GripeFind is an AI-powered research tool for founders who want to build products people actually need. Type any niche and it runs live searches across Reddit, Hacker News, and independent forums, then uses Claude AI to extract real complaints and score each one as a business opportunity across five dimensions: demand, competition, passive-income potential, feasibility, and monetization.
What you get:
GripeFind searches the open web through a search index rather than Reddit's commercial API, the dependency that shut down GummySearch. Free plan includes 3 research queries to start (then 1/month), no card required. Pro is $29/month for 50 queries and standing alerts.
