USE CASE 1

Organise hundreds of Gemini chats into two-level folders with drag-and-drop so important conversations stop getting buried.

USE CASE 2

Save reusable prompts in a personal vault and deploy them across Gemini, AI Studio, and custom websites in one click.

USE CASE 3

Export a full chat as Markdown, JSON, or PDF with images to archive research or share with your team.

USE CASE 4

Use the conversation timeline to jump back to any starred message in a long Deep Research session.

In plain English

Gemini Voyager is a browser extension that adds power-user features to Google's Gemini chatbot and Google AI Studio. You install it once and the next time you open Gemini, the page gains new sidebars, buttons, and menus that let you organise, save, and export your AI conversations in ways the built-in interface does not support. The headline features are a folder system for grouping chats into a two-level hierarchy with drag-and-drop, a prompt vault for saving and reusing prompts across Gemini, AI Studio, and custom websites, cloud sync of folders and prompts to Google Drive, and a timeline that turns a long conversation into clickable nodes so you can jump back to specific messages or starred moments. It can export a chat as JSON, Markdown, or PDF (with images), render Mermaid diagrams, fix broken bold formatting that Gemini sometimes produces, copy LaTeX or MathML formulas in one click, and pull thinking traces and links out of Deep Research sessions. Smaller tools include batch deletion, quote-reply on selected text, syncing the browser tab title to the chat title, default-model selection, and a lossless watermark-remover called NanoBanana for Gemini-generated images. You would install it if you use Gemini or AI Studio heavily, for research, code, or content work, and have hit the limits of the default interface, especially around keeping conversations findable. The extension is written in TypeScript, built with the Bun JavaScript runtime, and distributed for Chrome, Edge, Firefox, Safari, Opera, and Brave. The README is translated into nine other languages. The full README is longer than what was provided.
