Overview

Generic AI chat surfaces feel cold and forgettable. ChatC makes the relationship between user and character the centerpiece — discoverable, customizable, and persistent.

Challenge

Maintaining character consistency across long sessions is hard. Hallucination can break immersion. Latency directly impacts perceived intimacy. And consumer expectations on response quality are higher than B2B because users have no domain to translate from.

Approach

Per-character memory via vector store, hybrid retrieval (BM25 + semantic + reranker), answer-capsule formatting with source attribution where relevant, and an LLM-as-judge eval running continuously against a frozen test set per character archetype.

Result

Sub-2-second p95 latency, hallucination tightly bounded by per-character grounding, and a persistent-memory pattern that keeps characters consistent across sessions.
