About Eler

Both my parents are architects. My dad runs an interior and hospitality design studio, Belenko Design, that delivers projects turn-key, so I grew up around client decks, renders and deadlines.

In late 2025 I was building a small CAD tool for a friend studying architecture. One day I took a screenshot of a house I'd modeled and ran it through an image model to see how it would look rendered. I showed it to my dad. He said it was the tool he'd been missing: he already used AI for client decks, but couldn't get pictures that looked good, matched the idea, and stayed true to the geometry, all at once. I spent the next weeks digging into the problem, and it became Eler.

Architects and interior designers who juggle AutoCAD, Adobe and a handful of other apps, and wait days on contractors for renders that still look like renders. Eler is meant to get you to something that looks like a photo, fast enough that you keep iterating instead of settling.

• Start from your real model. Upload SketchUp, FBX, 3DS or GLB as it is, with nothing to export or convert.
• Renders that respect your geometry, with views that stay consistent with each other.
• Edits in plain words that keep the rest of the picture intact. Change the couch or the lighting in a minute, not a day of back-and-forth.

AI rendering still has its quirks. But it frees the imagination of whoever is using it, and it makes iterating far faster. I think it's the future of how spaces get designed, and building it is genuinely exciting.

I'm Constantine Belenko (Kostiantyn Bielienko on paper), from Odesa, Ukraine. I've worked as a software engineer since I was a teenager, most recently in DevOps. When the war started I moved to Barcelona to study, then to the US. Eler started in a warehouse in San Francisco's SoMa that friends and I run as a co-working space.
