Winners of AI Agent Hackathon with Google Cloud（第1回）

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.

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.

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.

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.

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.

An AI coding agent aimed at the cost and time a mobile MVP takes. Describe the app you want in plain language and it writes Flutter code you can preview on the spot, and when the build breaks it repairs its own errors. Finished apps ship to Firebase in one click, letting a solo developer cycle through prototypes quickly.

A phone app for travellers stuck in front of an unreadable menu. OCR pulls dish names and prices from a photo, then adds a translation, a short explanation and a generated image so you can picture the taste and look. Pick a dish and the app renders your order in the local language to show the waiter, and it keeps past lookups.

A weekend outing planner for families with small children. Register the area you live in and the agent keeps collecting local events from the web into a database, then uses vector search to surface the ones closest to your tastes. Pick one and it builds a full day around it, including travel, meals and places to change a nappy.
