What is NoirDoc?
NoirDoc is a PII (Personally Identifiable Information) guard built specifically for Claude Code, designed to prevent sensitive client data from ever reaching the AI's context window. It acts as a privacy layer between your codebase or documents and the Claude Code environment, automatically detecting and filtering out names, emails, financial data, health records, and other regulated information. For any developer or team working with real client data, NoirDoc provides a critical compliance and confidentiality safeguard without disrupting their existing workflow.
Key Features
- Automatic PII Detection: Scans documents and code files in real time to identify sensitive data including names, addresses, phone numbers, social security numbers, and financial identifiers before they are passed to Claude Code.
- Context Window Sanitization: Strips or masks PII at the point of ingestion, ensuring the AI model never processes raw sensitive data, which helps teams stay compliant with GDPR, HIPAA, and CCPA requirements.
- Seamless Claude Code Integration: Works as a guard layer that sits between the developer's local environment and Claude Code, requiring minimal setup and no major changes to existing development workflows.
- Redaction Logging: Maintains a log of what was detected and redacted, giving team leads and compliance officers a transparent audit trail for data handling practices.
- Customizable PII Rules: Allows teams to define custom sensitive data patterns relevant to their specific industry or client contracts, going beyond standard PII categories.
Real-World Workflow Example
A freelance developer working on a healthcare client's billing system pastes a chunk of patient records into their Claude Code session to debug a parsing error. NoirDoc intercepts the data first, automatically redacting patient names, dates of birth, and insurance IDs before the content reaches Claude Code's context. Claude Code still receives enough structural information to help debug the logic. Result: The developer gets accurate AI assistance without ever exposing protected health information to a third-party model ā keeping the project HIPAA-compliant and the client relationship intact.
Pricing
NoirDoc is an early-stage tool launched via Product Hunt, and as is typical for tools at this stage, it most likely offers a free tier for individual developers to test core PII filtering functionality. Paid plans are expected to unlock team collaboration features, advanced custom rule sets, compliance reporting dashboards, and higher volume processing. Enterprise pricing with dedicated support and deeper integrations is likely available on request. Given the compliance-critical nature of the tool, paid plans likely start around $15ā$49 per month for small teams, scaling upward for larger organizations.
Who Should Use This?
NoirDoc is essential for freelance developers and agencies who handle client data and want to responsibly use AI coding assistants without violating NDAs or data protection agreements. It is equally valuable for in-house engineering teams at companies operating in regulated industries such as healthcare, legal, fintech, and HR tech. Compliance officers and CTOs who want to enable AI-assisted development without opening the company up to data privacy liability will find NoirDoc a practical and necessary tool in their stack.

Final Verdict
NoirDoc addresses one of the most quietly pressing problems in the AI-assisted development space: the accidental exposure of sensitive client data to large language models.
