In their own words
Rendero
Rendero is a browser-based AI rendering and image refinement platform for architectural visualization. It helps design teams explore visual directions, materials, atmosphere, and presentation drafts from existing images rather than model files. Users can upload PNG, JPG, or WebP sketches, clay renders, exported model views, or other visuals. Automatic segmentation lets users select image regions for refinement and compare options. The site lists Nano Banana, Nano Banana 2, Nano Banana Pro, GPT Image 2, and Stable Diffusion, although model and resolution access depend on the plan. Rendero works alongside modeling tools: users export images from SketchUp, Revit, Rhino, ArchiCAD, Vectorworks, or Blender for use in the browser. The free plan gives a one-time 50-credit allowance that does not refill monthly. Paid plans start at $19/mo; Lite is $19 a month for 300 credits. Credit charges vary by model and resolution, some engines also account for processing time, and upscaling costs extra credits. Generated images may alter geometry or details, so they need review and are not technical or construction documents.
