Generate PII-Safe Helpdocs from Crisp Support Chats with GPT-4.1-mini

Turn Crisp chats into Helpdocs

Automatically create help articles from resolved Crisp chats. This n8n workflow listens for chat events, formats Q&A pairs, and uses an LLM to generate a PII‑safe helpdoc saved to a Data Table.

Highlights

🧩 Trigger: Crisp Webhook when a chat is marked resolved. 🗂️ Store: Each message saved in a Data Table (crisp). 🧠 Generate: LLM turns Q&A into draft helpdoc. 💾 Save: Draft stored in another Data Table (crisphelp) for review.

How it works

Webhook receives message:send, message:received, and state:resolved events from Crisp. Data Table stores messages by session_id. On state:resolved, workflow fetches the full chat thread. Code node formats messages into Q: and A: pairs. LLM (OpenAI gpt-4.1-mini) creates a redacted helpdoc. Data Table crisphelp saves the generated doc with publish = false.

Requirements

Crisp workspace with webhook access (Settings → Advanced → Webhooks) n8n instance with Data Tables and OpenAI credentials

Customize

Swap the model in the LLM node. Add a Slack or Email node after store-doc to alert reviewers. Extend prompt rules to strengthen PII redaction.

Tips

Ensure Crisp webhook URL is public. Check IF condition: {{$json.body.data.content.namespace}} == "state:resolved". Use the publish flag to control auto‑publishing.
