This n8n workflow automates the process of discovering startup ideas by analyzing Reddit posts across several niche communities. When triggered manually, it searches Reddit for posts with specific keywords such as ‘Why is there no tool that’ in communities focused on innovative ideas and side projects. The workflow retrieves these posts, extracts relevant details, and processes the content through an AI engine (Google Gemini) to analyze the core problems, identify existing solutions, and generate new startup ideas. It also allows for data to be appended to a Google Sheet for record-keeping or further review. This workflow is ideal for entrepreneurs and innovation teams aiming to stay updated with emerging problems and unmet needs from active online communities.
