Harth vs Treform

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.

Treform is an AI-native architecture platform that generates floor plans, 3D models, and renders from plain-language descriptions. It can create editable 3D massing from text prompts or reference photos, then use described changes to produce editable plans, sections, and elevations. Listed architectural guidance covers circulation, structure, daylight, and code, alongside area calculations and sun path analysis. Inputs include text prompts, reference photos, site addresses, and property lines. Treform Desktop is described as working with Rhino, Grasshopper, SketchUp, Revit, and Blender; the homepage also lists AutoCAD. Exports include DWG and PDF for plans, GLB, OBJ, and IFC for 3D models, and high-resolution PNG or JPG for renders. The Free plan allows 3 AI edits per month, has no rendering, and does not permit commercial use; exports are watermarked. Paid plans include a commercial license and start at $25 a month. Desktop is available for macOS Apple silicon and Windows 10/11 64-bit; Rhino use requires Rhino 8 SR29 or later.
