Who We Are

Human Intelligence Studio Limited is a software studio registered in Hong Kong. We design and build apps, software, and developer tools, sometimes using AI (we call it "Human Intelligence" because irony is fun).

We operate several products under one roof, sharing the same infrastructure and standards for security, privacy, and support.
