Harth vs PLANA

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.

PLANA is a workspace for architecture and interiors that combines AI rendering, collaboration, and node-based workflows. In a browser, users can turn photos, sketches, or 3D models into photorealistic visuals. They can connect nodes to make rendering pipelines without code and save workflows as reusable templates. Workflows can also turn renders into video walkthroughs and produce structured, branded client proposals. Projects sit within hierarchical workspaces, with search across projects and files. PLANA offers web access, self-hosted deployment, and API access; enterprise options include integration with existing systems, dedicated server environments, on-premise software, and early API access. Enterprise controls include custom roles, permissions, organization management, and SCIM provisioning. A new account receives one 7-day Max trial without a card, which stops automatically without charge. Starter costs $8 a month and includes 500 monthly credits, one project, up to 2K image generation, and 5GB storage. Pro costs $20 a month and Max costs $50 a month.
