Software Mansion x Gemini Hackathon

Registration is now closed, we have reached the space limit – thank you for all the applications! The best software happens when smart AI meets great engineering. This hackathon brings together Google’s Gemini 3 – the most advanced Google AI model yet – and Software Mansion’s world-class technology stack. Please note that this is in-person event only. Maximum team size is 4. All attendees must submit an application for approval. You can register your team and idea by joining the Luma event. Tracks Track 1: Hybrid Intelligence The smartest AI systems won't choose between cloud and edge – they'll use both. On-device models have gotten fast and capable, but they still can't match the cloud for complex reasoning. This track challenges you to build multi-layered systems that think locally and reason globally. Tech to explore: React Native ExecuTorch for on-device inference, Gemma 3, Gemini APISpark ideas (don't copy these!): Privacy Scrub: Gemma filters sensitive data from documents locally; only safe content reaches Gemini for analysis.Context-Aware Assistant: Local RAG retrieves your photos, files, and calendar on-device, Gemini synthesizes personalized insights on top.Log Triage: Thousands of log lines would burn through cloud tokens. Gemma extracts the critical 50 lines locally, Gemini diagnoses the root cause. Track 2: Real-Time Multimodal AI We're past the "type and wait" era. AI can now see, hear, and respond. Build systems where AI responds to live media or transforms it in real time. Think assistants that watch and guide, or broadcast tools that composite, translate, and augment video streams on the fly. Multi-user scenarios are especially welcome. Tech to explore: Gemini Live API, Fishjam (real-time streaming infrastructure), Smelter (real-time video compositor) Spark ideas (don't copy these!): Remote Repair Assistant: A hands-free guide that watches you fix a circuit board via your phone camera, providing voice instructions and correcting your movements in real time.Live Study Group: Multiple students share screens with an AI tutor that sees everyone's work simultaneously and facilitates discussion.Reactive Broadcast: Stream a cooking show where AI generates ingredient lists, timers, and nutritional overlays as you cook – composed into the video in real time. Track 3: Surprise! It’s a game jam! You probably aren't a game developer. That only makes it more fun. Game development used to require years of specialized knowledge. With tools like Google's Antigravity and real-time AI APIs, the barrier has collapsed. This track is your invitation to build something playable. AI can be the core mechanic, the content engine, or the dungeon master running the show behind the scenes. We're looking for experimental, surprising, and genuinely fun experiences. Tech to explore: Antigravity, Gemini Live API, Fishjam, Smelter, MediaPipe Spark ideas (don't copy these!): Pufferfish (puffer.fishjam.io): A multiplayer tech demo using MediaPipe face-tracking and Smelter's real-time video composition—players become pufferfish, controlled by puckering their lips at the camera.Deep Sea Stories (deepsea.fishjam.io): A conversational mystery game where multiple players interact with a shared AI voice agent powered by Gemini Live API and FishjamFreysa (freysa.ai/act-i): An adversarial prompting game where players compete to convince an AI guardian to break its core directive and release a prize pool. Teams 1-4 Hackers per team – single-person teams are welcome!
