit:

They study passively. Watching a 4-hour YouTube tutorial feels productive but retains almost nothing. Research shows active recall — testing yourself — beats passive review by 3-5x.

They don't have feedback loops. When you're stuck on a problem at 2am, there's no one to ask. You spiral, get frustrated, and close the laptop.

They follow someone else's curriculum. Generic courses force you through material you already know while skipping what you actually need.

That's why I built TutorStack — an AI tutor that adapts to YOUR gaps, gives you instant feedback, and generates practice problems at your exact level.

It's not another course. It's a tutor that's always available, never judges, and actually gets smarter about how you learn over time.

If you're teaching yourself coding, math, or any technical skill — this is built for you.
