LeetBuddy

LeetBuddy: Technical Interview Practice LeetBuddy is a Chrome side panel extension that turns LeetCode practice into a structured technical interview. Instead of providing full solutions, it acts as an interviewer—guiding you through the problem-solving process, challenging your logic, and evaluating your performance. Interactive Interviewing * Hint-Based Guidance: A strict "no spoilers" persona that uses targeted questions to help you derive the optimal solution yourself. * Structured Flow: Moves through realistic interview stages—discussing the algorithm and complexity before you start coding, followed by implementation and optimization. * Performance Assessment: After solving, receive a "Hire/No Hire" evaluation with a detailed breakdown of your technical strengths and areas for improvement. Deep Integration * Code-Aware Feedback: Use the "Attach Code" feature to let the AI analyze your current implementation for logic errors or edge cases without giving away the answer. * Automatic Detection: Instantly switches context as you navigate between LeetCode problems. * Submission Tracking: Automatically detects when you pass all test cases and prompts you to save your attempt, timing, and interview notes. Progress & Analysis * Topic Heatmap: Visualize your coverage and proficiency across categories like Dynamic Programming, Graphs, and Trees. * Detailed History: Review all past attempts, including code snapshots, solve times, and interviewer feedback. * Rich Formatting: Full KaTeX support for clear, readable math and algorithmic notation. Advanced AI Control * Gemini 3 Support: Access the latest models with controllable "Thinking Levels" to adjust the depth of the AI’s reasoning. * Thinking Budgets: Fine-tune model behavior for faster responses or deeper architectural analysis. How It Works 1. Setup: Open the side panel and add your Google AI Studio API key in the Options page. 2. Practice: Start a problem. Discuss your approach with the AI to get the "Go-Ahead" to code. 3. Refine: Use the "Attach Code" button if you get stuck on a specific logic gate. 4. Review: Complete the interview to get your assessment and track your progress in the Review tab. Privacy & Data * Local Storage: Your API key and all history are stored locally on your device via chrome.storage.local. * Direct API Calls: All communication happens directly between your browser and the Gemini API. There are no middleman servers. * No Tracking: No analytics or data collection. Requirements * A free API key from Google AI Studio (https://aistudio.google.com/apikey) * Chrome or Edge browser
