n8n Workshop: How to use AI Evals: with Dr. Pure Eval

​This session is part of the n8n Community Challenge, a monthly build-and-learn experience for builders, tinkerers, and curious minds of all levels.

​This month's challenge: build an AI agent in n8n that classifies and responds to inbound emails for Nexus Integrations, then prove it works using n8n's AI evaluation features. Deadline is March 22.

​The evals part is where most people get stuck. That's what this session is for.

​Marcel Claus-Ahrens, better known in the community as Dr. Pure Eval, is joining us live on Thursday March 19 at 7PM CET to answer your questions. Bring your half-finished workflow, bring your confusion, and leave with a clear path to submitting.

​Topics we'll cover:

• ​Why evaluations matter and what breaks without them

• ​How n8n's eval framework is structured

• ​How to add an Evaluation Trigger to your workflow

• ​How scoring works: what gets a 1, what gets a 0, and why wrong classification cascades into a wrong reply

​Who this is for:
Anyone working on this month's challenge. You don't need to be an expert. If you've started building and have questions, this session is for you.

​After the session:
Submit your workflow at n8n.io/community-challenge before March 22. Post with #n8nChallenge for a chance to win official n8n merch.

Top submissions get featured in the Community Livestream on March 26, which will take place via our Youtube Channel.
