Description

This workflow contains community nodes that are only compatible with the self-hosted version of n8n.

Workflow Description: Startup Idea Finder (n8n)

What This Workflow Does:

This n8n workflow helps entrepreneurs discover startup ideas by automatically scraping top posts from multiple subreddits that often discuss unmet needs or problems (e.g., posts containing phrases like โ€œWhy is there no tool thatโ€, โ€œI wish there was an app forโ€, โ€œsomeone should makeโ€, etc.). The workflow extracts key information from these posts and sends it to Googleโ€™s Gemini 1.5 Flash-8b AI model, which analyzes the problem and suggests possible solutions or startup ideas. All relevant data and AI-generated insights are then saved to a Google Sheet for easy review and tracking.

AI Analysis: The filtered post data is sent to the Gemini 1.5 Flash-8b model with a prompt asking for:

5. Google Sheets Logging: Both the original post data and the AIโ€™s output are appended as a new row in a Google Sheet for future reference.
