Build from Source

Prerequisites

• Rust (latest stable)
• Bun >= 1.0 (or Node.js >= 18)
• Platform-specific Tauri v2 dependencies (see guide)
• Ollama (optional — Ghost uses native AI by default)

Steps

# Clone the repo
git clone https://github.com/ghostapp-ai/ghost.git
cd ghost

# Install frontend dependencies
bun install

# Run in development mode
# (native AI model downloads on first run, ~23MB)
bun run tauri dev

Build for Production

# Desktop (Windows, macOS, or Linux — auto-detected)
bun run tauri build

# Android (requires Android SDK + NDK 27+)
bun run tauri android build --target aarch64

The desktop installer will be generated in src-tauri/target/release/bundle/.

Optional: Ollama for Higher-Quality Models

# Higher-quality 768D embeddings (vs 384D native)
ollama pull nomic-embed-text

# Agent reasoning model (for tool calling)
ollama pull qwen3:8b

System Requirements

Requirement	Minimum	Recommended
RAM	2 GB	8 GB+ (for larger chat models)
Storage	100 MB	500 MB+ (with AI models)
OS	Windows 10, macOS 10.15, Ubuntu 20.04	Latest versions
CPU	Any x86_64 or ARM64	AVX2/NEON SIMD support
GPU	Not required	CUDA/Metal for faster inference

First Launch

On first launch, Ghost will:

1. Show an onboarding wizard with hardware detection
2. Download the native AI model (~23MB) — requires internet once
3. Auto-discover your Documents, Desktop, Downloads, and Pictures folders
4. Start indexing files in the background

Subsequent launches are instant (<500ms) with the cached model.
