Gendo vs RenderAI

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).

RenderAI is a browser-based service for turning sketches, drawings, 3D models, and photos into photorealistic renderings at 4K or higher. It is aimed at architects, interior designers, product designers, and engineers. Users can animate generated images into AI videos, with choices for resolution, duration, and token use. Project Boards offer a shared canvas for comparing renders, arranging moodboards, and preparing client presentations. For CAD work, the service accepts screenshots or JPG and PNG exports from Revit, Rhino, Vectorworks, Archicad, SketchUp, and AutoCAD; it can also post-produce, upscale, and animate renders from Enscape, D5 Render, and Twinmotion. Uploads can be JPG, PNG, WebP, or HEIC, up to 5MB. It runs in a browser, needs an internet connection and a Google or Microsoft account, and requires no software download. The limited free plan requires no credit card; paid plans start at $13/mo. Tokens expire at renewal or when a subscription is paused or canceled, and do not roll over.
