In their own words
ArkoAI
ArkoAI turns architectural models and active views into AI-generated renders. It connects with Rhino, SketchUp, and Revit, and users of SketchUp or Revit can render directly from the view open in the modeling software. Discipline and style controls guide the generated image. The SketchUp plugin supports versions 2021–2026 on Windows and macOS; the Revit plugin supports versions 2021–2026.
ArkoAI is available on macOS, Windows, and the web. It offers a free trial but no free plan, followed by monthly or yearly subscriptions that can be updated or canceled at any time. Each tier includes a fixed monthly quota of high-priority renders. The Pro toolset includes seed settings and negative prompts for the basic model, high-quality resolution settings, and the subscriber-only Pro Model, described as retaining geometry. The pricing page lists a 608-pixel maximum image height for the free basic model and an average image height of 768 pixels for the Pro Model. Users own their renders, and final outputs are stored on the user's device. ArkoAI says it does not retain inputs or outputs on its servers after a session or task, though data may be sent to third-party providers for real-time processing.
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.
