Stop guessing which prompt wording performs best. This n8n workflow runs controlled A/B tests on your OpenAI prompts, sending variants through the model and logging each result to Supabase so you can compare quality, tone, and consistency on real data. It helps builders and prompt engineers pick winning prompts based on evidence instead of gut feel.
