## What is "Is This Link Safe?"

"Is This Link Safe?" is a browser extension that helps you instantly verify if a link is safe before you click. It detects phishing attempts, scams, and dangerous URLs using an advanced heuristic engine.

## Core Features

- **Advanced Detection**: Get immediate feedback on any link's safety. Our engine checks for patterns used by scammers (typosquatting, suspicious parameters, known patterns).
- **Smart Analytics**: We analyze browsing patterns to improve security and build detailed statistics to help you understand your online footprint.

## How it Works

The extension analyzes URLs for common risk indicators:
1. **Typosquatting**: Detects domains that look similar to popular brands (e.g., `paypa1.com` instead of `paypal.com`).
2. **Suspicious Patterns**: Identifies unusual URL structures, long random paths, and use of IP addresses.
3. **Keyword Analysis**: Checks for sensitive keywords (login, verify, update) in unrelated domains.
