About 6 Sigma
We believe AI should enrich childhood — not replace it.
Technology that nurtures curiosity, creativity, and connection.
To create the safest, smartest, and most delightful AI companion for children — one that respects privacy, supports learning, and brings families closer together.
6 Sigma Limited was founded in 2026 in Hong Kong by a team of AI researchers and parents who saw a gap between the promise of AI and products safe enough for children. We set out to build something we'd trust with our own kids.
On-device AI from day one. Your child's data never leaves home.
Every feature tested through child safety, developmental psychology, and plain fun.
No hidden data collection. No manipulative design. We tell you exactly how it works.
