Archome AI vs Harth

Archome AI turns listing photos, sketches, CAD screenshots and plans into photorealistic architectural renders, with renders described as taking about 30 seconds. Its structure lock keeps massing, openings, proportions and camera fixed during image-to-image work while materials, lighting and atmosphere change. Tools cover interiors, exteriors, sketch-to-render, plans, masterplans, materials, inpainting, landscapes, detail, 2D-to-3D, video and upscaling. The service runs in a browser without a local installation or GPU. Free plugins connect it to SketchUp 2021 and newer and Rhino 7 or 8 on Windows and macOS; the 3ds Max 2021-and-newer plugin supports Windows. A public REST endpoint accepts a base64 PNG, tool and prompt, then returns a render URL. API calls share the web app's credit balance, image data is limited to about 10 MB, and calls are rate-limited. The free trial includes 100 credits for three renders. Paid options include a 15.00 USD one-time Starter Credit Pack and monthly plans, including Lite at $29 a month and Plus at $49 a month. Paid packs and plans list commercial-use rights.

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.
