Adds folders, a timeline and export to Gemini, ChatGPT, Claude and other AI chat sites
The problem it solves
You know you asked an AI about this last month, but the answer is buried somewhere in a sidebar of hundreds of untitled chats.
For Daily AI chat usersGemini and ChatGPT usersStudents and researchers
- Before
- You scroll an endless chat list, copy answers into notes by hand and retype the same prompts.
- After
- Chats sit in nested folders, long threads get a clickable timeline, and a chat exports to Markdown, PDF, JSON or one long image.

Overview
Voyager is an open-source browser extension that adds organizing tools to the web versions of Gemini, AI Studio, ChatGPT, Claude, DeepSeek and Kimi. You can file chats into nested folders, jump through a long conversation on a timeline, export a chat as Markdown, PDF, JSON or an image, and keep a prompt library that works on any site. Folders and prompts can back up to your own Google Drive, or iCloud on Safari. It suits anyone who uses AI chat every day and loses track of past conversations.
It brings the same folders, timeline and prompt library to several AI chat sites, and backups go to your own cloud drive rather than a Voyager server.
Try these first
Start with the first one: it is a small task you can check easily.
- Create a folder called [project name] in the Gemini or ChatGPT sidebar and drag two past chats into it.First try
- Export a long Gemini chat as Markdown and open it in your notes app.
- Save a prompt you reuse to the prompt library with a tag, then insert it on another chat site.
- Turn on Cloud Sync with Google Drive so your folders and prompts appear on your other computer.uses Google Drive

Features
From the creator's documentation.
| Feature | What it does | Runs |
|---|---|---|
| Folders | Nested folders in the chat sidebar, up to three levels deep, on six AI chat sites | The chat page |
| Timeline | A marker for each message in a long chat; click to jump, long-press to star | The chat page |
| Export | Save a chat as Markdown, PDF, JSON or one long image | Your computer |
| Prompt library | Save, tag, search and insert your prompts on any website | Your browser |
| Plugins | Switch features on or off per site; plugins are plain JSON and cannot run scripts | Your browser |
| Cloud Sync | Back up folders, prompts and stars to your own Google Drive, or iCloud on Safari | Your cloud account |
Good to know
You use one or more AI chat sites every day and can no longer find older conversations. Voyager files chats into folders in the site's own sidebar, adds a timeline for long threads and exports a chat to a file you keep.
Limits
- Features differ by site: folders, timeline and export work right away on Gemini, while on ChatGPT, Claude, DeepSeek and Kimi several of them are a switch in the popup's plugin list, and some are not offered on every site.
- Voyager changes the chat page itself, so a site redesign can break a feature until its site file is updated. On Gemini for Enterprise only the prompt library runs.
