Trigger: When someone submits an n8n form (“🚀 AI Prompt Generator”).
- BaseQuestions (n8n Form): shows the next form page
- RelatedQuestionAI (Basic LLM Chain): sends a prompt to an LLM, with model: Google Gemini Chat Model; output parser: Structured Output Parser
- Merge: merges the data from its input branches
- SplitQuestions (Split Out): splits a list into separate items
- PromptGenerator (Basic LLM Chain): sends a prompt to an LLM, with model: Google Gemini Chat Model; output parser: Auto-fixing Output Parser
- LoopQuestions (Loop Over Items (Split in Batches)): loops over the items in batches
