Trigger: When a chat message arrives (plus 1 other trigger).
- Load Fingerprint List (Data table): get
- Check Existing Words (Data table): get
- Extract Stylometric Metrics (Code): runs custom JavaScript code
- Format Existing List (Code): runs custom JavaScript code
- Agent Orchestrator (Chat): uses Chat
- Find New Words (Basic LLM Chain): sends a prompt to an LLM, with model: LLM - Generator
- Agent 1 - The Scanner (AI Agent): runs an AI agent, with model: LLM Scanner
- Split into Rows (Code): runs custom JavaScript code
- Package Scanner Output (Code): runs custom JavaScript code
- Save New Fingerprints (Data table): uses Data table
…plus 6 more steps. See the full node list below.
Services it uses
Before you upgrade to n8n 3.0
