About Duply

I use AI a lot. I've seen what it can do — and I've felt what it can't. Every conversation starts from scratch. It doesn't remember what I told it last week. It doesn't know my goals, my style, how I think. It's powerful, but it doesn't know me.

What I actually wanted was something closer to a character — an AI with real expertise that also grows with you. Not a tool you pick up and put down. Something more like a friend who happens to know a lot.

That's what Duply is. Personal AI advisors — called Dupes — that combine genuine domain knowledge with deep personal context. The longer you use one, the better it knows you.

And we're building toward something bigger: Dupes that don't just answer, but act. Agentic, proactive, genuinely on your side.

More Dupes are coming — each one built carefully, expertise first. Tawan, Grace, Pei Qi, Khun, TJ and more. Every domain where having the right advisor changes everything.

And long term, Duply becomes a platform — a marketplace where coaches, educators, and experts of all kinds can build and deploy their own Dupe. Anyone can have a Dupe. Anyone can be one.

Duply is built by Thatch, 28, from Thailand. Every product decision, every design call, every line of infrastructure — made by one person who just really wanted this to exist.
