The diagramThe spec
Create a swimlane process diagram for product returns across three lanes — Customer, Support Agent, and Warehouse
- Customer requests a return with the order number
- Support Agent validates the request against the return policy
- if ineligible, the agent notifies the customer and the process ends
- if eligible, the agent issues a prepaid label to the customer
- Customer ships the item
- Warehouse receives the item and inspects it
- if damaged beyond policy, Warehouse escalates back to the Support Agent for a partial-refund decision
- otherwise Warehouse restocks the item and Support Agent issues the full refund
- the customer receives a confirmation
Spec In, Diagram Out
Write the process. Get the swimlane.
Nine plain sentences naming three teams, their steps and their hand-offs — and out comes the cross-functional flowchart, lanes and decisions in place. Drag to compare.
Where It Earns Its Keep
Built for the work that decides what happens next.
Proposals & pre-sales
A principal-grade diagram for the deck — from the notes you already have, before the follow-up.
Process mapping
Multi-actor swimlanes from a plain description of who does what, when.
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.”

Common questions
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.
