Teabag is a free Chromium extension that adds AI code review to LeetCode. Open any submission and click Teabag it to get an instant breakdown of your solution.

You'll see the algorithmic paradigm you used versus the optimal one, your time and space complexity against the best achievable Big-O bounds, and a code-quality score with concrete strengths and improvements.

Built for DSA practice and coding-interview prep, it runs on Inception's Mercury Decide model through the OpenRouter Decisions API, returning typed, confidence-scored verdicts instead of vague prose.

Results are cached per submission, the card matches LeetCode's dark and light themes, and your OpenRouter API key stays in local browser storage.
