How LoreGuard works

Knowledge-grounded AI with multi-layer verification.

Why LoreGuard?

The problem with AI NPCs isn't intelligence. It's trust.

Grounded responses

Every NPC response is verified against your lore documents. Unverified claims are caught and removed before players see them.

Debug before shipping

See citations for every line of dialogue. Know exactly which documents informed each response before players see it.

Works your way

Cloud API for online games with per-request billing. Offline bundle for single-player with zero ongoing costs.

The pipeline

A multi-stage system designed to keep NPCs honest.
