Dead Star AI — A Human-in-the-Loop Reasoning Engine Built on Gemma 4 This is my submission for the Gemma 4 Challenge: Build with Gemma 4 What I Built I work with LLMs constantly and I've hit the same wall dozens of times. You write a careful prompt, attach a complex diagram, and wait. If the model misreads one assumption in the middle of its reasoning, the final answer is wrong and you have no idea where. You just try again. Dead Star AI is what I built to fix that. It's not a chatbot. When you give it a problem, it streams its reasoning into discrete logic nodes on your screen before generating an answer. And before it commits to that answer, it stops — and gives you the keyboard back. You can click any reasoning node and rewrite it. If the model misread your database schema from an image upload, you fix that node directly, hit Commit Intelligence , and the final answer gets generated from your corrected reasoning — not as a patch, but as the actual starting point.…
