Grand Prize — AI Agent Hackathon with Google Cloud(第1回) 2024

eCoino

A supply chain plan that drifts from reality can become a stockout before the analysis is done. eCoino keeps several response scenarios side by side in a BI view and lets planners work through them with a facilitator-style AI agent that drafts countermeasures quickly. Gathering is delegated; the decision stays human.

Why It Won — our reading

The Grand Prize at the first edition suggests the judges rewarded how unglamorous and concrete the subject matter is. Handling stockouts is ordinary work, but delay turns directly into loss for whoever owns it. The design likely helped too: the agent stays a partner that assembles options in conversation rather than a system that decides, so accountability never blurs. Building it on a BigQuery and dbt data layer probably signalled how close this sits to real operations.

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

Manabiya AI

AI Agent Hackathon with Google Cloud(第1回)
An end-to-end teaching assistant for new English teachers at tablet-equipped junior high schools. It spans lesson prep, the class itself, automatic quiz generation and grading, and per-student feedback. Classroom audio is transcribed so questions match what was taught, and wrong answers are analysed class-wide.

社内のぞき見新聞 ~The Internal Times~

AI Agent Hackathon with Google Cloud(第1回)
As an organisation grows, teams lose sight of each other's work and editing the internal newsletter turns into a chore. Here AI agents read company chat and meeting notes on a schedule, then lay the week out as a newspaper page, editorials and staff profiles included, so internal news becomes something people read for fun.

Flutter Award

AI StoryTeller

AI Agent Hackathon with Google Cloud(第1回)
A web app for households where two working parents and the price of picture books squeeze out bedtime stories. Pick an age, a script, a length and a genre, and the AI writes a story, illustrates it and reads it aloud. At around a dozen yen per episode, a fresh book can match the child's stage and interests every time.

Firebase Award

BLOOMS

AI Agent Hackathon with Google Cloud(第1回)
Pregnancy brings changes day by day, and memory alone makes them hard to describe at a check-up. BLOOMS is an iOS and web app that takes over the record-keeping: generative AI responds to the notes and photos a user leaves, suggests keywords to look things up, and summarises a stretch of entries to bring to an appointment.

Encouragement Award

COCO

第4回 Agentic AI Hackathon with Google Cloud
An AI partner for finding things around the house. It watches the room at intervals, keeping a log of footage, so asked where the keys are it reports not just a place but a state, such as hidden under a magazine. If they are absent, it reasons from calendar entries to suggest candidates, and turns its camera with a servo.

Encouragement Award

ARTESTERISM

第4回 Agentic AI Hackathon with Google Cloud
A platform linking museums and visitors. From a painting's image, AI writes commentary at three difficulty levels in several languages, delivered as an audio guide. Preferences left on each work are matched against embeddings to suggest what to see next and where it hangs, while museums see a per-work view of how pieces land.

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.

Excellence Award

KOTOWARI Link

第4回 Agentic AI Hackathon with Google Cloud
An app that lays the laws behind everyday scenes over the scenes themselves in AR. Pick a difficulty and a field, point a phone at a fountain or a bridge, and an AI reads the image and draws trajectories and force vectors on top of what the camera sees. If curiosity goes further, a link leads to a fuller written explanation.
