What you get
An n8n workflow that serves a hosted form and turns each submission into a short AI summary using the Basic LLM Chain node.
Prerequisites
- An n8n Cloud or self-hosted instance
- A chat model credential (for example OpenAI or Anthropic), or Gateway credits on n8n Cloud
Steps
- Create a new workflow and add the n8n Form trigger. Set Authentication to None, give the form a title, and add two fields labelled
Name and Message.
- Click + after the trigger and add Basic LLM Chain.
- Set Prompt to Define below and paste this into Prompt (User Message):
Summarise this form submission in 2 sentences and label its intent as one of: question, bug, sales, other.
Name: {{ $json.Name }}
Message: {{ $json.Message }}
- Under Chat Messages, add a System message:
You are a concise support triage assistant.
- Click the Model connector under the chain, add a chat model sub-node (for example OpenAI Chat Model), and pick your credential and model.
- Optional: add a Slack, Gmail or Google Sheets node after the chain and map the chain's
text output.
Test it
Click Execute Workflow. n8n opens the form on its Test URL; submit a message and check the chain output in the editor. When it looks right, use the Production URL and publish the workflow.
