## Jan Local AI Key Advantages
- 44,982+ GitHub stars running 100% offline with built-in C++ Cortex/llama.cpp inference (Metal, CUDA, Vulkan) and automatic VRAM hardware detection
- Exposes a drop-in OpenAI-compatible HTTP server at `localhost:1337/v1` so IDE agents and scripts can query local GGUF models for $0
- Stores all conversations, embeddings, and attachments in plain local filesystem folders (`~/jan`) with zero cloud telemetry

## Chatbox AI Key Advantages
- 42,051+ GitHub stars with native desktop (macOS/Win/Linux) plus iOS and Android apps for unified BYOK API key usage anywhere
- Ultra-fast 68MB footprint with instant switching between Anthropic Claude, OpenAI, DeepSeek-R1, Gemini, and remote Ollama endpoints
- Built-in Markdown/LaTeX math rendering, Mermaid diagram preview, webpage/PDF context parsing, and local prompt library
