About

Navy — AI Browser Automation Agent

Navy is a browser automation agent built into Chrome. Type a goal in plain English — Navy carries it out by clicking, typing, scrolling, filling forms, switching tabs, running scripts, and more. No server required. No installation beyond loading the extension.


HOW IT WORKS

Navy attaches to your active tab, takes a screenshot, reads the page structure, and sends it to an AI model. The AI decides what action to take next. Navy executes it, takes another screenshot, and repeats until the goal is complete.

Because it runs inside your real browser session, Navy works with your existing logins, cookies, and saved state — no re-authentication needed.


LOCAL AND CLOUD AI

Navy supports both local and cloud AI providers.

Local (free, fully private — nothing leaves your machine):
• Run open-source models locally with Ollama or LM Studio. No account, no API key, no data sent anywhere.

Cloud:
• Navy works with any OpenAI-compatible API endpoint. Configure your preferred cloud AI service and API key in Settings. Swap providers at any time without reloading.


FEATURES

• Natural language goals — describe what you want in plain English
• Visual reasoning — numbered screenshot overlay lets the AI click precisely on specific elements
• Uses your real browser session — your logins and cookies are already there
• Two-tier planning — breaks complex goals into subtasks, re-plans dynamically when stuck
• Full action set — click, double-click, right-click, type, scroll, drag, hover, select dropdowns, fill and submit forms, fetch URLs, run JavaScript, manage tabs, upload files
• Panic stop — Ctrl+Shift+. (Cmd+Shift+. on Mac) immediately aborts any running task
• Audit log — every step is recorded locally for transparency


PRIVACY

With a local model: all processing is on your machine. Nothing leaves your device.

With a cloud provider: screenshots and page content are sent only to the API endpoint you configured. The extension developer never receives any of your data — there is no analytics, telemetry, or data collection of any kind.

Password fields and credential-like inputs are never sent to the AI.
