Moonborn.
Character Consistency Engine

Keep AI characters the same person, even after the 100th message.

Moonborn keeps AI characters from losing their tone, behavior, and personality across long conversations, channels, and languages.

Characters do not drift into generic assistants

When a character starts sliding into a generic “helpful assistant” tone, Moonborn catches it before the response reaches the user.

Find weak spots before users do

Role-break attempts, contradiction tests, and jailbreak probes reveal weak spots before the character goes live.

Define once, keep the same character in every channel

Use the same character in a chatbot, support flow, game scene, research panel, or brand channel. Integrate with APIs, SDKs, and compatible endpoints.
