Notion AI Assistant Generator n8n Workflow Template

n8n workflow template · 18 nodes · Notion

Notion AI Assistant Generator is a free n8n workflow template that starts when a chat message is received and works with Notion and Anthropic Claude. It has 18 nodes, 8 of them AI nodes (Auto-fixing Output Parser, Anthropic Chat Model, Structured Output Parser and AI Agent). The notes inside the workflow say: “Input a Notion database URL and get an AI Assistant chatbot workflow for it based on this template” To run it, you add your own credentials for Notion API.

How it works

The text below comes from the sticky notes inside the workflow. We removed links, code samples and anything that looks like a key or token.

Generate new workflow version for specific notion db schema

Input a Notion database URL and get an AI Assistant chatbot workflow for it based on this template

Project in notion

#1 Serve chat, get URL from user, pull new notion DB schema

Uses n8n Chat trigger. Notion node will fail if an invalid URL is used, or if n8n doesn't have access to it. Also attempts to strip non URL text input. Simplifies notion DB outputs for more efficient token usage in AI Agent.

#2 GenAI step

Takes 2 inputs: original workflow template and new Notion database details from #1

#3 Does the new workflow look right?

Checks for previously identified cases (e.g. LLM outputs placeholder for certain values) then does general LLM check on whether it looks like valid n8n workflow JSON.

#4 Respond to Chat trigger

Each response to the chat trigger is one run. Data of the last node that runs in the workflow is sent to chat trigger, like Return success to chat

Nodes in this workflow

The 18 nodes in file order (sticky notes excluded). Branches and connections determine execution order in n8n:

  1. Notion (Notion)
  2. Return success to chat (Edit Fields (Set))
  3. Auto-fixing Output Parser (Auto-fixing Output Parser)
  4. Anthropic Chat Model (Anthropic Chat Model)
  5. Set schema for eval (Edit Fields (Set))
  6. Return error to chat (Edit Fields (Set))
  7. Anthropic Chat Model1 (Anthropic Chat Model)
  8. standardize schema (Edit Fields (Set))
  9. Simplify properties object (Code)
  10. Structured Output Parser (Structured Output Parser)
  11. Set input data (Code)This allows different routes to input into our agent (e.g. the retry branch). In the AI Agent, we can use a relative $json reference for data, since it's always the same input schema going in.
  12. Set schem for rerun (Edit Fields (Set))
  13. Add feedback prompt (Edit Fields (Set))
  14. Check for WF JSON errors (Switch)Placeholder jsonBody in tool - this means the 'Search notion database' tool got [object Object] as it's value (happening ~25% of the time)
  15. Generate Workflow Agent (AI Agent)
  16. Anthropic Chat Model2 (Anthropic Chat Model)
  17. When chat message received (Chat Trigger)
  18. Valid n8n workflow JSON? (Text Classifier)
