Many users get frustrated hitting paywalls when searching for information. A tool could integrate with search engines to filter or flag paywalled links upfront.
Build a browser extension or standalone search interface that checks for paywall patterns (like medium.com/membership, nytimes.com/subscribe) and either removes them or adds a warning icon.
Freemium model: free tier filters basic sites, paid tier handles custom patterns or niche publications.
MVP: a Chrome extension with hard-coded detection for top 20 paywall sites.
Risk: Search engines could block scraping or change markup to break detection.
