n8n AI Form Workflow: Qualify Leads with Google Gemini

Turn website form questions into qualified leads—instantly—with n8n + Google Gemini

This n8n AI Form Workflow captures visitor inquiries from a public n8n form, uses Google Gemini to generate a concise sales response and product recommendations, then saves every submission as a lead in an n8n Data Table—before replying back to the visitor.

What this workflow does

• Collects inquiry details via an n8n website form (name, email, company, and the visitor’s question).
• Answers with an AI agent powered by Google Gemini (PaLM), using a sales-guided system message to respond to the product question.
• Parses structured output into an answer plus a recommended_products list.
• Stores lead data in an n8n Data Table: visitor details, the AI answer, the recommended products, and a submission timestamp.
• Returns the result to the visitor as the form completion response, showing the AI answer and recommendations.

Use cases

• A SaaS site can qualify inbound product questions and automatically respond with relevant items while capturing leads for follow-up.
• An automation engineer can deploy an AI-assisted sales intake form that logs every inquiry for reporting and nurturing.
• An n8n operator can maintain better conversion by combining immediate AI answers with persisted CRM-like lead records.
