Jan - AI Local Applications Tool

Overview

Jan is an open-source, 100% offline ChatGPT alternative that provides a desktop application UI for interacting with local large language models. According to the GitHub repository (https://github.com/menloresearch/jan), Jan is built to run entirely on-device so conversations, model files, and inference never leave the user’s machine, making it suitable for privacy-sensitive use cases and environments without reliable internet. The project focuses on a simple chat interface for desktop users who want to run local LLMs without relying on cloud APIs. Jan's architecture is centered on loading user-provided model files and running inference locally through compatible backends; the repository contains the source code, documentation, and installation/build instructions. Because Jan is open-source, developers can inspect, modify, or contribute to the codebase and adapt the app for specific local workflows or integrations.
