Developer comments

This extension uses ChatGPT's backend API (not DOM scraping) to fetch conversation data for reliable output. All processing happens locally — no external servers are involved, and no user data is collected, transmitted, or stored outside your browser.

The extension is built with TypeScript and bundled with Vite. Source code is fully available on GitHub.
