Welcome, builders!

Talking about AI is easy. Getting something to actually work by sundown is the hard part.

You have one day. Don't try to build everything. Pick one real problem, decide early what you're building, and make the strongest working product you can.

+81 Builders is a build community, not a talk community. Today is about leaving with something that runs.

Japanese and English are both spoken in this room. You don't need to speak both.

Requirements

Theme: Open — anything that uses AI and actually works

An AI agent, an app, any software that uses AI: all of it counts. It doesn't have to be an agent. If it uses AI and it runs, it's in. There's no set brief, so build whatever you want.

You're not expected to build production-ready software. A small project that clearly solves one painful problem beats a complicated product with ten unfinished features.
