AI Evaluation: String Similarity for Handwritten Code Extraction

This n8n workflow template demonstrates the evaluation feature for AI-powered automations. It processes images of handwritten codes, uses AI (likely a vision model) to extract the text, and calculates a character-by-character string similarity score against expected values from a test dataset. The evaluation trigger runs alongside a regular trigger, allowing seamless testing without altering production flows. Key benefits include gaining confidence in AI reliability by quantifying performance m
