Jan is a desktop AI app for macOS that lets you chat with models, run local AI workflows, and connect external tools from one workspace.
What is Jan?
Jan is a native desktop AI application for macOS that helps people run and use AI models from a single workspace. It supports local AI use on your own hardware and can also connect to compatible cloud or custom model providers when you want broader model options. Common uses include chatting with AI, organizing work into projects, creating custom assistants, and extending workflows with external tools and connectors. Jan also includes a local API server and command-line tools that can fit into developer and advanced productivity setups. It is designed for users who want more control over how models run, where data is stored, and how AI features connect with files, tools, and everyday desktop tasks. JAN AI PTE. LTD. publishes Jan as part of a broader local-first AI platform.

Safety overview
Status: Mostly safe
Jan is legitimate desktop AI software, but it can handle conversations, files, model downloads, and optional external tool connections, so the privacy impact depends on how you use it. Local use is normal for this type of app and can reduce cloud exposure, while connected providers or tool integrations may send data beyond your Mac according to your setup. Expect storage use for models, chats, settings, and logs. Keep the app only if you use its AI features, and review any connected providers or tools before giving them access to sensitive work.
Recommendation: Keep Jan if you use local or connected AI on your Mac. If you no longer use it, you can remove the app and its data to recover space, but doing so may delete downloaded models, conversation history, saved settings, and custom workflow setup.
