Why We Built Petrograph: A Miro Replacement for the AI Era

After ten years of using Miro for virtual whiteboarding and diagramming, I hit a wall. Like most SaaS products that measure success by feature count, Miro had become bloated with so many "features" that it killed the productivity of the tools I actually needed. So we built Petrograph.

The Miro Problem

Miro started simple. Draw shapes, connect them, organize ideas visually. It worked. But over the years, every product update added more complexity. Collaboration features I didn't need. Templates for industries I wasn't in. Integration widgets that cluttered the interface.

The core drawing tools—the reason I used Miro in the first place—got buried under layers of product management decisions. What used to take three clicks now took seven. Keyboard shortcuts got reassigned to new features. The thing that made me productive disappeared under the weight of everything else.

But the bigger problem was AI. I needed my diagrams to talk to Claude, to iterate on architecture designs, to generate new versions based on feedback. Miro wasn't built for that world.

Building for Speed and AI Integration

Petrograph was the first real software we designed and built that wasn't a typical click-and-type web application. It has drawing features, keyboard shortcuts, and interactions all designed around one goal: making diagram creation fast and actually fun.

The AI integration was non-negotiable from day one. Petrograph exports diagrams as clean JSON. I can take that JSON into a Claude session, work through architectural problems, generate improvements, and import the updated JSON back into Petrograph. The diagram updates to reflect the AI's suggestions.

This isn't a gimmick. It's how I actually work now. Draw the initial architecture in Petrograph, export to Claude for optimization, import the results, and see the updated design immediately. The whole cycle takes minutes, not hours.

What We Kept, What We Threw Away

We kept everything that makes diagramming productive. Fast shape creation. Intuitive connecting. Keyboard shortcuts that actually make sense. Clean visual hierarchy.

We threw away everything else. No collaboration features that slow down individual work. No template marketplace. No integration widgets. No features built because competitors had them.

The result is a tool that does one thing extremely well: helps you think through complex systems by drawing them, then iterate on those drawings with AI assistance.

The Real Test

I've been using Petrograph for every architecture diagram since we launched it. System designs, workflow maps, data flow diagrams. The JSON export to Claude workflow has become standard practice for any complex project.

The speed difference is real. What used to take an hour in Miro now takes fifteen minutes in Petrograph. Not because we cut corners, but because we cut everything that wasn't essential to the core task.
