    description
    Stay in problem-solving mode. LeetBuddy lives in the Chrome side panel and acts like a technical interviewer: it won't hand you full solutions; it nudges you to derive them yourself.
                                                                                                                                                                                                                                                                            
    Key Features                                                                                                                                                                                                                                                          
    
    - Context-aware AI chat tied to the current LeetCode problem
    - Automatic problem detection — switches context when you navigate to different problems
    - Strict "no full answers" interview persona — guides you without spoiling solutions
    - Quick hint buttons for targeted help
    - Automatic submission tracking — detects when you solve a problem and records your progress
    - Built-in stopwatch — manually track timing when solving in your IDE, on paper, etc.
    - Multi-attempt history — review all your attempts per problem with timestamps
    - Model selection — choose from Gemini 2.5 Flash, 2.5 Pro, 3 Flash, or 3 Pro
    - Configurable thinking modes — control reasoning depth for different models
    
    How It Works
    
    1. Install the extension
    2. Open the LeetBuddy side panel while viewing a LeetCode problem (click the extension icon)
    3. Set your Google AI Studio API key in the extension's Options page
    4. Chat, ask for hints, and refine your approach
    5. When you submit a correct solution, LeetBuddy automatically prompts you to save it
    6. Review your progress and solving history in the Review tab
    
    Privacy & Data

    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)
