CrustAI – Private local AI assistant that runs entirely on your own machine without sending data to the cloud

CrustAI is a self-hosted AI assistant built with Node.js and powered by Ollama (a local LLM runtime) that connects to Telegram, WhatsApp, Discord, and Slack while keeping all data on your machine.

The system supports multiple open-source models including llama3.2, tinyllama, and phi3, offers long-term memory to retain facts across conversations, and includes offline voice support for Portuguese and English.

All conversations remain private on the user's machine with no cloud storage, no API calls to external services, and open-source code available for inspection.
