# Smart Tool Matrix

## What this site is

- A first-party directory that organizes PDF, image, developer, website-inspection and entertainment-oriented traditional-culture tools.

## Processing and limitations

- Processing differs by collection. Many PDF, image and developer utilities are designed for browser-side execution; website inspection and AI-assisted experiences send requests to a service.
- Browser-side design is not an independent privacy or security audit. Verify the active tool before using confidential or regulated data.
- Website-inspection results are point-in-time automated observations, not ranking guarantees, penetration tests or compliance certifications.
- Divination outputs have no established scientific basis and must not be used for medical, legal, financial, safety or other high-stakes decisions.
