PII guard for Claude Code to keep client data out of context
noirdoc is an open-source plugin designed to enhance data privacy when working with large language models (LLMs) like Claude. It acts as a PII guard, automatically redacting sensitive information such as names, emails, and IBANs before the data is processed by the LLM. This ensures that client data remains confidential and out of context, while still allowing users to reveal original information locally when needed. Available as a CLI for any LLM and as a hosted proxy for platforms like OpenAI, Anthropic, and Azure, noirdoc offers flexible deployment options tailored to developers and privacy-conscious teams. Its unique approach of local redaction and de-redaction strikes a balance between data security and usability, making it particularly appealing for industries handling sensitive customer data.
Pros
- Open-source, allowing for customization and transparency
- Flexible deployment options: CLI and hosted proxy
- Effective PII redaction that maintains data privacy
- Supports multiple LLM platforms (OpenAI, Anthropic, Azure)
- Easy to integrate into existing workflows
Cons
- Requires technical expertise to set up and customize
- May need ongoing maintenance for updates and improvements
- Limited user interface, primarily command-line based
Best for
- • Redacting sensitive customer data before using LLMs in customer support
- • Ensuring compliance with data privacy regulations during data processing
- • Preprocessing data in AI research projects involving personal information
- • Securely sharing data with third-party AI services
Pricing: Being open-source, noirdoc is free to use and modify. Additional costs may arise from hosting or infrastructure depending on deployment choices, but the core tool itself does not have a subscription fee.
