Student Buddy — LeetCode Mentor

Student Buddy sits in a Chrome side panel while you solve a LeetCode problem. It helps you understand the question and think through an approach. It will not paste the full solution. Explain problem One complete answer for what the question is actually asking, with a walkthrough of the sample. Not a copy of the LeetCode prompt. Next hint One step at a time: naive idea → why it is slow → better idea → optimal pattern → edge cases. No class Solution, no key loop. Review my code Comments on bugs in your editor, then the next approach nudge. How to use 1. Open a problem on leetcode.com 2. Click the Student Buddy icon 3. Paste your own free Gemini API key in Settings (aistudio.google.com) 4. Refresh, then Explain or Hint Your key stays in Chrome on your account. The extension does not ship an API key and does not need a Python server. Student Buddy is a mentor, not an answer key.
