How to Set Up and Use Jarvis
Jarvis is a fully offline, privacy-first AI voice assistant that runs entirely on your local machine using Ollama as the inference backend. It listens for your voice, understands natural conversation context without requiring you to repeat yourself, and can search the web via DuckDuckGo, read your screen via OCR, track nutrition and health goals, control Chrome, and connect to 500+ external services via MCP integrations. Unlike cloud-based assistants, Jarvis stores everything locally and redacts sensitive information before persisting conversation history, making it suitable for users who need AI assistance without sacrificing data privacy.
Prerequisites
- Ollama installed and running locally (https://ollama.com/download)
- At least one language model pulled in Ollama (e.g. ollama pull llama3)
- macOS, Windows, or Linux with microphone access
- Chrome browser (for browser control features)
- Sufficient RAM for local LLM inference (8GB minimum, 16GB+ recommended)
Install Ollama and pull a model
Download and install Ollama, then pull a language model to use as Jarvis's brain. Llama 3 or Mistral work well for conversational use.
# After installing Ollama from https://ollama.com/download
ollama pull llama3Download the Jarvis application
Download the latest Jarvis release for your platform from the GitHub releases page. No compilation is required — pre-built binaries are provided.
# macOS: move to Applications and right-click to open

}Install as MCP server via npx (alternative)
Alternatively, run Jarvis as an MCP server to integrate it with Claude Desktop or other MCP clients.
npx -y jarvisConfigure MCP client integration
Add Jarvis to your Claude Desktop configuration to use its voice and memory capabilities as MCP tools inside your AI assistant.

}Prompts to try
Example voice commands and text prompts you can use once Jarvis is running.
- "Jarvis, what did I say about the project deadline last week?"
- "Should I eat pizza tonight considering my health goals this week?"
- "Search for the latest TypeScript 5.0 features"
- "Read what's on my screen and summarize it"
- "Set a dictation reminder for my meeting notes"Troubleshooting Jarvis
Jarvis does not respond to voice — microphone not detected
On macOS, grant microphone permissions to Terminal or the Jarvis app in System Settings > Privacy & Security > Microphone. On Linux, ensure PulseAudio or PipeWire is running and the correct input device is selected.
Ollama connection refused / model not found
Ensure Ollama is running with 'ollama serve' and that you have pulled a model with 'ollama pull llama3'. Check that Ollama is listening on the default port 11434.
Web search returns no results or errors
Ensure web_search_enabled is set to true in ~/.config/jarvis/config.json. If DuckDuckGo is blocked on your network, Jarvis will fall back to Brave Search and Wikipedia automatically.
