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.

Node: GeminiWeb

Unified node for all Gemini operations.

Example Workflows

Text-to-Image Generation

[GeminiWeb (text_to_image)] → [Preview Image]

Image Editing with References

[Load Image 1] → image_1 ─┐
[Load Image 2] → image_2 ─┼→ [GeminiWeb (image_to_image)] → [Save Image]
[Load Image 3] → image_3 ─┘

Vision Chat

[Load Image] → image_1 → [GeminiWeb (chat)] → [Text Output]

Available Models

Model	Description
unspecified	Default model (uses Gemini's default)
gemini-3-pro	Pro model
gemini-3-thinking	Thinking model
gemini-3-flash	Fast model (default)

Troubleshooting

Issue	Solution
"Cookie expired"	Re-login to gemini.google.com and update cookies
"v20 App-Bound Encryption"	Use manual method (recommended) or run as Admin with Edge
"No browser cookies found"	Use manual or cookie_file method (recommended)
"Cookie file not found"	Create gemini_cookies.txt with your cookies
"No images generated"	Try adding "generate" to your prompt
Import errors	Run pip install -r requirements.txt
Region restrictions	Image generation may not be available in all regions
v20 not decrypting	Run as Admin + close Edge + PythonForWindows installed

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/).

⚠️ Do NOT share debug_response.txt — it may contain your location and other personal details from Google.
