Lattice AI local MLX/cloud LLM workspace server

Your personal AI workspace server — local & cloud, one stack.

What is Lattice AI?

Lattice AI is a self-hosted AI server that unifies local and cloud LLMs into one workspace — web chat, VS Code extension, Telegram bot, and MCP tools, all from a single pip install.

• 🖥️ Web UI — chat, file upload, admin dashboard, data graph
• 🧩 VS Code / Cursor extension — edit, explain, generate commands inline
• 📱 Telegram bot — access your AI from anywhere
• 🔌 MCP server — use Lattice tools inside Claude Desktop / Cursor
• 🔒 Zero telemetry — all data stays in ~/.ltcai/ on your machine

ModuleNotFoundError: mlx	MLX not installed	pip install "ltcai[local]" (Apple Silicon only)
Python < 3.11	Version mismatch	Upgrade: python3 --version
LTCAI doctor OPTIONAL	Optional dep missing	Safe to ignore if feature not needed
No API key warning	Cloud model not set	OPENAI_API_KEY=sk-... LTCAI or set in admin panel
Can't reach from iPad	Default bind 127.0.0.1	LATTICEAI_HOST=0.0.0.0 LTCAI or use --tunnel
