This benchmarks Instagram posts and Reels to spot what's working in your niche. Feed it usernames, post URLs, or hashtags and it pulls 10-15 examples per theme, ranks them by engagement and relevance, then extracts the hooks, caption patterns, and formats you can reuse. The workflow keeps the first pass small so you're not drowning in content before you know if the seed was any good. It's designed to hand off cleanly to other skills when you need creator outreach or audience voice analysis. Worth using when you need content patterns, not when you already know which accounts to study.
