ChatGPT Ether

Language: English | 中文

ChatGPT Ether is a Chrome extension for personal ChatGPT conversation management.

It is not a chatbot and does not replace ChatGPT. The goal is to add a lightweight personal workspace on top of the ChatGPT web app: manage prompts, organize conversations, star important messages, view the current conversation timeline, and optionally sync safe metadata to your own Google Drive.

Current version: v1.0 beta. This is a public beta release intended for personal workflow testing.

What It Does Not Do

ChatGPT Ether intentionally keeps a narrow boundary:

• Does not call ChatGPT private APIs
• Does not read cookies
• Does not read browsing history
• Does not request all_urls
• Does not upload full chat transcripts
• Does not sync full chat transcripts
• Does not automatically scan all historical conversations
• Does not delete or hide ChatGPT native conversations
• Does not pretend to be an official OpenAI product

Installation: Download the Release Package

ChatGPT Ether is not currently published on the Chrome Web Store. The recommended installation method is to download the Chrome extension package from GitHub Releases and load it as an unpacked extension.

1. Open the Releases page
2. Download the latest Chrome extension zip package
3. Unzip the package
4. Open chrome://extensions/
5. Enable Developer mode
6. Click "Load unpacked"
7. Select the extracted extension folder

Build from Source

If you prefer to build the extension yourself, use the steps below.

1. Clone the Repository

git clone https://github.com/dowevip/chatgpt-ether.git
cd chatgpt-ether

2. Install Dependencies

If Bun is installed globally:

bun install

If Bun is not installed globally:

npx --yes bun@latest install

3. Build the Chrome Extension

bun run build:chrome

Or:

npm run build:chrome

The build output is:

dist_chrome

4. Load in Chrome

1. Open chrome://extensions/
2. Enable Developer mode
3. Click "Load unpacked"
4. Select the dist_chrome directory

Update

If you installed from a Release package, download the newer package, unzip it, and reload the new folder in chrome://extensions/.

If you built from source:

git pull origin main
npm run build:chrome

Then open chrome://extensions/ and click "Reload" on the ChatGPT Ether extension card.

Google Drive Sync

Google Drive sync is currently manual.

Data that may be synced:

• Prompt Vault data
• Folder structure
• Conversation index
• Conversation notes
• Starred-message metadata
• Extension settings
• Necessary time metadata

Data that is not synced:

• Full chat transcripts
• Full assistant replies
• Attachments
• Images
• Canvas content
• Screenshots
• Large raw conversation JSON

The sync file is stored in your own Google Drive appDataFolder, which normally does not appear in the regular Drive file list.

Privacy

ChatGPT Ether reads the necessary structure of the currently opened ChatGPT page to build the timeline, search the current conversation, locate messages, and show diagnostics.

Extension data is stored locally by default. Only when you explicitly use Google Drive sync will the allowed sync data be uploaded to your own Google Drive.

The extension does not sell user data, does not upload full chat transcripts to third-party services, and does not read cookies or browsing history.
