In their own words
Gendo
Gendo is a web-based collaborative canvas for architectural visualization. Architects and designers can generate renders from sketches, change materials, populate scenes, transfer styles, enhance images, and upscale renders to 4× resolution. Its natural-language assistant can use workspace tools, and teams can run simultaneous generations, share images, add comments and notes, and iterate together. Users bring scenes or views into the canvas by exporting them; direct plugins for Revit, SketchUp, and Blender are on the roadmap. The free plan includes Material Bank material specification, but its prompts and outputs are not treated as confidential. Studio and Enterprise prompts and outputs are contractually protected from AI training and marketing use. Gendo says data is stored in EU data centres, encrypted at rest with AES-256 and in transit with TLS. Free costs nothing; Studio costs £66 a year, billed annually at £66/mo (£790/year; excl. tax).
Harth
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.
