## Review summary

Users report strong filtering of AI content on YouTube, social feeds, and search, with value from the free tier and an ad-blocker-like approach. Major downsides include a paid gate for basic features, uneven performance across sites, over-blocking of non-AI content about AI, and a cumbersome settings UI.

### Pros

- Substantial reduction of AI content across major sites (YouTube, Google, social feeds)
- Ad-blocker-like filtering model that feels familiar and easy to understand
- Free version provides meaningful filtering value without needing to upgrade

### Cons

- Paywall/subscription required for basic features, which many users view negatively
- Inconsistent/limited effectiveness across sites (AI content not blocked everywhere; e.g., YouTube summaries still appear, Google Docs blocking incomplete)
- Over-broad blocking that also removes legitimate non-AI content about AI due to broad keyword filters
- Settings are clunky or poorly organized, making configuration tedious
