Three steps to local automation
Install the desktop app
Download the installer for your OS, open it, and launch urNova from your menu bar or system tray.
Add your Anthropic key
Your API key is stored in the OS keychain (Stronghold). urNova never sees it on our servers.
Automate from the web
Open urnova.org, type a task, and run. The site detects Privacy Mode and routes the job locally.
What stays on your device
- LLM API key and browser session
- Cookies, logins, and form data
- Agent thoughts, clicks, and screenshots
- Run history on disk (optional export)
Your prompt still goes to Anthropic from your network when you run a task. The agent also loads public websites normally. Read the full privacy policy.
Build from source
