ChatGPT Backend TOC

A lightweight Userscript that adds a collapsible Table of Contents sidebar to ChatGPT.

🚀 Why this script?

Most navigation extensions try to read the headers from the current webpage HTML. However, ChatGPT uses "lazy loading" (virtualization), meaning messages scroll off-screen are often removed from the code to save memory. This causes other extensions to "lose" parts of the conversation.

This script is different. It fetches the conversation data directly from ChatGPT's internal Backend API. This means:

It loads the entire conversation map instantly.
It never misses a header, even in extremely long chats.
It forces the browser to jump to the correct message ID, triggering the render on demand.

✨ Features

100% Complete: Navigates the full history, not just what is currently visible.
Deep Navigation: Detects Markdown headers (#) and Bold Text as clickable sub-sections.
Smart Scrolling: Calculates the correct scroll position so text doesn't hide behind the top header bar.
Clean UI:
- Resizable sidebar (drag the edge).
- Distinct icons for User (Gray) vs. AI (Green).
- Expand/Collapse arrows for nested content.
- Long titles auto-expand when you widen the sidebar.

Credits

Heavily inspired by the Scroll Extension by Asker Kurtelli. This version was ported to a Userscript to utilize direct API fetching and reduce the need for a full browser extension.
