Solution design
Turn a rough solution description into the target architecture your team can align on.
For solution architects, analysts & consultants
Describe your system. The diagram draws itself.
Swimlanes, flowcharts, architectures, ER models — described in plain words, drawn in the notation your reviewers expect, editable the moment you disagree with it.

Where it earns its keep
Built for the work that decides what happens next.
02
Proposals & pre-sales
A principal-grade diagram for the deck — from the notes you already have, before the follow-up.
03
Process mapping
Multi-actor swimlanes from a plain description of who does what, when.
04
Documentation
Give every system a picture of how it works today, editable as things change.
How it works
Three steps. Zero manual drawing.
01
Describe the system
Type it in plain words — or paste a design doc, requirements, notes. TXT, PDF, DOCX, and more.
02
Watch it draw
The diagram streams in live as the AI places systems, connects flows, and labels every edge.
03
Refine and share
Edit directly on the canvas, then export to draw.io, PNG, or a shareable HTML file.
“I spent years redrawing the same boxes after every design discussion. DiagramThis is the tool I wished I had — describe the system once, and the boxes draw themselves before the follow-up email goes out.”

Stop dragging boxes.
Start describing systems.
You can already describe the system in plain words. DiagramThis turns that into the diagram that usually costs you the rest of the afternoon.
