The Best of JacHacks A2Tech
The standout projects, built over two days at the University of Michigan during a2Tech360, September 2026.
Trace
Miguel Orti Vila, Anshu Pathak, Aidana Kuat, Gabriel Salvatore
Keeps every report from a disaster in one Jac graph of sources, claims, people, and places, so responders can see where each claim came from while an agent traces relayed reports back to their source for human review.
ClaimSure AI
Abhayjit Singh Gulati, Shankhanil Borthakur, Sri Satya Vinay Venneti, Adithyan Raja
Two Jac walkers share one graph: one flags health insurance claims likely to be denied before they are filed, the other reads a denial letter, finds the plan clause it contradicts, and drafts a cited appeal for a person to approve.
BlindSpot
Sakeena Patel, Lena Abedali
Reads a Python repo and its coverage report, builds a Jac call graph, and flags the untested functions that other code actually depends on, with a Gemini agent over MCP ranking what to test first.
M-Local
Rohan Maxa, Travis Jones, Manthan Patil, Adam Jiang
A UMich-first platform where local businesses publish offers and students discover, save, and claim them, with QR redemption so businesses can see it working.
Road to Research
Melody Bai, Lucero Toral
Helps students find professors by department, research area, and name, with recent papers and subfields from OpenAlex, grants, and any public note that a lab is hiring.
Adoptable Pet Match
Elizabeth C.
Adopters fill out a quick lifestyle profile and AI matches them with the Humane Society of Huron Valley pets that fit them best, built solo on JacHammer as a first hackathon project.
CounterSign MCP
Arnav D, Pradhum Niroula, Sidhant Singh, Arihan Iyer
Sits between an AI agent and the payment provider, vetting the whole spending plan and then every purchase with budget rules and an LLM judge before a single dollar moves.
Red Queen
Yorg Kattukaran, Isaac Poothullil, Pranav Nandyalam, Jayden Huang
An AI red team and blue team for your code: one agent finds real exploits, another patches them, and a referee re-fires every attack and reruns the app's health checks to prove each fix works.
Cirql
Sohum Kapoor, Jesse Chang
A personal CRM where agents walk your relationship graph: a 30 second voice memo becomes people and promises, and friends' agents find warm intros without exposing names.
