Installation

1. Clone or Download

cd ComfyUI/custom_nodes
git clone https://github.com/Koko-boya/Comfyui-GeminiWeb.git

Or download and extract to ComfyUI/custom_nodes/Comfyui-GeminiWeb

2. Install Dependencies

cd Comfyui-GeminiWeb
pip install -r requirements.txt

3. Restart ComfyUI

Authentication Setup

Modern Chrome/Edge (v127+) uses App-Bound Encryption (v20) which requires special handling.

Option 1: Manual (Recommended)

The simplest and most reliable method:

1. Login to gemini.google.com
2. Press F12 → Application → Cookies → gemini.google.com
3. Copy __Secure-1PSID and __Secure-1PSIDTS values
4. Paste directly into the node's cookie inputs

Option 2: Cookie File

Store cookies in a file for reuse:

1. Edit gemini_cookies.txt in the node folder: __Secure-1PSID=your_value_here __Secure-1PSIDTS=your_value_here
2. Use "cookie_file" in the node

Option 3: Auto Cookies (Run as Administrator)

For automatic v20 cookie decryption (Edge only tested):

1. Run ComfyUI as Administrator
2. Login to gemini.google.com in Edge
3. Close the browser completely (important!)
4. Make sure the browser is not running in the background
5. Check Task Manager and end any Edge/Chrome processes
6. Use "auto_cookies" in the node

Why Admin? Chrome/Edge 127+ use App-Bound Encryption (v20) which requires SYSTEM-level access to decrypt. Currently only Edge is tested.

Reporting Issues

If you encounter problems, please open an issue with the prompt you used, or enable debug_mode in the node and attach the debug_request.txt file (found in the node's directory under custom_nodes/Comfyui-GeminiWeb/).
