The record

Purpose: SecondRender turns architectural sketches and model screenshots into photorealistic renders with AI.
Supported inputs: It accepts hand drawings, digital drawings, SketchUp, Rhino and Revit screenshots, and existing renders as input.
Render time: The maker says an image arrives in about 30 seconds.
Scenario controls: Users can set architectural style, time of day, weather, season, environment and vegetation using presets or manual settings.
Reusable styles: Save as style carries a reusable visual identity across a project while preserving the source geometry’s look-independent design.
Fidelity mode: The maker says fidelity mode keeps the source authoritative and preserves geometry and physical materials.
Export: The maker says final images can be upscaled and exported at 4K.
Output variability: The maker says the same input does not guarantee the same output, and matching objects detail for detail across perspectives remains difficult.
Notable limit: The maker says SecondRender is not intended for visualization specialists producing hero images that require detailed control of lighting and materials.
Free use and demo: The maker offers one free render and a free 30-minute live demo.
Revit integration limit: SecondRender runs outside Revit, has no Revit plugin and does not read BIM data; users upload a screenshot or exported image.
Cloud operation: The maker says SecondRender runs in the cloud, so an office laptop is sufficient.
Founder and support: Founder Marcus Horndt says he handles product demos and support questions himself.
Maker identity: The about page describes SecondRender as a solofounder-built product made together with practicing architects.
