Built from Seoul
One person. One mission. Just shipped.

OrangeAI is a solo-founder studio based in Seoul, South Korea. We build AI-powered apps that respect your privacy by keeping your data on your device.

Our philosophy: ship fast, validate with real users, and double down on what works. Every app starts as a PoC with a clear gate — 1,000 installs, 4.3+ stars, 50% activation in 90 days. Pass the gate, and we invest. Miss it, and we maintain.

We chose constraints over comfort. No servers means no server costs — and no way to see your data. That's not a limitation. That's the product.

How we build
🔒

Privacy by Architecture

We don't promise privacy. We architect it. No servers = no way to see your data. It's not policy. It's physics.

🚀

Ship, Then Perfect

Every app launches as a PoC. Real users give real feedback. We iterate based on data, not assumptions.

🎯

One Problem Per App

No feature bloat. Each app solves one specific problem and does it well. Complexity is the enemy of daily use.
