Browser extension or app that uses facial recognition to remove posts about specific people from social feeds.

The pain

Users see unwanted content about people they want to avoid—ex-partners, annoying celebrities, polarizing figures—and current blocking tools only hide direct interactions, not mentions or photos.

The gap

Social platforms don't offer granular content filtering by person across all post types. Users manually scroll past or mute keywords, which is incomplete and exhausting.

Build angle

Start as a browser extension that intercepts feed content before render, identifies faces or names of blocked individuals, and hides those posts. Test demand with 500 beta users on one platform (Twitter/X) before expanding.

Strengths

  • Clear, specific user frustration with existing solutions
  • Technical feasibility as a third-party tool (no platform permission needed)
  • Low barrier to initial MVP—browser extension with basic image detection
  • Recurring use case: users will keep extension active long-term

Risks

  • Facial recognition accuracy will fail on low-quality images, causing frustration or false positives
  • Platforms may block or rate-limit third-party tools accessing feeds
  • Privacy concerns: storing user blocklists and processing images raises data handling questions
  • Niche audience: most users tolerate unwanted content or use existing mute/block features
  • Monetization unclear: hard to charge for a tool that solves a problem users accept as normal
  • Legal exposure: using facial recognition on public figures may trigger regulatory scrutiny
