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.

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.

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.

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.

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.

フクシア
第3回 AI Agent Hackathon with Google Cloud
An agent aimed at the paperwork load on social workers. It fills a client's assessment items from an interview transcript, then searches a custom RAG index of support programmes in Yamagata Prefecture and lists fitting ones as tasks. A plain UI works where paper and digital coexist, returning time to face-to-face support.

Award of Excellence
RouteKeeperAI
第3回 AI Agent Hackathon with Google Cloud
A system that surfaces road hazards before you drive them. It pulls Street View imagery every 50 metres along a chosen route and has AI analyse each point from several angles — blind corners, road surface, visibility — scoring risk on a ten-point scale. The result is a colour-coded map you can question spot by spot in chat.

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.

Flutter + Firebase Award
Flare
AI Agent Hackathon with Google Cloud(第1回)
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.
