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.

RenderMage is a browser-based AI architectural visualization studio for architects, interior designers, and students.

Users can describe changes in natural language, edit selected areas with inpainting, and choose photorealistic, watercolor, sketch, or Anime styles, as well as custom prompts and reference images. The browser workflow converts uploaded floor plan images into editable 3D wall layouts. Interior3D lets users place furniture, test materials, adjust atmospheres, and create interior concept visuals. RenderMage also offers architectural videos in 720p and 1080p, with a free upscaler to 4K. RM_Sync connectors are listed for SketchUp, Blender, and Archicad; other 3D tools can be used by uploading viewport screenshots. The free Studio plan includes 5 AI Credits.
