Startup Idea Validator

Describe a startup idea. The app runs a full AI pipeline — market sizing, live competitor scan with web search tools, SWOT analysis, and a landing page draft. All streamed.

You will learn to:

• Design and implement a multi-stage LLM pipeline with distinct agent responsibilities
• Use LangChain agents with Tavily web search to do live competitor research
• Stream multiple independent pipeline stages to the frontend simultaneously over SSE
• Build a pipeline progress tracker that visualizes each stage's completion status
• Generate a complete, exportable business analysis report from a single text input
