LeetCode Reviewer
For Interview Prep

LeetCoach is a code reviewer sitting as a chrome extension in the sidebar, teaching you DSA concepts, highlighting bugs, and asking questions about what you wrote like an interviewer would.

Stop context-switching. LeetCoach reads your code, submission results, and problem descriptions directly from LeetCode. No more copy-pasting into ChatGPT.

Progressive Hints

We won't just give you the answer. LeetCoach uses progressive hints to help you figure it out on your own. It starts by pointing you in the right direction, then reveals the algorithmic pattern, and finally the data structure. It's built to train your problem-solving skills the way a senior engineer would guide you.

Code Analysis

LeetCoach reviews your code to catch bugs and edge cases while calculating your Big-O time and space complexity. It compares your solution against the optimal approach, so you can learn how to write production-ready code instead of just passing the basic test cases.

DSA Guidance & Chat

If you're stuck on a tricky algorithm, LeetCoach can act as your technical interviewer. It identifies the optimal patterns and asks you questions to challenge your logic. You'll have to defend your engineering trade-offs, giving you practice for real FAANG interviews.

Visual Diagrams

Algorithms are hard to follow in your head. LeetCoach generates tree structures, state machines, flowcharts, and more right in the sidebar, so you can actually see what's happening instead of trying to trace through it mentally.

Session Review Reports

After you finish a problem, LeetCoach generates a full debrief. It covers how you approached it, where you got stuck, what the optimal solution looks like, and which patterns you should practice next. It's the honest feedback you'd get from a great mentor.
