Tools to try this autumn: 7 developer tools, privacy auditors, and AI skills

This edition features seven software tools and utilities for developers, engineers, and privacy-conscious users. The selections cover visual effects generation, local note-taking, system privacy auditing, and interactive 3D modeling.

Every item on this list was gathered from recent activity across GitHub, Hacker News, and Product Hunt. We select open-source projects, AI skills, and practical utilities based on functionality.
