Marble
MarbleOS (branded simply as "Marble") is a desktop AI agent workspace that swaps the chat-thread interface for a card-based canvas, keeping every delegated task, its tools, and its output files visible while several agents run side by side.
Founders Akilan and Miguel Acevedo launched it via a Show HN post on July 31, 2026, framing it as AI's "GUI moment" after the command line — an explicit callback to Xerox PARC, the 1984 Macintosh, and NeXTSTEP. The post hit 124 points and 69 comments in a day, though it also collides with three unrelated products already named Marble.
Think of MarbleOS as a mission-control board for AI agents, replacing the walkie-talkie feel of a chat box.
