I Built an Open-Source Toolkit for AI Watermark & Provenance Forensics

Description and use

ClaudeMark is a local, open-source toolkit for AI watermark and provenance forensics that aggregates statistical signals, invisible Unicode analysis, metadata inspection, security auditing, and sanitization, enabling developers to analyze AI-generated content locally.

Problem

Investigating AI-generated content for provenance, metadata, and hidden signals without sending files to external services.

Outcome

ClaudeMark enables developers to locally inspect AI-generated artifacts, identify forensic signals, audit security, and sanitize metadata while keeping data on the machine.

Workflow

• 1. Install ClaudeMark from GitHub.
• 2. Run the CLI or API to input files or content.
• 3. The detection pipeline analyzes AI signals, Unicode characters, and metadata/provenance layers.
• 4. Review forensic results and optional security audit findings.
• 5. Optionally sanitize selected metadata artifacts before further use.

Evidence

ClaudeMark is an open-source, local-first toolkit for AI watermark and provenance forensics.
