| What makes it different | - Files never leave your device - all inspection runs locally in your browser
- Independent tool not affiliated with or endorsed by the Coalition for Content Provenance and Authenticity
- Reports evidence not verdicts - no authenticity percentages or false claims
- Multiple inspection views for different user needs and expertise levels
- Privacy-focused with non-sensitive usage metrics only via Google Analytics
| - Library remains separate from active setup, delivering only relevant skills to each tool or project
- Source attachment remembers GitHub or GitLab origin so you can compare versions before updating
- Security findings and approvals tied to exact version reviewed, not carried forward automatically
- Shared team skills do not override individual personal libraries
- Works with existing tools without requiring abandonment of Cursor, Claude Code or repositories
