Leet AI

Leet AI is a Chrome extension that provides step‑by‑step hints and feedback while solving problems on LeetCode. It integrates with generative AI models so you can ask for guidance directly from the problem page.

Features

• Chat interface to discuss problems and receive short hints
• Supports multiple models including OpenAI GPT‑3.5 Turbo, GPT‑4o and Google Gemini 1.5 Pro
• Remembers your conversations locally using IndexedDB
• Quickly switch models or clear chat history
• Configure API keys through the popup

Requirements

• Node.js 18 or higher (tested with Node 22)
• pnpm (preferred) or npm for dependency management

Getting Started

Install dependencies and start the development server:

pnpm install      # or `npm install`
pnpm run dev

The extension files will be built in watch mode. To test it in Chrome:

1. Open chrome://extensions
2. Enable Developer mode
3. Choose Load unpacked and select the dist/ directory generated by Vite

Building for Production

Generate an optimized build:

pnpm run build    # or `npm run build`

This outputs the packaged extension to the dist/ folder. Load this folder in Chrome as described above.

• pnpm run lint – run ESLint
• pnpm run prettier – format source files
• pnpm run preview – preview the production build
