- Character Image (Extract from File): extracts data from a file (binary to propery)
- Setting Image (Extract from File): extracts data from a file (binary to propery)
- Merge: merges the data from its input branches
- Upload Images (Base64→URL) (HTTP Request): calls an HTTP API (POST)
- Aggregate: combines items into one
- Generate Post Ideas (AI Agent): runs an AI agent, with model: LLM (OpenAI Chat Model); 1 tool (Think); output parser: Structured Output Parser
- Split Posts (Split Out): splits a list into separate items
- Create Image Task (Execute Sub-workflow): calls another n8n workflow
- Append row in sheet (Google Sheets): append
