Threadline

Threadline:
A Chrome extension that adds a navigable table of contents sidebar to Claude.ai and ChatGPT chat threads.

Problem:
Long AI chat conversations become difficult to navigate. Scrolling through 50+ message exchanges to find a specific topic is tedious and time-consuming.

Solution:
Threadline adds a fixed sidebar that displays all your message exchanges as a clickable table of contents. Jump to any part of the conversation instantly.

Features:
- Visual timeline - See all conversation exchanges at a glance with numbered entries
- Click to navigate - Jump to any message instantly with smooth scrolling
- Hover previews - See full message preview in tooltip before clicking
- Auto-updates - New messages appear in real-time as you chat
- Theme aware - Automatically matches light/dark mode
- Collapsible - Minimize to a small icon when not needed
- Smart positioning - Adjusts when you toggle the site's sidebar
