January 2026Idea InceptionThe concept for PrototypeOS is born — an AI-native platform to take a hardware engineer from a thought in their head to a fully assembled physical product using nothing but natural language.
23 April 2026Clear Roadmap FormedThe full product and business roadmap is locked in — six technical layers, acquisition targets, training data strategy, and IP plan.
23 – 25 April 2026Technology ExplorationRapid testing across different AI image, 3D generation, and CAD pipeline approaches to identify the strongest architecture.
26 April 2026Workflow Architecture LockedThe winning pipeline is identified: GPT Image 2 → OpenSCAD → Three.js → STL export. The full server-side and client-side architecture is defined.
27 April 2026Working Prototype Built & TestedCore functions of the platform are working end-to-end for the first time — natural language in, 3D geometry out. Internal testing begins.
28 April 2026UI PolishFull interface refinement pass — chat studio, 3D viewer, and export flows brought to a presentable standard.
29 – 30 April 2026Internal Colleague TestingTested with colleagues. Feedback gathered across the full workflow. Version 2 update shipped on 30th with fixes and improvements.
1 May 2026First Physical PrototypeA component designed in PrototypeOS is 3D printed and laser cut. The robot is trained with the physical parts for assembly tasks.Hardware milestone
2 May 2026Robot Successfully Assembles PartsRobot fully trained and autonomously assembles the 3D-printed components — the first full end-to-end loop from language to assembled product. Domain purchased.Full loop closed
