Welcome to Custodian Labs
Custodian Labs helps you build AI applications that work safely with sensitive data. Use the Python SDK to create AI assistants, and use Guardian Layer to protect sensitive information before it reaches an LLM or another downstream system.
What can you build?
AI assistants with the Python SDK
Build and deploy conversational AI assistants in Python. Add instructions, examples, and knowledge files, use retrieval-augmented generation (RAG), and support multi-turn chat sessions.
Privacy-safe workflows with Guardian Layer
Detect and de-identify sensitive information in text and files. Guardian Layer gives you several ways to handle detected information:
- Transform sensitive content into safer alternatives while preserving useful context.
- Redact sensitive content when it should be removed.
- Mask detected values for straightforward de-identification.
- Use placeholders when protected values need to remain identifiable by category.
Use Guardian Layer as a standalone API or as part of an AI workflow.
Account and API management in the Dashboard
