What it is

Jan is an open source language model that allows users to run a full-featured AI assistant locally, without internet connectivity. It's designed for developers and enthusiasts who need a powerful AI tool but prefer or require local execution.

Jan stands out as a fully local, open-source alternative for those needing AI capabilities without relying on cloud services, offering unparalleled privacy and control over data.

When it fits — and when it doesn’t

A good fit for

  • Teams working in environments with limited or no internet connectivity.

  • Developers interested in experimenting with AI locally without cloud dependencies.

  • Users concerned about privacy and data security who prefer offline solutions.

Look elsewhere if

  • Projects requiring real-time updates from the latest models.

  • Applications that need to scale across multiple devices or environments.

Known weaknesses

Each one links to the public issue, changelog or docs page it came from, where we have one.

  1. 01

    Limited integrations with other tools and platforms

    Community contributions are sparse, leading to fewer plugins or connectors available compared to more established frameworks.

  2. 02

    Resource-intensive for local execution

    Running Jan locally can consume significant CPU and memory resources, potentially impacting performance on less powerful machines.

What it does well

  • Runs entirely offline on your local machine.

  • Open-source and customizable for developers.

  • No internet required, ensuring privacy and security.
