Gemini Voyager

A Chrome extension that adds a silky, interactive timeline to your Gemini chats.

中文说明

Intro

Gemini Voyager transforms your experience on https://gemini.google.com/app by adding a refined, interactive timeline—mirroring the intuitive flow found in AI Studio:

Timeline

• Your messages are mapped to nodes; click to jump or flow to the message.
• Hover to preview the prompt (3‑line clamp with gradient fade).
• Long‑press to star a node; stars sync across tabs.
• Robust SPA observers keep the active state in sync while you scroll.

Prompt Manager

• Save and reuse prompts with tags; instant search and one‑click copy
• Import/export your prompts as JSON
• Compact floating panel anchored to the trigger with optional lock; works on Gemini and AI Studio

Export Chat History

• Click the small export icon next to the Gemini logo to download the current page's chat as JSON.
• The exported file uses the format gemini-voyager.chat.v1 and includes:
• url, exportedAt, count
• items: ordered pairs of { user, assistant, starred }
  • starred mirrors your timeline stars for each user turn
  • The assistant text excludes the on-page reasoning toggle labels (e.g., "Show thinking", "显示思路")

Example payload shape:

{
  "format": "gemini-voyager.chat.v1",
  "url": "https://gemini.google.com/app/...",
  "exportedAt": "2025-01-01T12:34:56.000Z",
  "count": 3,
  "items": [
    { "user": "...", "assistant": "...", "starred": true }
  ]
}
