Turn form submissions into scored, summarized CRM contacts with hot-lead alerts in under an hour.

An importable n8n workflow that takes a lead from your website form, has an LLM classify it as hot, warm, or cold with a two-sentence sales summary, and upserts the contact into HubSpot by email. Hot leads trigger a Slack message and an email to your team. If the CRM sync fails, an error branch alerts you and marks the execution failed, so leads don't vanish silently.

What's included:

ai-lead-capture-crm.workflow.json (18 nodes, ready to import)

README: prerequisites, import steps, credentials, field mapping table, curl test commands, and how to swap in another CRM

Input validation with a 400 response for bad submissions, fast 202 reply to the form

Fallback when the AI call fails (lead still saved, flagged for review)

Who it's for: freelancers, agencies, and small B2B teams running n8n who want AI lead triage without building it from scratch.

Requirements: n8n 1.x (self-hosted or Cloud); an OpenAI API key or any OpenAI-compatible endpoint; a HubSpot private app token (or another CRM with a REST API); Slack and/or SMTP for alerts. You pay your own API usage.

What it's not: a hosted service, a CRM, or a done-for-you setup. You import and configure it on your own n8n instance. Credentials are placeholders; no keys are included. Need it set up and customized for you? That's my separate "AI lead-capture agent wired into your CRM" service.
