Real-time content moderation

Our Library AI Hub includes automatic content moderation on every message — patrons don't see it happening, but it's always on.

Every message, checked before it reaches the AI

Each patron message is checked against a content moderation service before it's sent to the AI. Messages that flag as potentially harmful (violent, sexually explicit, harassing, or otherwise policy-violating) end the session immediately. Moderation is nearly instantaneous, so it doesn't interfere with normal activity.

What the patron sees

An amber alert bar appears with the message: "This session has ended. A librarian can help you find resources on this topic." The input is disabled and a "Start New Chat" button appears so they can begin a new (clean) session.

No error code, no harsh language, no indication of what triggered the block — just a friendly nudge toward a librarian.

What library administrators see

Moderation events are logged and visible in the Analytics admin screen under "Moderation Events." You'll see counts by category (e.g., "harassment," "violence") — never the actual message content. This helps ensure patron privacy no matter the topic at hand.

Aggregate counts give you the visibility you need to spot patterns or report to your board, without ever exposing what an individual patron typed.
