Fenestra
AI architectural rendering from sketch, CAD & 3D, in your browser.
Fenestra is a solid, affordable choice for architects who want sketch-to-render speed without juggling multiple AI tools. Its curated model selection and editing controls are genuinely useful for archviz, and the credit system works for moderate use. Heavy users should watch credit costs; if you need unlimited credits, look at Vizcom or similar alternatives.

Skip Fenestra if you need unlimited credits for high-volume production, or if you require team collaboration, custom API access, or fully offline rendering—those are capped, coming soon, or unavailable.
Credits reset monthly, so if you run out mid-month you'll need to buy an add-on pack or wait—no rollover.
Fenestra's pricing fits students, solo designers, and small studios with moderate rendering needs—Individual at $8/month (yearly) is cheaper than Vizcom's $39/month pro tier, and Pro at $28/month undercuts Midjourney's $30/month for similar credit allowances. Heavy users should compare per-credit costs with Vizcom's unlimited offerings.

About Fenestra
Fenestra is a browser-based AI rendering platform made for architects, interior designers, and visualization pros who need to turn sketches, CAD drawings, photos, and 3D models (FBX, GLB, 3DM) into photorealistic renders and animations quickly—without learning new software. It uses natural language prompts and hand-selected AI models to streamline the whole concept-to-presentation workflow. The platform is built around four core modes: Create, Edit, Enhance, and Animate. Create transforms sketches, elevations, and 3D models into photorealistic visuals, while Edit lets you add or remove objects, change materials, and modify facades with text commands—recently upgraded with rectangle select and hand-drawn masks. Enhance sharpens and upscales images, and Animate adds cinematic motion to your renders, with video generation powered by models like Seedance 2.0 and LTX 2.3. Fenestra curates 19 AI models—including Nano Banana 2, GPT Image 2, Flux 2 Pro, Seedance 2.0, and LTX 2.3—so you can pick the best one for architecture, editing, styles, or video without juggling multiple tools. Outputs scale up to 8K, and the system is designed for architects: you can import PDFs, use custom style references, and choose from new hand-drawn drawing styles (marker, crayon, ink, pastel, stipple, pencil). Pricing is credit-based: roughly 1 credit per render, 2 for enhancements, and 10 for videos. Plans start at $8/month (Individual, billed yearly), with about 200 credits per month. Your content stays private—Fenestra doesn't train on your data. It's used by over 20,000 architects and designers, with more than 200,000 images generated. Compared to general AI image tools, Fenestra is purpose-built for architecture, offering a single, curated workflow with real editing control and commercial use rights on paid plans.
Behind the Verdict
When you're an architect or interior designer drowning in renders that take hours, Fenestra's browser-based workflow is a relief. You upload a sketch, type a prompt, and get a photorealistic image in seconds—no new software, no training. The credit model (about 1 credit per render, 2 for enhancements, 10 for videos) is transparent, and the $8/month Individual plan is cheap enough for students. But it's not for everyone. We'd reach for Fenestra when you're iterating on concepts, updating facades for marketing, or creating client visualizations quickly. The Edit mode is the real differentiator: rectangle select, hand-drawn masks, and natural language commands let you adjust specific areas without redoing the whole image. Recent changelog entries—like the scroll-video maker and PDF import—show the team is actively building for real workflows. Where it bites: credit costs add up if you're generating a lot of videos or enhanced renders. The Pro plan's ~500 enhanced renders per month might not be enough for a busy studio. Also, team features like shared credit pools are only on the Team plan (5 seats, $208.33/mo yearly), and some features are still 'coming soon'—like custom AI model training and 3D model generation. Compared to alternatives like Vizcom, which offers unlimited credits, Fenestra is cheaper per credit at higher tiers but caps your monthly volume. If you need unlimited iterations, Vizcom might be better. If you want a curated model selection and don't want to pay for unused capacity, Fenestra's tiered credits are more straightforward. In practice, Fenestra delivers on its promise of 'from sketch to presentation' with minimal friction. The model choice—Nano Banana 2 for architecture, Seedance 2.0 for video—is smart, and the privacy stance (no training on your

Real-world workflow fit
Concrete scenarios for the personas Fenestra actually fits — and what changes day-one when you adopt it.
You have a hand-drawn sketch of a facade and need a photorealistic render for a client presentation.
Outcome: Upload the sketch, choose a model like Nano Banana 2, type a prompt describing materials and lighting, and get a high-quality render in seconds. Use Realtime mode to tweak and see updates instantly.
You need to restage a room's furniture in a render.
Outcome: Use Edit mode with a rectangle select to mask the area, then prompt 'replace sofa with modern leather version'—the rest of the image stays untouched.
You want to animate a static render into a cinematic walkthrough for a client.
Outcome: Use Animate mode with Seedance 2.0 to generate a 10-second clip with camera motion, or use the scroll-video maker to create a frame-by-frame scroll animation and share a link.
Use Cases
- Transform a hand-drawn sketch into a photorealistic architectural render in seconds.
- Import an FBX 3D model and generate cinematic exterior views with custom lighting and materials.
- Edit a rendering by typing 'replace the sofa with a modern leather version' and get instant results.
- Enhance a low-resolution client render to 4K with added detail for presentation.
- Create a 10-second cinematic walkthrough from a single render for client presentations.
- Apply a signature style to all images in a project for a consistent visual theme.
- Turn a PDF floor plan into an interior render without exporting to image first.
- Build a scroll-driven animation from renders to share a link with clients.

Limitations
- Pricing plans limit monthly credits (e.g., Individual plan 200 credits/month, Pro 1000, Studio 2000), with each render ~1 credit and each video ~10 credits.
- Team tools and 3D model sharing are marked 'coming soon' in pricing.
- Real-time AI rendering is in alpha, so stability and quality may vary.
