Show HN: StopX – AI-powered content blocker with 99.7%
6 popwatch 3 6/11/2025, 7:15:21 AM stopx.today ↗
Built StopX after struggling with the limitations of traditional blocklist-based filters. Most existing solutions rely on static URL databases that are constantly outdated and easily bypassed.
Our approach uses proprietary WebShield™ technology that combines:
Real-time AI image recognition for visual content analysis
Contextual URL pattern matching beyond simple domain blocking
Cross-device synchronization with encrypted settings sync
Military-grade bypass protection with stealth mode operation
The interesting technical challenge was achieving 99.7% accuracy while maintaining sub-100ms response times. We solved this with a lightweight edge model that preprocesses content before it reaches the browser, combined with cloud-based deep analysis for edge cases.
Currently supporting Chrome, Firefox, iOS, Android, Windows, and Mac with seamless cross-platform experience. The system has processed over 50M requests with 250K+ active users.
Technical deep-dive and API documentation available. Happy to discuss the computer vision and real-time filtering challenges we solved.

Neat; I built a child internet filter using a similar idea, although we routed the child's internet through a VPN, and were a little more active about reading page content and filtering that part of the page. It was never a big sell for parents, but hopefully you can be more successful in this market!

it's funny when you imagine that now we're using AI ad-blockers to block AI generated content

The nofap bullshit is back with AI and subscriptions. At least you found a niche to scam anxious people. Good work!
