Monity acts as an autonomous pair of eyes on the internet. It monitors websites that don't have APIs, tracking visual and structural changes in real-time.
### Why it's a Niche Powerhouse
* **Visual Diffing**: It shows you a side-by-side comparison of exactly what changed on a page (e.g., a competitor changing their "Pro Plan" price).
* **Regulatory Alerts**: Lawyers use it to monitor government portals for new judgments or policy updates that haven't been publicized yet.
* **Data Extraction**: When a change is detected, it can automatically extract the new data into a CSV or push it to a Slack channel via webhook.
**Best for**: E-commerce brands and market researchers who need to stay ahead of "silent" web updates.
