Tech Deep Dive Award — 第2回 AI Agent Hackathon with Google Cloud 2025

Smart Twin Room

A shopping app for when you cannot tell if furniture will fit your room. AI reads dimensions and existing pieces from photos and builds a 3D digital twin. Products drop into that twin for checking, and because the AI knows what is on screen and where things sit, you can ask for advice, or a search, without explaining.

From the organizer's citation (summary)

Judges called the link between e-commerce and a digital twin forward-looking, praising an experience aimed at furnishing a room, not merely searching, AI that blends naturally, implementation strength with Three.js, and potential reaching logistics.

Why It Won — our reading

The award name names the criterion: technical depth. Estimating dimensions from photographs, rebuilding the room in 3D, rendering it and layering products into it are jobs of very different kinds, bundled into one application. The quieter move is that the AI holds the current view and coordinates, removing the need to describe your situation before asking anything. That attacks a familiar weakness of conversational interfaces, and likely sits near the heart of the result.

This is our own analysis based on the official announcement and the project's own materials. It is not the organizer's stated reasoning.

Grand Prize

FlatJam

第2回 AI Agent Hackathon with Google Cloud
A composition aid for school music classes. A student describes in their own words the song they want to make, and the AI proposes chord progressions and melodic techniques that could fit. It stops short of writing the piece itself: students try options and choose, bringing individual creativity into uniform-feeling lessons.

学校だよりAI

第2回 AI Agent Hackathon with Google Cloud
A tool for primary and junior high teachers who lose hours each week writing class newsletters. Teachers just talk to it: the AI asks back for missing details, assembles the draft, and outputs HTML or PDF laid out to survive A4 printing. Because it keeps the paper habit intact, even teachers uneasy with IT can adopt it.

Vibe Planning

第2回 AI Agent Hackathon with Google Cloud
A declarative travel planner that starts from a mood rather than a destination list, say wanting to kayak on a quiet lake, and builds an itinerary from it. It reads across popular spots, hour-by-hour crowd data and reviews, then orders stops to dodge the busy hours. Change your mind mid-chat and it recomputes on the spot.

Firebase Award

AIMeeBo

第2回 AI Agent Hackathon with Google Cloud
A dashboard app that transcribes a meeting in the browser as it happens, then has a lead AI dispatch work to specialist agents that assemble tasks, owners, decisions, agenda items and a summary diagram. The facilitator is freed from note-taking, and when the meeting ends an organised board is already on everyone's screen.
