What is AI Coding Tutor

From the Chrome Web Store

AI coding companion for LeetCode & HackerRank. Supports OpenAI & Gemini. Hints, code review, voice chat, and interview practice. Your personal coding companion designed specifically for career switchers and beginners.

🚀 Overview The AI Coding Tutor is a personal, interactive coding companion designed to help you learn concepts, not just copy answers. It lives directly inside your browser as a floating overlay on LeetCode and HackerRank, providing real-time guidance, literal code tracing, and interview practice.

✨ Key Features: 🧠 Interactive Learning:

Socratic Method: The AI doesn't just give you the answer. It asks follow-up questions to test your understanding (e.g., "Now that we fixed the loop, what happens if the array is empty?").
Literal Code Tracing: Prevents confusion by tracing your code exactly as written, highlighting logic errors like off-by-one bugs or loop termination issues step-by-step.
Business Analogies: Explains complex algorithms using relatable scenarios (e.g., "Think of a HashMap like a library card catalog...").

🗣️ Voice & Interview Practice: 🎙️ Voice Input: Click the microphone to speak your questions or explain your logic naturally. 🔊 Text-to-Speech (TTS): Enable the speaker toggle to hear the AI's response read aloud. Practice Interview Mode: Simulate a real whiteboard interview. Explain your approach verbally, and the AI will critique your communication, clarity, and technical accuracy.

🎨 Professional UI Floating Overlay: A non-intrusive, draggable panel that stays with you as you code. Smart Layout: Tightly integrated UI that never blocks critical platform features. Dark/Light Mode: Automatically syncs with your preference or can be toggled manually.
