Creators post blindly, not knowing which elements (captions, hooks, tags) actually convert viewers to followers. A tool could analyze metadata and viewer paths to reveal what works.
Offer heatmaps showing where viewers drop off or follow, plus A/B testing for captions. Charge per detailed reports.
Start by scraping public data for micro-influencers, then add API integrations for paying clients.
The risk is Instagram restricting data access or copying features.
