👋 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.

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.

✨ Features

🌌 Core (Gemini & AI Studio)

• 📂 Folder Organization: Organize chats into a two-level folder hierarchy with drag-and-drop support.
• Gemini: Supports Account Isolation Mode and Custom Folder Colors.
• 💡 Prompt Vault: Save and reuse prompts across Gemini, AI Studio, and custom websites.
• ☁️ Cloud Sync: Sync folders and prompts through Google Drive, or iCloud on Safari.
• 🗑️ Batch Delete: Bulk delete conversations.
• 📐 Formula Copy: One-click copy for LaTeX and MathML (Word) source codes.
• 🌦️ Visual Effects: Add seasonal ambience with snow, cinematic rain, or falling sakura petals from the settings panel.

✨ Gemini Exclusive

• 📍 Timeline Navigation: Visual nodes to jump between messages, star key moments, and manage conversation branches.
• 💾 Chat Export: Export conversations to JSON, Markdown, or PDF with images included.
• 🧜‍♀️ Mermaid Rendering: Auto-render flowcharts, sequence diagrams, and other Mermaid charts.
• 📝 Markdown Rendering Fix: Automatically fix broken bold syntax caused by Gemini's injected HTML elements.
• 🍌 Image Refinement: Lossless watermark removal for Gemini-generated images.
• 🔬 Deep Research: Extract thinking processes and research links from Deep Research sessions.
• 🛠️ Power Tools:
• Quote Reply: Reply with context by selecting text.
• Prevent Auto Scroll: Intercepts unwanted jumping behavior when hitting enter to send a new prompt.
• Input Collapse: Auto-expandable input area for more reading space.
• Default Model: Set your favorite model as default.
• Hide Recent Items: Hide "Recent" list in the sidebar to reduce distraction.

🔌 Claude & ChatGPT

Powered by the Voyager Plugin Engine, 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.

🧩 Any Site — Even Localhost

Add any site in the extension popup and the Prompt Manager follows you there, local apps included. Here it is inside DeepSeek Harness running on localhost:3080:

🎨 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.

📥 Installation

> ⚠️ Note: Prompt Manager is the only feature that supports Gemini for Enterprise.
