Fenestra vs Gendo

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.

Gendo is a web-based collaborative canvas for architectural visualization. Architects and designers can generate renders from sketches, change materials, populate scenes, transfer styles, enhance images, and upscale renders to 4× resolution. Its natural-language assistant can use workspace tools, and teams can run simultaneous generations, share images, add comments and notes, and iterate together. Users bring scenes or views into the canvas by exporting them; direct plugins for Revit, SketchUp, and Blender are on the roadmap. The free plan includes Material Bank material specification, but its prompts and outputs are not treated as confidential. Studio and Enterprise prompts and outputs are contractually protected from AI training and marketing use. Gendo says data is stored in EU data centres, encrypted at rest with AES-256 and in transit with TLS. Free costs nothing; Studio costs £66 a year, billed annually at £66/mo (£790/year; excl. tax).
