Things to check
- No licence is stated, so reuse rights are unclear
- Can be used for privacy invasion or stalking; the author says it is for educational use and only with permission
- The AI feature needs an API key from the developer's service and has a daily limit
- Relies on checking many third-party sites, which may breach some sites' terms and can give out-of-date results
