What this workflow does
This AI workflow has 21 nodes and runs when someone submits an n8n form (plus 1 other trigger). Along the way it connects Ghost and OpenAI Chat Model.
How it runs
Trigger: When someone submits an n8n form (plus 1 other trigger).
- Research Leader 🔬 (AI Agent): runs an AI agent, with model: OpenAI Chat Model; 1 tool (Perplexity_tool)
- Perplexity API (HTTP Request): calls an HTTP API
- Project Planner (AI Agent): runs an AI agent, with model: OpenAI Chat Model; 1 tool (Perplexity_tool); output parser: Structured Output Parser
- Response (Edit Fields (Set)): sets or maps fields
- Delegate to Research Assistants (Split Out): splits a list into separate items
- Merge: merges the data from its input branches
- Research Assistant (AI Agent): runs an AI agent, with model: OpenAI Chat Model; 1 tool (Perplexity_tool)
- Final article text (Code): runs custom JavaScript code
- Editor (AI Agent): runs an AI agent, with model: OpenAI Chat Model
- Create title (Basic LLM Chain): sends a prompt to an LLM, with model: OpenAI Chat Model
…plus 1 more step. See the full node list below.
Services it uses
Before you upgrade to n8n 3.0
1 thing in this workflow is removed in n8n 3.0. Fix it before you upgrade:
- AI Agent v1 (old agent modes) in Research Leader 🔬 (v1.6), Research Assistant (v1.6), Project Planner (v1.7)…: replace with Latest AI Agent node (Tools Agent). For SQL Agent, use a Postgres or MySQL tool with a recent AI Agent.
