Gestalt
Built at GPT-6 Astra Hackathon NYC · Sep 10, 2026 · New York, NY

Gestalt is a visual workspace for steering AI coding agents and understanding the software they build. AI can generate code faster than people can review it line by line. Gestalt connects the running application, its implementation, and the agent’s work so you can guide changes through visible outcomes and architecture. The application runs beside an interactive code map. You can point at the interface, annotate a screenshot, select an architectural region, and send that context to Astra in one prompt. The agent receives the images alongside structured information about the selected code and dependencies. You can move from “make this less squiggly” to “show me where this is implemented,” then explore how that implementation connects to the rest of the system. You can prompt directly on the code map itself and send both the visual representation and the dependencies as context to the coding agent. Gestalt also records the session so you can review its decisions, changes, checks, and remaining uncertainty. The code map follows agent activity, while history lets you revisit how the application evolved. This makes architectural impact and the reasoning behind changes easier to inspect, with source code and diffs available for detail. Base of the code galaxy (dependency analyzer and architecture generation) was built at a previous hackathon, everything else was built today (total ~10h with astra)
