AI Coach for LeetCode

Learning mode for LeetCode: hints, code review, a hot-cold bar and 17 step-by-step algorithm patterns, on the AI model you choose.

🧠 AI Coach for LeetCode turns LeetCode into a learning session. A panel next to every problem helps you solve it yourself, instead of handing you the answer. 🪜 A ladder of hints: a guiding question, then a hint, then a plan. The full solution only on a double click. 📖 Explain problem: the task in plain words, with the first example walked through. 🔍 Code review: bugs, edge cases and complexity of your current code, without rewriting it. 🧪 Find a failing test: one valid input your code fails, ready to paste into Testcase. 🌡️ Hot-cold: a bar that shows, while you code, how close you are to a working solution. 💬 Chat: share an idea and the coach helps you check it with a guiding question, without spoilers. ⏱️ A timer that starts when you start coding or press ▶, with limits per difficulty. 📈 History of solved problems: time, hints, submissions. 🧩 Patterns: 17 algorithm patterns, from two pointers to dynamic programming, each run step by step on an example with pseudocode. No AI needed. 🤖 Your choice of AI: Claude, OpenAI or hundreds of OpenRouter models with your own API key, or a free model on your own computer through Ollama or LM Studio. The extension is free; you pay your provider directly. 🌍 Interface and answers in English, Spanish, Italian, French, German and Russian. 🔒 Private by design: keys stay in your browser, closed to web pages, and go only to the provider you chose. No servers of ours, no tracking. 🏆 Fair play: the coach switches off on contest pages. Not affiliated with LeetCode.
