A global 4-day hackathon.
Build AI-native apps with Jac — from anywhere on the planet.
JacHacks is going global. Same energy, same Jac language, no zip code required. Join hackers from around the world for 4 days of building.
Open to builders everywhere — no travel required. Hack from your dorm, home, or anywhere with Wi-Fi.
Non-stop building across May 15–19, 2026. From kickoff to demo — four full days of shipping.
Use the Jac language to build AI-native, graph-powered applications. Tutorials and mentors included.
Win prizes across multiple tracks — agentic AI, fintech, social impact, and more. Details dropping soon.
Reserve your spot for the global hackathon — May 15–19, 2026.
Powering the future of AI programming
24 hours. 70 projects. One unforgettable weekend at U-M North Campus.
The projects that stood out — built in 24 hours at U-M North Campus, April 2026.
A K M Mahmudul Kabir, Abdullah Al Mahmud
A multi-agent AI platform where memory lives in a property graph, agents are graph walkers, and skills can be installed from the internet at runtime.
Aaron Sun, Ayush Madhav Kumar
Autonomous code defense with graph-native clarity. Monitors repositories for risky dependency changes and PR signals, with automated sandboxed testing and optional fix generation.
Adam Christley, Caeden Kidd, Amar Zecevic, Schultz
AI powered insider trading detection for prediction markets. Uses Tree of Thought reasoning to autonomously investigate manipulation, coordinated wallets, and suspicious trading patterns.
David Chong, Yanshengtian Dong, Shrimann Myneni
Detects fake wallet clusters in crypto airdrops using Jac's native graph Walker and AI reasoning. Builds a live wallet graph to distinguish coordinated fraud from legitimate activity.
Meron Demissie, Nitin Shankar Madhu, Chuka Ezeoke
An AI-powered mobile agent that hijacks your routine. Monitors device sensors and automatically performs contextual actions based on detected patterns and user-defined rules.
Krish Deshmukh, Kuldeep Debnath, Junna Park, Adam
An accessible learning toolkit for Jac combining a block-based visual interface, real-time graph visualization, and a VS Code Extension Suite with linting and debugging support.
Darsh Poddar
3D visualization of npm's single points of failure — with autonomous Jac agents that investigate any package's blast radius in real time across 217K+ vulnerability records.
Raj, Adwayan Goswami, Aryan Singh, Param Natu
A real-time AI assistant that listens, reads social cues, and suggests what to say instantly — for interviews, networking, and high-pressure conversations.
Anirudh Manjesh
Your codebase has an immune system. Corpus watches AI-generated code, catches breakage before it lands, and self-heals your project against your codebase graph.
Marcel Billingslea, Jana Hazimeh, Sudarshan Sridhar
Expose the infection. Build the immunity. A full-spectrum Bluetooth attack and defense system that weaponizes the trust graph — then inoculates it.
