I’m building a tool that helps you stay on track and revise LeetCode DSA problems in a structured, stress-free way for interview prep.

I have launched it here https://dsaprep.dev

Show HN: Spaced Repetition for LeetCode – Stop Forgetting Problems You've Solved

https://www.dsaprep.dev/

Hi HN,I built a spaced repetition system for Leetcode after realizing I'd "solved" 150+ problems but couldn't recall the patterns when faced with new questions in actual interviews.The problem: Solving problems once creates the illusion of learning without actual retention. Your brain discards solutions as "one-time knowledge" unless you review them at spaced intervals.What it does: -...

This is super cool — love the zero-codegen approach. I’ve had to deal with codegen hell in monorepos where a tiny .proto change breaks half the pipeline. Curious how this handles more complex types like nested messages or oneof fields?

Also, been building something in a different space (LeetCode prep tool), but the idea of removing build steps for dev speed really resonates. Would love to see how this could plug into a lightweight frontend setup.

How does the model gets trained?

Just trying to make learning more interactive. Is this the right way?

They python comment is fixed, thanks for testing it!

Well, I have seen in many of the other compilers that there is a limit on certain things, sometimes there is a limit on the number of lines, or number of executions, someone is asking for a sing-up etc. I tried to keep it completely free from any of these. That's why "freecodecompiler". (and I don't store the code)

Thanks! I will look into it.
