The Best of JacHacks Winter
The projects that stood out, built in 24 hours at U-M North Campus, April 2026.
GraphClaw
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.
GhostWatch
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.
PolyWatch
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.
SybilScope
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.
Hijac
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.
Jac in the Block
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.
ChainViz
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.
6th Sense
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.
Corpus
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.
Inocula
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.
