About This Workflow
Unlock efficient vehicle data processing with this advanced n8n workflow. It uses a user-friendly web form to accept image uploads (JPG/PNG). Behind the scenes, the workflow harnesses cutting-edge multimodal AI, specifically integrating with openai/gpt-4o via OpenRouter, to intelligently analyze the image. It precisely identifies the front-most vehicle's license plate and extracts only the alphanumeric characters. This automation reduces human error, accelerates data capture for various operational needs, and provides a clear, concise result directly back to the user.
