ArkoAI vs Rendero

ArkoAI turns architectural models and active views into AI-generated renders. It connects with Rhino, SketchUp, and Revit, and users of SketchUp or Revit can render directly from the view open in the modeling software. Discipline and style controls guide the generated image. The SketchUp plugin supports versions 2021–2026 on Windows and macOS; the Revit plugin supports versions 2021–2026.

ArkoAI is available on macOS, Windows, and the web. It offers a free trial but no free plan, followed by monthly or yearly subscriptions that can be updated or canceled at any time. Each tier includes a fixed monthly quota of high-priority renders. The Pro toolset includes seed settings and negative prompts for the basic model, high-quality resolution settings, and the subscriber-only Pro Model, described as retaining geometry. The pricing page lists a 608-pixel maximum image height for the free basic model and an average image height of 768 pixels for the Pro Model. Users own their renders, and final outputs are stored on the user's device. ArkoAI says it does not retain inputs or outputs on its servers after a session or task, though data may be sent to third-party providers for real-time processing.

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.
