Itty Bitty AI

A lightweight AI-powered text editor built with Rust, egui, and llama.cpp.

It compiles to a web app or desktop app.

Features

• Modern, easy-to-use text editor
• Integrated AI text generation and analysis
• Cross-platform (desktop and web)
• Offline capable

Cross-Platform Architecture

Itty Bitty AI is built with a true cross-platform architecture:

• Single Codebase: Written in Rust and compiled to both native binaries and WebAssembly
• Desktop Native: Runs as a native application on Windows, macOS, and Linux with native performance and UI rendering
• Web Enabled: Compiles to WebAssembly and runs in any modern browser using Canvas-based rendering
• Consistent Experience: The same features and interface on all platforms thanks to egui's abstraction layer

The application use pure Rust immediate mode GUI framework that:

• Provides native-feeling interfaces on desktop platforms
• Renders via Canvas API when running in browsers
• Maintains the same look, feel, and functionality across all environments

Running the Application

Prerequisites

Make sure you have the latest version of stable Rust by running:

rustup update stable

Running on Web

You can compile and run the application as a web page:

1. Install the required target:

   rustup target add wasm32-unknown-unknown

2. Install Trunk:

   cargo install --locked trunk

3. Build and serve:

   trunk serve

4. Open http://127.0.0.1:8080/index.html#dev in your browser.

   • Adding #dev skips caching, allowing you to see the latest changes during development.

Running on Desktop

To run the application locally:

# Build and run in debug mode
cargo run

# Build and run in release mode (recommended for better performance)
cargo run --release

Linux Dependencies

On Ubuntu/Debian:

sudo apt-get install libxcb-render0-dev libxcb-shape0-dev libxcb-xfixes0-dev libxkbcommon-dev libssl-dev

On Fedora:

dnf install clang clang-devel clang-tools-extra libxkbcommon-devel pkg-config openssl-devel libxcb-devel gtk3-devel atk fontconfig-devel

Deployment

To build for web deployment:

1. Run trunk build --release
2. Deploy the generated dist directory to your preferred hosting service.

Development

This application is built with:

• egui for the UI framework - a portable immediate mode GUI framework written in Rust
• eframe-template for the eframe boilerplate
• candle for the machine learning backend
