SecondRender: AI rendering for architects

Architectural sketches, rendered in seconds. SecondRender (also written 2nd Render) transforms hand-drawn sketches, SketchUp and Revit models into photorealistic architectural renders with AI.

Traditional rendering pipelines are slow, expensive, and require specialized software. SecondRender needs no 3D modeling suites, no material libraries, no render farms: upload your sketch or model screenshot and get client-ready visuals in seconds, not hours. Show clients realistic visions of their project before committing to detailed plans.

Founded by Marcus Horndt, built together with architects.
