AI Hackathon Winners of 2025

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.

A phone and tablet recipe app built around the annoyances of cooking: messy hands, jargon you keep looking up, paper recipes you cannot use. A wake word starts voice control that answers instantly from a local model, and questions about terms or substitutions are handled with RAG. Photograph a magazine page and it becomes data.

An AI choreographer that generates personalized Bachata sequences by matching music features to labeled dance clips.

Transforms cosmetics retail: analyzes customer data across store, EC and counseling touchpoints to generate personalized recommendations that close the gap between veteran and novice staff. Won among 37 teams.

A visual AI agent builder: describe agents in plain English, design visually, test instantly.

Reinvents credit pre-approval with a multi-agent pipeline that analyzes spending patterns and balances bank profitability with customer value.

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.

Conversational shopping through six specialized AI agents that understand style and learn preferences, deployed as a multi-agent architecture on GKE.

AI transaction analyzer that detects fraud, alerts users by email and takes reports via an AI voice assistant, using Llama API multimodality to cross-check client news.

Upload one photo of the furniture you want to build and this web app works out the parts, generates a 3D model, lays out the cutting and assembly steps, and exports a plan as a PDF. It targets DIY beginners who cannot draw plans and hesitate over materials, so they can start work already holding instructions they trust.

Democratizes education in Brazil: autonomous agents grade essays, build personalized study plans and generate mock exams.

Multi-agent AI transforming energy customer management through ADK orchestration.

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.

An app for experiencing race day before it arrives. It cross-references the course GPX, the weather and the runner's goals and training history, then works out which points to watch, how to pace and where to drink. The advice comes back as a generated video with captions, helping runners picture the course and judge well.

Processes 400-page geology reports with Llama 4 Maverick's long context and generates 3D subsurface models — built by a working geologist.

An AI team that continuously audits, forecasts and optimizes cloud infrastructure for sustainability.

A real-time ambulance routing engine on Microsoft Fabric: dispatch events landing in a mirrored Azure SQL database trigger a notebook via Activator, which combines the Google Routes API with an ML model predicting the speed advantage of siren privilege, surfaced to control rooms on a Power BI map. Built by an Italian developer.

A service that hands quotation work, long the preserve of veteran staff in woodworking shops, over to AI agents. The job is split into stages: read the PDF drawing, identify items and quantities, price the materials, produce the quote. At each stage a person checks, corrects and approves the AI's draft before it moves on.

An agent for foreign visitors caught in an earthquake or typhoon in Japan, unable to read the warnings or tell where to evacuate. Drawing on official meteorological and geospatial data plus preparedness guides, it delivers alerts, shelter directions and ready-to-send safety messages in the user's own language.

A CCTV control-room AI operator with zero fine-tuning: define surveillance events in plain language and Llama 4's multimodal vision detects and reports them.

A recipe recommender that structures raw recipe data with NLP and clusters dishes by theme and flavor profile, so users can ask in natural language and get personalized suggestions. Took third place as a practical showcase of text-based workflows.

A plug-and-play AI microservice for online stores: image mixing lets shoppers see themselves wearing the product, plus smart descriptions for accessibility.

Next-gen personalized education: interactive lessons with visuals, quizzes and smart AI support.

AI expert-matching for organizations: builds a knowledge graph from Jira, GitHub, internal docs and resumes — you can even query a person's digital twin before reaching out.

Converts natural language into validated Feynman diagrams using real physical laws — bridging theory, automation and symbolic reasoning.

A web service linking the owner of a lost pet with whoever spots it. One agent reads images, another predicts behaviour, and together they estimate from weather, time of day and terrain where the animal is likely to be, drawing it as a heat map. Finders' photos are auto-matched by similarity, and both sides can chat directly.

Route-aware event discovery: enter a route and time window, and hybrid semantic search plus geospatial-temporal filters surface events along the way.

A trajectory memory for robots: banks sensor-action sequences as vectors labeled by safety, then retrieves the safest neighbor to suggest the next move.

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.

An AI-powered SDR system: automated lead generation, research, proposal writing and outreach. Grand prize among 10,400 participants from 62 countries.

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.

An AI system that makes city waste collection smarter: it monitors bin fill levels, predicts when they will overflow, and dynamically reshuffles collection routes. Built by a Kenyan team with Fabric Data Agents, Copilot Studio and Azure OpenAI.

A space-weather analysis system for power grid operators: it predicts grid failures triggered by solar flares and serves up 7-day forecasts, risk thresholds and recommended actions, applying data engineering and ML to critical-infrastructure resilience.

Game NPCs that remember places and events via spatio-temporal memory — CLIP image memories plus text memories, running locally on ~3GB VRAM at 1-2s latency.

Multi-agent financial analysis platform that evaluates trading hypotheses, built on ADK and Vertex AI.

Intelligent retail automation with personalized chat, virtual try-ons and instant ad generation, orchestrated on Gemini and GKE.

Turns e-commerce discovery into an explorable 3D world — categories become mountains, result counts become terrain height, and an LLM guide narrates the tour.

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.

An automated pipeline that ingests raw technical demo videos from YouTube, distills their content into a structured knowledge base, and makes it searchable. Turning scattered video into queryable data won it first place in the inaugural Free Edition hackathon spanning 16 countries.

A quiz game weaving the theme 'Light' through varied scenes, by team Kamomi — won on overall completeness in live demo judging.

Built by Kamie Shinju in a 45-minute sprint from the concept of 'excuse' — won the division on combined team and solo results for reliably working output.

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.

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.

A team of AI agents dividing strategy, copywriting and analysis inside Slack to run the marketing PDCA loop — 'a parallel AI workforce'.

A web app for marking handwritten exams. Questions and grading criteria are registered in advance; given a PDF of answers, three AI roles, sorting, transcription and commenting, draft the feedback. Teachers edit and place the comments on screen, then export a PDF, lifting a returned test from a bare score to real feedback.

A regional-revitalization agent that bridges municipalities, companies and prospective migrants — matching regions, jobs and programs through to post-move settlement.

The Robohon robot chats with elderly users via Agentforce, auto-writes daily reports shared to family on Slack, checks medication and flags health anomalies.

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.
