N8n prompt ab test

N8n prompt ab test is an n8n automation template for comparing different prompt versions via a webhook trigger. Reach for it when you want to find out which prompt wording gets better results from a language model, when you need to systematically test prompt variations for an AI pipeline without running experiments by hand, or before locking in a prompt for production use. Trigger: webhook. Integrations: none listed. The workflow receives an incoming webhook request and routes it through different prompt variants, collecting responses for side-by-side comparison. Built on n8n, deployable on any self-hosted or cloud n8n instance. The direction is prompt A/B testing — not overall model benchmarking or hallucination monitoring (separate templates exist for those production-reliability patterns). A good fit for teams iterating on prompts for chatbots, AI agents, or text-processing pipelines. Not suitable when statistically rigorous evaluation is required — the template captures responses but does not compute metrics automatically.
