RNDRS Launches: Node-Based AI Rendering Built for Architects

Today, RNDRS opens to everyone. -Pronounced Renders- After months in private testing with architects, interior designers and visualization studios, our node-based AI rendering platform is live — and free to try with 3 renders, no card required.

RNDRS turns the slow, expensive part of design communication — making the image — into a step measured in seconds. Upload a sketch, a SketchUp or Rhino viewport export, or a photo; prompt the look you want; and get a photorealistic render that respects the geometry you actually drew. Then keep going: erase, restyle, upscale to 4K, and animate — all on one canvas.

Why we built it

Photorealistic imagery has always sat at the wrong end of every design timeline. It cost hours or hundreds of dollars per frame, so practices rendered the one option they'd already decided on — and showed clients a choice between a single image and several paragraphs of description. People don't approve descriptions. They defer.

The first wave of AI rendering tools made single images cheap, but treated rendering like a slot machine: upload, prompt, pray, repeat. Geometry drifted. Windows multiplied. There was no way to compare options, to build on a good result, or to carry one render through to a finished deliverable.

We thought rendering should be a workflow, not a single lucky shot. So we built RNDRS around a node canvas.

What makes RNDRS different

• Node-based by design. Wire one model export into three render nodes to compare claddings side by side. Chain an AI eraser before the render, push the winner through the 4K upscaler, and end on an image-to-video node for the closing slide. The canvas isn't complexity you pay upfront — it's capability that appears the moment you iterate.
• Geometry preservation first. We tune hard for the thing architects care about most: your massing, your fenestration, your proportions survive the render.
• A full pipeline, not a single tool. Render, erase, virtual staging, upscaling and video live in one place, so a concept image and a client-ready deliverable come out of the same session.

Who it's for

RNDRS is built for the people who make design legible to clients and stakeholders:

• Architects turning early sketches and working models into concept imagery.
• Interior designers staging and restyling spaces per client and per buyer profile.
• Masterplanners and landscape architects rendering site options, planting character and phasing at speed.
• Visualization studios running fast option studies before committing to a single commissioned final.

Pricing

Plans start at $29/mo, and every new account gets 3 free renders to try the full workflow before paying anything. No credit card to start.

Where we're headed

This launch is the foundation, not the finish line. Over the coming period we're focused on:

• Deeper model fidelity — sharper geometry preservation and more controllable materials, lighting and camera.
• Richer collaboration — shared canvases and project spaces so teams can iterate on the same boards together.
• Plugins and pipeline integrations — tighter bridges from SketchUp, Rhino and Revit straight onto the canvas.
• Expanded video and motion — longer, more controllable image-to-video for walkthroughs and presentation closers.
• More languages — RNDRS is rolling out across multiple languages so the workflow meets practices where they work.

We're building this with the people who use it. If you're an architect, designer or studio with a workflow that AI rendering should fit but doesn't yet, we want to hear about it.

Start with 3 free renders — upload a sketch and build your first chain. Sketch → render → 4K takes about two minutes, including the signup.
