Synthara

2026M
Secure & Govern MCP Track — Winner

MCP Security Governance

Hackathon for MCP & AI Agents (Solo.io)
Kubernetes-native governance for MCP infrastructure: it watches agentgateway and kagent resources, scores security posture per MCP server, and explains the risks using Gemini or Ollama.
2026C
Development Track — Grand Prize

ClipMind

放送局合同 AI ハッカソン (Google Cloud)
Drop in a long broadcast video and it works out the edit plan, picks the scenes and writes the captions to produce a social-ready short. Afterwards you can still adjust it by chat — 'make the captions yellow' — and it took the top spot against 28 teams from Japanese broadcasters.
2026A
Grand Prize

Anatom-AI

第4回 Agentic AI Hackathon with Google Cloud
A 3D anatomy atlas driven by plain language. Ask about cerebral infarction and the AI picks the relevant organs and vessels, renders them in 3D and adds an explanation. Interpretation, identification and drawing are separate stages, holding down wrong displays, and ambiguous input comes back as candidates to confirm.

Encouragement Award

DIAMONDMIND

第4回 Agentic AI Hackathon with Google Cloud
An analysis platform for baseball teams short of both coaching and money. Pose estimation from video turns a player's movement into numbers, replacing instruction based on feel with feedback in figures and words. It also fields position-specific questions and suggests training menus, on a serverless setup that keeps costs low.

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.
2026O
Grand Prize (Graduate Track)

Opioid Action Engine

USAII Global AI Hackathon 2026
A decision-support tool for the people who have to answer the opioid crisis on the ground: county health directors, lawmakers and advocacy groups. It shows how large the problem has grown, guides the user through shaping a response, then puts a price on that response alongside the savings it could produce.
2025C
Grand Prize

Cart-to-Kitchen AI Assistant

GKE Turns 10 Hackathon (Google Cloud)
Analyzes your grocery cart and recommends recipes, built on Gemini, GKE Autopilot, ADK and A2A. Grand prize among 4,773 participants from 133 countries; the winner spoke at KubeCon.

V-Commerce Studio

GKE Turns 10 Hackathon (Google Cloud)
Intelligent retail automation with personalized chat, virtual try-ons and instant ad generation, orchestrated on Gemini and GKE.
2025F
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.
2025V
3rd Place

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.
2025魔
Excellence Award

魔法の天秤 with Gemini

第3回 AI Agent Hackathon with Google Cloud
A physical device that turns a petty argument into a debate tournament. Each side speaks in turn; the speech is transcribed and an LLM moderates, scoring on logic and whether claims are backed up. The score travels over MCP to BLE motor control and appears as the tilt of real scales. Swap the prompt and the rules change.

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.
