Jan - Local AI Assistant

Jan AI

Jan is an AI assistant that can run 100% offline on your device. Download and run LLMs with
full control and privacy.

Installation

The easiest way to get started is by downloading one of the following versions for your respective operating system:

Download from jan.ai or GitHub Releases.

Features

  • Local AI Models: Download and run LLMs (Llama, Gemma, Qwen, etc.) from HuggingFace
  • Cloud Integration: Connect to OpenAI, Anthropic, Mistral, Groq, and others
  • Custom Assistants: Create specialized AI assistants for your tasks
  • OpenAI-Compatible API: Local server at localhost:1337 for other applications
  • Model Context Protocol: MCP integration for enhanced capabilities
  • Privacy First: Everything runs locally when you want it to

Build from Source

For those who enjoy the scenic route:

Prerequisites

  • Node.js ≥ 20.0.0
  • Yarn ≥ 1.22.0
  • Make ≥ 3.81
  • Rust (for Tauri)

Run with Make

git clone https://github.com/menloresearch/jan
cd jan
make dev

This handles everything: installs dependencies, builds core components, and launches the app.

Available make targets:

  • make dev - Full development setup and launch
  • make build - Production build
  • make test - Run tests and linting
  • make clean - Delete everything and start fresh

Run with Mise (easier)

You can also run with mise, which is a bit easier as it ensures Node.js, Rust, and other dependency versions are automatically managed:

git clone https://github.com/menloresearch/jan
cd jan

# Install mise (if not already installed)
curl https://mise.run | sh

# Install tools and start development
mise install    # installs Node.js, Rust, and other tools
mise dev        # runs the full development setup

Available mise commands:

  • mise dev - Full development setup and launch
  • mise build - Production build
  • mise test - Run tests and linting
  • mise clean - Delete everything and start fresh
  • mise tasks - List all available tasks

Manual Commands

yarn install
yarn build:tauri:plugin:api
yarn build:core
yarn build:extensions
yarn dev

System Requirements

Minimum specs for a decent experience:

  • macOS: 13.6+ (8GB RAM for 3B models, 16GB for 7B, 32GB for 13B)
  • Windows: 10+ with GPU support for NVIDIA/AMD/Intel Arc
  • Linux: Most distributions work, GPU acceleration available

For detailed compatibility, check our installation guides.
