TOC for ChatAI

Resizable TOC sidebar + full-width left-aligned layout for ChatGPT, Gemini & Claude.ai. Navigate long AI chats instantly.

TOC for ChatAI gives you two things that make long AI conversations actually usable: 1. Resizable Table of Contents sidebar A clean sidebar that maps your entire conversation — every prompt you asked and every heading in the AI's response. One click jumps you straight to any point in the chat, no endless scrolling. - Works on ChatGPT, Gemini, and Claude.ai - Shows PROMPT 1, PROMPT 2… with the AI's section headings nested below - 3 outline modes: Prompts only, Top-level headings, or Detailed with full hierarchy - Tree-style connectors (├ └) show heading structure at a glance - Pin ★ any prompt or heading to keep it at the top — drag to reorder - Copy TOC to clipboard in Markdown or Plain text - Search and filter prompts by keyword - Collapse/expand individual groups or all at once - Jump to Top / Jump to Bottom buttons - Active scroll highlight — the TOC tracks where you are as you scroll - Hover any truncated text to see the full prompt or heading - Prompt count badge on the toggle button (☰ TOC · 14) - Light / Dark theme toggle — defaults to your system, remembers your choice - Resizable by dragging the left edge (width saved across sessions) - Keyboard shortcut: Ctrl+Shift+T (Mac: Cmd+Shift+T) - Pins, collapse state, and scroll position saved per conversation 2. Full-width, left-aligned layout (when TOC is open) By default, ChatGPT, Gemini and Claude.ai center their text in a narrow column, wasting the left side of your screen. When the TOC is open, the chat expands to fill the full available width. When you close the TOC, it reverts to the site's default layout. No account, no tracking, no data collection. Nothing is ever sent anywhere.
