Archome AI vs Fenestra

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.

Fenestra is a browser-based studio that turns architectural sketches, CAD drawings, photos, and 3D models into renders and animations. It accepts prompts and uploads including JPG, PNG, WEBP, PDF, GLB, FBX, and 3DM, with workflows for Revit, Rhino, and SketchUp. Users can create, edit, enhance, and animate designs through natural-language prompts and cinematic presets. Realtime image generation runs at 15+ FPS while the camera, prompts, or styles change. Its Video tool turns a still render, sketch, or photo into a flythrough using pan, dolly, or orbit moves. The homepage advertises 71 AI models for image, editing, and video work. Fenestra runs entirely in a browser without a plugin, render-engine setup, or dedicated GPU. A free plan is available; Individual costs $8 a month when billed yearly, with 200 credits monthly. Pro, Studio, and Team add credits and collaboration features, while Enterprise uses unlisted pricing. Pro, Studio, and Team are private by default, and Fenestra says it does not train on customer data.
