A developer describes using Meta's Muse AI assistant for large-scale web scraping to build fullsets.fm, a concert aggregation project. While finding the personal assistant features less useful, they praise Muse's ability to efficiently scan Reddit and YouTube for videos, handle data processing via integrated AI models, and manage automated browser tasks at scale for $80/month. The author raises concerns about potential abuse if similar tools target e-commerce sites, noting Amazon has already blocked it.
