About
Noirdoc is a German-language AI chat and API proxy service that pseudonymizes sensitive input before it reaches an LLM. It detects and replaces personal data, company names, locations, tax IDs, URLs, IBANs, email addresses, and phone numbers with placeholders such as <> and restores the original values in the response after model execution.
The hosted chat plan includes 10 messages per day on the free tier, one model (Sonnet 4.6), and no account requirement. The pricing page also describes an API Proxy product for developers, with text pseudonymization, rule-based and context-sensitive detection, streaming support, session-consistent placeholders, and support for OpenAI, Anthropic, Azure OpenAI, OpenRouter, and any OpenAI-compatible endpoint.
