Page Save Bridge

Give AI coding assistants the ability to save and read any browser tab — even sites that block automation tools.

The Problem

Claude Code, Cursor, and other AI tools use browser automation to read web pages. But sites like Reddit, Twitter/X, and LinkedIn block these tools with Content Security Policy. Your AI can see the tab exists but can't read the content.

The Solution

Page Save Bridge uses chrome.pageCapture.saveAsMHTML() — a browser-engine-level API that operates below Content Security Policy. It captures the fully rendered page with your existing sessions, cookies, and authentication intact. There is nothing for the website to block.

Install

1

Chrome Extension

Install from the Chrome Web Store, or load unpacked from the source.

2

Node.js Bridge

npx page-save serve

Starts the local WebSocket server on port 7224. Your AI calls this via Bash.

Usage

# List all open Chrome tabs
npx page-save tabs

# Save a Reddit page as MHTML
npx page-save save --tab reddit

# Extract plain text from any tab
npx page-save text --tab reddit

# Save the currently active tab
npx page-save save

Keyboard shortcut: Press Alt+S to save the active tab instantly.
