APO-HAL-EMS
Track 09Michigan, USA
APO-HAL-EMS

APO-HAL-EMS (Agnotic Policy Optimizer / Hardware Abstraction Layer For Energy Management Systems) is an architectural framework and universal governance layer designed for critical infrastructure control systems and energy management systems. ​It provides deterministic validation of automated, AI-driven, and human operator decisions before actions are committed to physical hardware or control networks.

I thought I'd have to do more work by constantly correcting and re-checking that my prompts were being followed with accuracy throughout the build. Gemini was pretty solid and made the process so much smoother, creating much less work for me due to high precision and follow-through.

SensePath
Track 09GDG Brooklyn
SensePath

SensePath is a voice-first accessibility assistant designed for blind and low-vision users. It combines Gemini Live, multimodal vision, and Google Maps Platform to help people navigate the last few meters of a journey—finding entrances, benches, elevators, and understanding their surroundings through natural conversation. The standout feature is its ability to seamlessly switch between navigation, object finding, and immersive scene descriptions while keeping the interaction hands-free and acces

We expected navigation to be the hardest problem, but the real challenge was making AI know when not to speak. Designing an assistant that gives timely, concise guidance without overwhelming or distracting the user turned out to be just as important as the underlying AI itself.

HarmonicBlend
Track 09GDG Brooklyn
HarmonicBlend

HarmonicBlend is an AI-powered, browser-based DJ and stem mashup workstation that allows users to search any song on YouTube Music and turn it into a professional-grade remix in real time. The platform features dual interactive vinyl turntables, scrubbable waveform timelines, 3-band EQs, lowpass/highpass filter sweeps, crossfader controls, and an offline WAV exporter that lets users render and download their completed mixes directly to disk, as well as using Facebook's Demucs ML to create stems.

Using Gemini within Google Antigravity to build this project was a leap in autonomous, agentic software engineering. Its crazy how Antigravity reasoned across full-stack boundaries, making Python Flask backends, setting up PyTorch ML pipelines, and coding complex Web Audio API DSP frontend engines, something I would need months of training and understanding to build.

Drop
Track 09GDG Brooklyn
Drop

Drop is a mobile-first web app that turns New York City into a live board game where physical items like disposable cameras and toys drift from stranger to stranger. Built for urban explorers and romantic wanderers, the app lets you drop and pick up items and monitor a drop's entire journey across the city while staying completely anonymous.

Google AI Studio is a surprisingly friendly entry point for non-developers, proving that you don’t need a traditional coding background to bring a complex spatial and interactive idea to life.

It added in suggestions to our build that we didn't even consider. It was a great addition!
