## 👋 Why Voyager?

We love AI chatbots, but sometimes we wish they had just a _bit_ more structure.

That's why I built **Voyager**. It's a companion that helps you keep your AI conversations organized, accessible, and productive — whether you're on Gemini, Claude, or ChatGPT. If you're a researcher juggling dozens of threads, a developer saving code snippets, or just someone who loves order, Voyager is designed for you.

  <i>During the issue on February 18th where the Google Gemini App caused some users' historical conversations to become inaccessible, Voyager users were still able to see their saved conversations in their folders.</i>

  - **[Hide Recent Items](https://voyager.nagi.fun/en/guide/recents-hider)**: Hide "Recent" list in the sidebar to reduce distraction.

### 🔌 Claude & ChatGPT

Powered by the [Voyager Plugin Engine](https://voyager.nagi.fun/en/plugins), these features extend your experience beyond Gemini:

- **📍 Claude Timeline**: Conversation sidebar with starred messages and search — the same navigation flow, now on Claude.
- **📊 Claude Usage Bar**: Track your session and weekly usage directly in the Claude interface.
- **📐 Formula Copy**: One-click copy for LaTeX and MathML source codes (shared with Gemini).
- **📖 Comfortable Reading Width**: Adjust chat width for a better reading experience on Claude and ChatGPT.
- **🈶 CJK Render Fix**: Fix CJK character rendering issues on Claude.

### 🎨 Personalization

- Open the extension popup and find **Visual Effects** to switch between `Off`, `Snow`, `Sakura`, and `Rain`.
- Effects are rendered as lightweight full-screen overlays and do not block page interaction.
- When you switch effects or turn them off, existing particles drain out naturally instead of disappearing abruptly.
