# Access and visibility

Access and visibility define which knowledge sources a user, application, or workflow can see and use.

This matters for the [AI Knowledge Base](/about/platform/ai-knowledge-base.md) because governed retrieval should only use sources that are in scope for the requesting context.

## What visibility protects

Visibility protects against AI responses that are grounded in the wrong information. A source that is outside the allowed boundary should not appear in retrieval results or be used as context for a response.
