AI Chat TOC

A minimal table-of-contents sidebar for Claude and ChatGPT conversations.

AI Chat TOC adds a lightweight table-of-contents sidebar to long Claude and ChatGPT conversations. It lists your own messages in order, so you can jump back to earlier questions without manually scrolling through the entire thread. The sidebar stays collapsed by default, follows the host page theme, and only appears on supported conversation pages. Core features: - User-message table of contents for long conversations - Click any item to jump back to that message - Current visible message highlight while scrolling - Default collapsed tab to avoid covering the chat - One-time tab discovery hint after installation - Automatic light and dark theme matching - Works on Claude and ChatGPT conversation pages Privacy: - No account system - No analytics - No external API calls - No message upload - No local or remote storage of conversation content - Visible conversation text is processed locally on the page to build the table of contents - Only a local boolean flag is stored to avoid showing the one-time tab discovery hint repeatedly AI Chat TOC is not affiliated with Anthropic, Claude, OpenAI, or ChatGPT.
