Diagrams that work like you do

nifdi sorts the structure, so you can find your flow

Make a diagram

Cut through the noise. Structure your thoughts. Get more done.

Your team is overloaded and needs clear direction, so diagrams reduce cognitive load. You need an easier way to structure your thoughts, fast, so diagram the way you think best: generate or draw. And easily share your vision every time you update it: import and improve, then share in the format you need.

FAQ

What is nifdi?

nifdi is software for making diagrams.

nifdi is particularly good for software architecture diagrams, process flow diagrams, infrastructure maps, and anything else that has lots of structure and connections.

Why use nifdi instead of other diagramming tools?

nifdi uses a physical editing model: everything in your diagram behaves like a physical object that can be stacked, pushed and stretched. The model is easier, faster, and more fun than anything else you might have used.

What's more, the model is perfect for working with AI. Ask you AI to generate and edit, without giving up fine-grained control.

How do I get started using nifdi?

Just sign up with email, and you're good to go.

Is nifdi free to use?

Yes, nifdi's free tier makes unlimited powerful diagrams available to everyone. Check our Pricing page for the full feature list.

Do you have plugins / extensions / APIs?

Yes — the local MCP server is free and lets your AI agent create and edit diagrams locally on your machine. A hosted MCP and HTTP API for cloud diagrams are coming to Pro, so your agents can reach your diagrams from anywhere.
