Luw.ai Studio vs Rendero

Luw.ai Studio is a browser-based floor-plan generator and 3D design studio that turns briefs, photos, sketches, and other supported inputs into editable scenes. Its in-editor AI architect uses more than 40 browser-side tools to create and edit measurable geometry that can be undone. The generator makes scaled 2D and 3D plans with walls, doors, windows, dimensions, and baseline room sizes and clearances. Users can furnish rooms from a catalog of more than 150 items, with placements checked against door swings and clearances. Rendering supports photorealistic or stylized 4K and 8K output, prompts, reference images, and day or night settings. Studio imports DXF and IFC, with IFC described as early alpha, and exports dimensioned PNG or SVG plans and GLB, OBJ, and STL models. Sharing supports view-only, download, or edit access; MCP access enables headless use with Claude Desktop, Cursor, or a user's own agent. The free plan offers two credits per day, while paid plans start at $19 per month.

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.
