Fenestra vs Renderica

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.

Renderica uses AI to turn architectural sketches and plans into photorealistic renders. It extracts room dimensions and openings from a plan and conditions rendering on that geometry. Inputs include PDF, DXF, PNG, JPG, GLB, and GLTF files, as well as hand-drawn sketches, floor plans, CAD sketches, and Pinterest image URLs. The homepage lists compatibility with Revit, SketchUp, ArchiCAD, Rhino 3D, AutoCAD, Blender, 3ds Max, and Chief Architect. Users can select from 32 style presets and five lighting modes, provide Pinterest pins or image URLs as style references, and share a client review link or export a 4K PNG from the gallery. The Free plan costs nothing and includes three renders per month at 1024px; Starter costs $24 a month for 60 monthly renders at 2048px. Pro costs $59 a month and Studio costs $179 a month. Renderica says uploaded content is not used to train its own models. Its policy describes some stored assets as accessible through non-expiring unauthenticated URLs and is marked draft pending legal review. For non-rectangular rooms, openings may not be carved and angled walls may be omitted.
