PainSpotter - Mine real user pain from across the web, scored by AI

PainSpotter reads thousands of real conversations across the web every day, then uses LLMs to score each pain point by intensity, payment willingness, and technical feasibility. Get a ranked feed of validated SaaS opportunities — plus daily AI analyses and weekly theme reports. Free tier + REST API & MCP. Built for indie hackers and AI agents tired of guessing what to build next.
