Product summary

Review the store description, core capabilities, and common use cases.

Bring 400+ AI models to your Leetcode practice with a single OpenRouter API key. The extension can (with permission) read the problem you’re viewing and write back to your code editor—so you get targeted help without switching tabs. Perfect for learning efficiently and staying in flow on sites like LeetCode.

Features:

🔍 Learn Mode (default): Get 1–2 high-leverage hints first, never the full solution unless you ask—just like a real coach.

📝 Agent Mode: Let the AI safely propose edits in your code editor and review them with a VS Code–style diff (for models that support tool calling).

📐 Editor Text Selection: Highlight any text in your editor and ask the AI about it directly, without needing to copy-paste into the chat.

🔧 Custom Instructions: Add custom instructions to fine-tune the LLM's behavior to make it fit your needs.
