Fenestra

Fenestra is a web-based AI rendering platform for architects, interior designers, students, and studios that converts sketches, CAD drawings, photos, and 3D models into presentation-ready visuals in seconds.

Key capabilities include:

• Sketch, CAD, and 3D to render: generate photorealistic architectural images from sketches, elevations, 2D CAD drawings, and 3D files (including FBX, GLB, 3DM).
• Edit and iterate with natural language: add or remove elements (people, furniture), modify facades, and refine compositions using AI-assisted prompting and image editing.
• Enhance and upscale: sharpen existing renders and increase detail with one-click enhancement.
• Animation output: create cinematic animations from generated images using presets (plan-dependent).

Pricing: Freemium & Pay-As-You-Go; includes 5 free signup credits. Subscriptions are currently 50% off: Individual ($10/mo), Pro ($35/mo), Studio ($60/mo), and Team ($250/mo). One-off Top-Up Credits (non-subscription) are available starting at $18.99.

What makes it notable: it runs entirely in the browser with no specialized hardware, supports unlimited projects and revisions on paid plans, offers commercial licensing for client presentations and marketing, and provides team credit pools with priority support. Custom AI models are available for firm-specific styles on higher-tier plans.
