Installation

Either install it or just run pre-build MultiVibeChat.exe :)

Prerequisites

Python 3.8 or higher
pip package manager

Setup

Clone this repository:

git clone https://github.com/mato200/MultiVibeChat.git
cd MultiVibeChat

Install required dependencies:

pip install PyQt6 PyQt6-WebEngine

Run the application:

python MVC3.py

Usage

Basic Operation

First Launch: The app will open with all four AI services loaded
Login: Click "Login Mode" to enable manual login mode, then sign in to each service. I recommend signing in 1st to google's Ai studio
Send Prompts: Type your prompt in the text box and press Ctrl+Enter or click "Send to All"
Compare Responses: View responses from all AIs simultaneously

Keyboard Shortcuts

Ctrl+Enter - Send prompt to all AIs
Ctrl+Scroll - Zoom in/out in any panel
Alt - Show URL bars
Ctrl+Shift+I - Open developer tools (right-click)

Profile Management

Creating Profiles:

Type a new profile name in the Profile dropdown
Click "Switch / Create"
A new window will open with the new (browser) profile

Switching Profiles:

Select an existing profile from the dropdown
Click "Switch / Create"

Profiles store separate authentication states, cookies, and settings.

Login Mode

The "Login Mode" toggle allows manual interaction with websites:

OFF (default): Prompts are automatically sent to all AIs
ON: Disables automatic prompt injection, allowing you to manually interact with login pages
idk if this is actually true lol, AI made a summary

Use Login Mode when:

Signing in for the first time
Handling two-factor authentication
Dealing with OAuth flows

Pop-up Authentication

When services use OAuth pop-up windows (like Grok's Google sign-in):

Click the sign-in button on the service
A pop-up window will appear
Complete the authentication (It asked me for 2FA confirm on my phone)
The pop-up will auto-close when done

Alternatively, use the "🔐 Sign in with Google" button (dont really..) for a dedicated sign-in window.

Technical Details

Browser Compatibility

This application uses QtWebEngine (Chromium-based) and includes:

Standard Chrome user agent
Modern HTTP headers (sec-ch-ua, Sec-Fetch-*)
JavaScript compatibility layers for Chrome APIs
Popup window handling

Profile Storage

Profiles are stored in Home directory: E.g. C:\Users\MyName.multi_vibe_chat_profile_default

.multi_vibe_chat_profile_default/
.multi_vibe_chat_profile_work/
.multi_vibe_chat_profile_personal/

Each profile contains:

Cookies and session data
Local storage
Cache
IndexedDB data

Configuration

Last used profile is stored in .multi_vibe_chat_config.json

Troubleshooting

"This browser is not supported" errors

Some services may show browser compatibility warnings. Try:

Enable "Login Mode" and sign in manually
Use the dedicated sign-in dialog
Update your PyQt6-WebEngine to the latest version

Sessions not persisting

Ensure the profile directories have write permissions:

chmod -R 755 .multi_vibe_chat_profile_*

Pop-ups not working

If OAuth popups don't open:

Check that JavaScript is enabled (it should be by default)
Try using the manual "🔐 Sign in with Google" button
Use Login Mode and complete authentication in the main panel
