Hefty Documentation

Hefty is a personal AI assistant that helps you get things done on your computer. Tell it what you need, and it takes care of the rest - organizing files, looking things up, handling repetitive tasks, and more. It runs privately on your machine.

All your data stays on your computer. To power the AI, you can choose from four supported providers - Ollama and LM Studio run on your machine for free, or connect to cloud services like OpenAI or Anthropic.

What Makes Hefty Different

• Does the work for you - opens apps, organizes files, browses the web, and handles tasks on your behalf
• Gets better over time - learns what works and what doesn't, so it becomes more helpful the more you use it
• Remembers what you're working on - picks up where you left off, even across sessions
• You're always in the loop - see every action in real-time and stay in control
• Your data stays yours - runs privately on your machine, with local or cloud AI providers
• Connects to your tools - extend Hefty with plugins and integrations for the services you already use

How It Works

You chat with Hefty through a clean web interface. When you send a message, Hefty goes through a few quick steps behind the scenes:

Results stream back in real-time as Hefty thinks, plans, acts, and reflects. The entire process is visible in the UI.
