Nomad-Quest Game
Track 09GDG Brooklyn
Nomad-Quest Game

Nomad Quest is an interactive travel etiquette and cultural survival simulator. Instead of reading dry travel blogs or memorizing standard phrases, users are dropped into immersive "24-hour" city scenarios where they must navigate real-world dilemmas, cultural nuances, and language barriers. It gamifies global citizenship—rewarding players with passport stamps and respect points as they learn how to navigate new cultures without making costly, awkward tourist mistakes.

The "Homework" Trap: It was surprising how quickly educational content can accidentally feel like a school assignment (the "Quizlet effect"). We realized that simply having good information isn't enough; the delivery has to be dynamic. By introducing bouncy, engaging animations and restyling the scenarios to feel like an adventure game rather than a multiple-choice test, the exact same educational

Nestwork
Track 09GDG Brooklyn
Nestwork

Nestwork matches small groups of compatible strangers in NYC - by shared interests like tech, wellness, trekking, or being new to the city - and sends them a curated invitation to a real evening out, itinerary and venues included. Every member is ID-verified before their first Nest, so meeting strangers actually feels safe. Once you RSVP, a scoped group chat opens just for your Nest, active through the event and archived after - no lingering inbox, no swiping.

We assumed the hard part would be the matching algorithm. It wasn't - the hard part was realizing trust, not compatibility, was the real blocker to strangers meeting up. The ID verification step ended up being the feature people cared about most.

LISTA Speech Recognizer

LISTA Speech Recognizer

By training the keywords independently to automatically access the Google AI Studio webpage.

Recently, I have been working on a project related to smart home, so I chose a similar direction.

ForgeIQ: Multimodal Engineering Intelligence
Track 09GDG Brooklyn
ForgeIQ: Multimodal Engineering Intelligence

ForgeIQ is a multimodal engineering intelligence platform powered by Gemini that analyzes technical drawings and component images. Users upload engineering artifacts and receive structured AI-assisted reviews including design analysis, manufacturability (DFM), material recommendations, preliminary FMEA, quality inspection checklists, and prioritized engineering recommendations. ForgeIQ helps engineers evaluate designs faster while keeping the human engineer in the decision loop.

I was surprised by how much structured engineering insight Gemini could generate from a single technical drawing. The biggest challenge was designing prompts that produced engineering-focused analyses rather than generic image descriptions.

scout
Track 09GDG Brooklyn
scout

Scout is an AI apartment-hunting agent for NYC renters. It turns plain-English preferences into listing searches, ranks and enriches the matches, and organizes next steps in one map-first tracker. It can also draft broker outreach so renters can move quickly while staying in control of what gets sent.

I expected the AI to be most useful for writing messages, but its biggest value was translating messy human preferences into precise search filters. Once Scout understood requests like “a no-fee two-bedroom under $5,000,” the rest of the workflow became dramatically simpler.

Food Hunting
Track 09GDG Brooklyn
Food Hunting

Food Hunt allows you to pick your food when you don't know what to eat for lunch/dinner. The website will prompt you to enter basic information such as your address, the radius of the website, and your budget. Then it will ask you select the kind of food that you want right now.

It was a very tough project to do within a short amount of time. But we managed to finish on time

TeamPulse Project Manager
Track 09GDG Brooklyn
TeamPulse Project Manager

TeamPulse streamlines team collaboration by automatically assigning tasks to the most suitable team members. It allows teams to define each member's role, skills, and weekly availability, then intelligently matches unassigned tasks based on expertise and capacity. This helps teams, especially large or remote ones, delegate work more efficiently and complete projects more effectively.

What surprised me most during development was how seamlessly role-based AI task delegation transforms project planning. Rather than just assigning tasks randomly, evaluating member skills, weekly capacity hours, and target deadlines using Gemini AI produces surprisingly nuanced, practical workload recommendations.

IBM Escape Room
Track 09GDG Brooklyn
IBM Escape Room

This project is an Autonomous AI Escape Room Engine that leverages Yann LeCun’s JEPA architecture and Gemini 2.5 Flash to create procedurally generated 3D games. It utilizes a multi-agent framework where specialized modules like the Configurator and World Model collaborate to simulate the physics and logic of your environment. Players select unique themes and scenarios which the engine then transforms into an interactive, real-time 3D world using the Three.js library. The system moves beyond sim

Mapping Yann LeCun’s JEPA paper directly to game master mechanics revealed that modular brain agents (Configurator, World Model, Critic, Actor) naturally eliminate AI hallucinations by simulating spatial physics before narrative generation. We were surprised by how seamlessly an LLM orchestrator could generate real-time 3D spatial JSON protocols while maintaining strict object permanence across ga

Pocket Maps

Pocket Maps

Pocket Map is a mood-driven location discovery app where users snap and pin cozy hidden gems to a shared map. Guided by Pickles, an empathetic AI raccoon companion, users describe how they feel—and Pickles analyzes community photos to match their exact vibe with the perfect local sanctuary.

We are really surprised by the capabilities and speed of Google AI Studio.

Velocity Neon 3D

Velocity Neon 3D

The project involved creating an immersive 3D racing game set in a captivating sci-fi universe. Players find themselves in a futuristic landscape filled with neon-lit cityscapes and breathtaking alien terrains.

Google Pro is an advanced and versatile modeling tool that allows users to quickly prototype and craft immersive 3D environments. With its intuitive interface and robust features, you can seamlessly bring your creative visions to life, transforming ideas into vibrant digital landscapes almost instantly.

Vibe Style
Track 01GDG Brooklyn
Vibe Style

This app is a conversational AI stylist for your closet: it asks about your mood, who you’re dressing for, and the occasion (or trip details), then generates complete, head-to-toe outfits pulled from your own digitized wardrobe — shown as e-commerce-style look cards with Add to Bag, Favorite, and Customize options. It also handles multi-person trip packing (partner/family), weather-aware travel essentials, and destination-only shopping suggestions, all wrapped in a friendly “best friend stylist”

I assumed the hard part would be the styling logic. It wasn’t, the hard part was getting the AI to remember it already knew you were shopping solo, and to stop asking.

VibeTrav
Track 09GDG Brooklyn
VibeTrav

VibeTrav is a medical tourism platform that helps people discover and plan authentic healthcare journeys, with a dedicated focus on Ayurveda. The new Ayurveda Centers feature lets users explore highly recommended treatment centers first, then browse a wider directory with powerful filters by location, treatment type, and budget. It is designed for international patients seeking trusted, high-quality Ayurvedic care without the usual research overwhelm.

What surprised me most was how strongly users wanted a clear separation between “highly recommended” centers and the broader list. Prioritizing quality over quantity proved more important than simply showing a large number of options.
