Solve real AI/ML problems. 15 minutes a day.
Build skills that stick.

No setup. No boilerplate. Just code.
Real bugs from real codebases. A broken training loop, a RAG pipeline returning garbage, an inference endpoint that's way too slow.
Full editor. numpy, pytorch, sklearn loaded. No boilerplate, no setup. Just you and the bug.
Submit, get a verdict in seconds. Green or red. If it failed, you see exactly which tests broke and why.
You don't need another 40-hour course. One focused problem a day builds more intuition than a week of lectures.
Not fizzbuzz with tensors. Debug a training loop that silently converges to garbage. Fix a retrieval pipeline that hallucinates. Ship code that works.
Spaced repetition is baked in. Problems come back at the right time so you don't lose what you built.
“I mass-applied and bombed every AI interview for months. Started doing one NeetAI problem a day, got an offer at Stripe six weeks later.”

ML Engineer at Stripe
“Most platforms teach you the theory and leave you to figure out the rest. This one makes you write the code. That's the difference.”
James Okafor
Senior Engineer at Meta
“I kept forgetting everything I studied. The spaced repetition here fixed that. I actually retained what I learned three months ago.”
