# Ensu > Ensu is a local LLM app by Ente that lets you run and chat with AI language models entirely on your own device, with full privacy. Ensu is a privacy-first local LLM application built by Ente that lets you run large language models directly on your own device — no data ever leaves your machine. It is part of Ente's open-source ecosystem, designed for users who want the power of AI assistants without sacrificing privacy or relying on cloud services.
