I built AlgoDrill because I kept grinding LeetCode, thinking I knew the pattern, and then completely blanking when I had to implement it from scratch a few weeks later.

AlgoDrill turns NeetCode 150 and more into pattern-based drills: you rebuild the solution line by line with active recall, get first principles editorials that explain why each step exists, and everything is tagged by patterns like sliding window, two pointers, and DP so you can hammer the ones you keep forgetting. The goal is simple: turn familiar patterns into code you can write quickly and confidently in a real interview.

Would love feedback on whether this drill-style approach feels like a real upgrade over just solving problems once, and what’s most confusing or missing when you first land on the site.

I understand the pragmatic reasons behind such a decision, but insisting that I sign up with Google (and only Google) was an unfortunate blocker.

If anything, GitHub seems like a more obvious choice for such a site.

That is fair. I went with Google first because it let me ship the first version quickly, but for a tool aimed at developers GitHub and simple email sign in make much more sense.

I am working on both and plan to let people move their account once they are live if they would prefer not to use Google here.
