AI ChatNav

Navigate between user and AI messages in ChatGPT, Claude.ai, and other AI chat interfaces

Stop scrolling, start jumping! AI ChatNav adds keyboard-driven navigation to your ChatGPT and Claude.ai conversations so you can jump directly between messages. Long AI conversations are hard to navigate. You asked something 30 messages ago, but finding it means scrolling past walls of text, code blocks, and images. AI ChatNav solves this with a compact floating widget (that you can hide) and keyboard shortcuts that let you jump between messages instantly. THREE NAVIGATION MODES - User messages only - jump between your prompts - AI messages only - jump between responses - Both - navigate every message in order KEYBOARD SHORTCUTS Navigate without touching the mouse: - Alt+J / Alt+Down: Next message - Alt+K / Alt+Up: Previous message - Ctrl+Alt+J (or Down): Jump to last message - Ctrl+Alt+K (or Up): Jump to first message - Alt+M: Cycle mode (User / AI / Both) - Alt+O: Expand/collapse current message - Ctrl+Alt+O: Toggle auto-expand and expand/collapse all - Alt+H: Hide/show widget SMART WIDGET - Compact two-row floating panel with position indicator (e.g., "3/12") - Positions itself next to the text input bar automatically - Stays visible when switching between conversations - Hides when you view images or open dialogs - Only appears when there are messages to navigate AUTO-EXPAND (Claude.ai) Long messages that Claude truncates with "Show more" can be auto-expanded as you navigate. Toggle with Ctrl+Alt+O or use the widget button to expand/collapse all at once. THEMES - Light theme - blends with ChatGPT and Claude's default look - Dark theme - for dark mode users - Auto-detect - matches your site's current theme automatically SUPPORTED PLATFORMS - ChatGPT (chatgpt.com) - Claude.ai (claude.ai) - More platforms planned (Gemini, Copilot, and others) HOW TO USE 1.

AI ChatNav works with both ChatGPT (chatgpt.com) and Claude.ai (claude.ai). More platforms are planned. * Do I need an account? No. Install and use immediately. No sign-up, no login. * Will my keyboard shortcuts conflict with the site's shortcuts? The extension uses Alt-based shortcuts which don't conflict with ChatGPT or Claude's built-in shortcuts. * Can I change the theme? Yes. Choose Light, Dark, or Auto-detect in the settings. Auto-detect matches whatever theme the site is using. * What does the ~ symbol mean in the counter? When you switch modes (e.g., from User to AI), the counter may show ~3/8 with a tilde. This means you're approximately at that position but haven't navigated there yet. Your next up/down action will take you to the correct message. * Is my data secure? Yes. AI ChatNav operates entirely within your browser. No data ever leaves your device. SUPPORT Have questions or found a bug?
