Our verdict on Harth
Harth is a browser-based AI workspace for architecture teams that need to turn building data into visual studies and rendered outputs. It supports imports from Revit, Archicad, SketchUp, and IFC, connecting AI architectural rendering and image editing with project models. The feature set also covers terrain and existing-building imports, 3D satellite terrain, sun studies, discipline-specific AI agents, multi-agent workflows, collaboration, shareable boards, and exports to PDF, images, and 3D formats. Its strongest fit is BIM-based architectural visualization rather than general-purpose image generation.
Pricing is organized around monthly AI credits. The Free plan costs $0 per month and includes 700 credits, 20+ renders, and community support. Plus costs $59 per month and provides 5,000 credits, 150+ renders, priority rendering, and email support. Pro costs $149 per month with 15,000 credits, 500+ renders, priority rendering, and priority support. One-time credit packs offer another purchasing route: Small costs $99 for 7,500 credits and 250+ renders, Medium costs $199 for 16,000 credits and 500+ renders, and Large costs $399 for 36,000 credits and 1,000+ renders. Credit packs never expire.
Harth’s main differentiator is the connection between AI tools and architectural context. Terrain, existing-building data, sun studies, discipline-specific agents, and multiplayer comments over 3D give teams more than a standalone rendering workflow. The Revit, Archicad, SketchUp, and IFC import options also support mixed-model environments. Teams should choose Harth when model-aware visualization, collaborative review, and flexible credit purchasing matter. Smaller projects can start with the Free plan, while higher-volume work is better aligned with Plus, Pro, or a credit pack. Teams that require a non-browser workflow should look elsewhere.
