Lemda AI 🧠

Nepal's First Autonomous AI Terminal Agent

Lemda AI is a powerful, production-ready coding assistant that lives directly in your terminal. With a beautifully designed Terminal User Interface (TUI), native PC access, and a multi-model gateway, Lemda acts as your AI peer programmer, capable of executing commands, reading files, writing code, and answering complex queries.

🚀 Features

• Beautiful TUI: Built with Rust (ratatui and crossterm), featuring a live status bar, visible cursor, chunked typing effects, and message queueing.
• Multi-Model Gateway: Connects to multiple LLMs seamlessly. Supports:
  • Gemini 2.5 Flash (Advanced, FREE)
  • Gemini 2.5 Pro (Ultra, PRO)
  • Gemini 2.0 Flash Lite (Fast, FREE)
  • DeepSeek V4 (Reasoning, FREE)
• Local PC Access: True autonomous capability. The agent can use tools like run_shell, read_file, and write_file to navigate your computer, check your OS, and write real code to your hard drive.
• Interactive Command Menu: Type / to open a dynamic popup menu to switch models, change levels, and access more modes on the fly.
• Auto-Sync Authentication: Simple browser-based login flow. Paste your API key in the browser and watch the terminal automatically sync and boot up.

🛠️ Quick Start

1. Setup the Backend Proxy

The backend handles routing requests to Google Gemini and DeepSeek securely.

1. Navigate to the UI folder and create an .env file:

   cd apps/ui
   touch .env

2. Add your API keys to apps/ui/.env:

   GEMINI_API_KEY=your_gemini_key_here
   DEEPSEEK_API_KEY=your_deepseek_key_here

3. Start the backend server:

   cd crates/backend
   cargo run

2. Install and Run the CLI

The CLI is your primary interface. Install it globally on your machine:

cd crates/cli
cargo install --path . --force

Now, simply open any terminal window and type:

lemdaai

3. Usage

• Type natural language prompts and press Enter.
• Use the Up/Down arrows to navigate chat history (Coming Soon).
• Type / to open the Command Menu.
• Select /model to switch between Gemini and DeepSeek.
