Luw.ai Studio vs Renderica

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.

Renderica uses AI to turn architectural sketches and plans into photorealistic renders. It extracts room dimensions and openings from a plan and conditions rendering on that geometry. Inputs include PDF, DXF, PNG, JPG, GLB, and GLTF files, as well as hand-drawn sketches, floor plans, CAD sketches, and Pinterest image URLs. The homepage lists compatibility with Revit, SketchUp, ArchiCAD, Rhino 3D, AutoCAD, Blender, 3ds Max, and Chief Architect. Users can select from 32 style presets and five lighting modes, provide Pinterest pins or image URLs as style references, and share a client review link or export a 4K PNG from the gallery. The Free plan costs nothing and includes three renders per month at 1024px; Starter costs $24 a month for 60 monthly renders at 2048px. Pro costs $59 a month and Studio costs $179 a month. Renderica says uploaded content is not used to train its own models. Its policy describes some stored assets as accessible through non-expiring unauthenticated URLs and is marked draft pending legal review. For non-rectangular rooms, openings may not be carved and angled walls may be omitted.
