Chat with Claude to control your browser Porthole for Claude puts an AI assistant in your browser's side panel with direct access to the page you're viewing. Ask Claude to read, interact with, or automate anything on the current page — in plain English. WHAT IT CAN DO • Read and extract content from any page • Click, fill, and submit forms • Take screenshots and analyze them • Monitor network requests and API calls • Read and write cookies and local storage • Search and manage your browser history • Download files and open reports • Record multi-step workflows and replay them • Create and close tabs, navigate between pages HOW IT WORKS Open the side panel, enter your Anthropic API key in Settings, and start chatting. Claude calls browser tools directly — no intermediary server. All data stays local except the conversation sent to api.anthropic.com with your own key. PRIVACY No telemetry. No tracking. No data collection. Your API key is stored locally in chrome.storage.local and never leaves your machine.
