Safeguarding
A five-stage pipeline between every child and every reply.
Safety isn't a setting in H.A.R.P.E.R. — it's the architecture. Every prompt is screened, every reply re-screened, every signal logged.
01Live
Pre-screening
Every prompt is classified for intent, sentiment and risk before it reaches a model.
02Live
Policy routing
Blocked categories are refused inline; monitored patterns are tagged for review.
03Live
Agent response
Curriculum-aligned reply generated within the agent's character and reading age.
04Live
Post-screening
The reply is re-checked for safety, tone and accuracy before the child sees it.
05Live
Audit & escalation
Severity-scored, logged, and escalated to a human safeguarding lead when needed.
Live safeguarding playground · scripted demo
