GhostOS

GhostOS is a featherweight (<35MB RAM), 100% offline desktop AI assistant and companion designed for developers and privacy-conscious users.

Unlike heavy Electron-based desktop AI clients that consume 1GB+ of memory before you even type a prompt, GhostOS is built with an agile Python core and native OS WebViews (WebKit / WebView2).

Key Features: • Featherweight Footprint: Idles at <35MB RAM (95% lighter than Electron apps). • 100% Offline & Private: Zero telemetry, zero cloud tracking, and air-gapped readiness. • Dynamic VRAM Juggler: Smart memory offloading to keep laptop fans silent and GPUs cool. • Zero-DB RAG: Ingest local documents, codebases, and PDFs using pure SQLite FTS5 without spinning up heavy vector databases. • Terminal Sandbox Lens: Proactive safety interceptor for terminal commands before execution. • Floating Casper HUD: A transparent desktop companion with RPG progression and custom skins (Glass, Cyberpunk, Gold, Matrix). • Seamless Ollama Support: Connects to local Ollama models (Qwen, Llama, DeepSeek) or runs standalone.
