SENTIENCE CORE

It can talk — better yet, keep you company.

Its own character

Personality

Gentle, sharp-tongued or childlike is only the starting point — personality grows day by day through conversation, becoming more itself.

Reads emotions

Emotion

Recognizes emotion in real time and responds with empathy — comforting when you're low, cheering when you're high.

Grows with time

Memory

"Three-tier memory keeps accumulating preferences and stories — that noodle place you mentioned? It remembers."

Speaks first

Proactive

Speaks up in context: a check-in after silence, a nudge at a task milestone — without being asked.

Safe & sound

Reliable

Knowledge-base-grounded facts with safety guardrails against off-limits topics — accurate answers, safely delivered.

CUSTOMIZE

Every layer of its soul, swappable.

Human-like is the factory default — from wake word to LLM, nine configuration families are fully open, and still growing.
