Rebuilding the tools the built world runs on.
Ploterr started with a simple frustration: deciding what to build shouldn't take longer than designing it. We're a small team making site feasibility, floorplanning and documentation feel like one fast, honest workflow.
Architecture deserves better than 40-year-old software.
The people shaping our cities still spend their days fighting the tools meant to help them. Feasibility lives in one app, floorplans in another, documentation in a third — and every handoff quietly drops context. A confident go/no-go takes weeks, then the same project gets redrawn from scratch as it moves downstream.
We think that's backwards. Decisions about what gets built should be fast, traceable, and reversible. The work you do early should follow you forward instead of starting over. And the files you create should belong to you — not to a vendor's proprietary format and per-seat license.
So we're building Ploterr: one workflow that carries a project from site feasibility through floorplans to documentation, with AI taking the grind and your team keeping the judgement. It's built on OpenGeometry, our open geometry engine — because the foundation of the built world shouldn't be a black box.
Six principles, set in stone.
They're not marketing lines. They're the rules we hold every release against.
Open by default
Export everything, anytime, with no lock-in.
Speed is the point
We optimize relentlessly for momentum.
AI does the grind
Repetitive work automated, judgment stays human.
One continuous workflow
Early decisions follow the project forward.
Built with practitioners
Shaped by architects, not just engineers.
Honest about what we are
What helps today, and what is still in progress.
A small team, building in the open.
No bloated org chart, just a focused group inside OpenGeometry who care a lot about how the built world gets designed.

Founder“I've watched too many good projects stall in clunky, disconnected software. Ploterr is the tool I wished existed. Fast, open, and built for the way design actually happens.”
Ploterr is a product of OpenGeometry, an open geometry engine for the built environment. We build in the open because the foundation of how cities get designed shouldn't be locked inside a black box. Ploterr is what that engine looks like in the hands of a working design team.
