ChatDot - AI Chat Navigator

Long conversations in ChatGPT and other AI tools quickly become hard to navigate. Finding a specific prompt or reconstructing the surrounding context usually means endless scrolling and broken focus. ChatDot adds a lightweight floating sidebar and message outline panel to supported AI chat pages, so you can move through long threads the way you scan a document outline. On ChatGPT, it also adds a conversation trim mode that keeps only the latest N turns visible to reduce page weight in very long chats. Key features: Floating outline panel: extracts your prompts into a clickable conversation index. Quick navigation: jump to the top, bottom, previous, or next user message. Hover previews: inspect nearby prompt content before you jump. ChatGPT conversation trim: manually trim, restore, or auto-trim long chats while keeping only the latest N visible turns. Highlight feedback: the target message is emphasized after navigation. Native-looking UI: supports light, dark, and system theme modes. Local-only processing: no cloud sync, telemetry, or remote data upload. Supported platforms: ChatGPT, Gemini, Claude, and Doubao, with more platforms being added over time.
