Blue Moon AI vs Harth

Blue Moon AI is a web workspace for turning architectural sketches, elevations, facade plans, and 3D models into photorealistic renderings. Its Render tool supports exterior, interior, and text-based visualization workflows, while users can revise designs with written instructions or a brush. Virtual staging adds furnishings to room photos while aiming to retain their walls, windows, and layout. Other listed tools handle floor plans, upscaling, animation, vectorization, and converting photos into textured 3D models. Canvas gives teams a shared real-time workspace with pooled credits, version history, and generation lineage. Most single renders use one credit, though Pro models and higher-definition settings may use more. Unused subscription credits roll over while a subscription remains active, subject to the plan’s maximum balance: 1,000 for Light and Student, 3,000 for Standard, and 15,000 for Professional. The Free plan costs nothing and includes five daily generations on the Free Daily model and three signup credits; daily generations reset at midnight UTC. The site says renders and edits are licensed for commercial use. CAD/BIM import is not supported.

Harth is a browser-based workspace for architecture practices to design, research, collaborate on, and present projects, with AI agents working on building data. It imports Revit, Archicad, SketchUp, and IFC models while preserving elements and coordinates. About 40 discipline-specific agent skills address areas such as structure, envelope, interiors, and analysis. For site context, it offers 3D satellite terrain, nearby-building imports, boundary tracing, geolocation, and sun studies. Users can render a model view, apply masking and lighting presets, and upscale images for print. Teams can work together using live cursors, presence, threaded comments pinned over 3D, and project voice. Harth also converts 360-camera footage into an explorable, measurable 3D scan, with processing stated at one to two days. Exports include PDF, image, and 3D files, 360-degree views, and recorded walkthroughs. All plans include the full workspace and differ by AI usage; monthly credits can be topped up with packs. Free includes 700 credits per month; Plus is $59 per month for 5,000 credits, and Pro is $149 per month for 15,000.
