Stencils and templates
Five stencil sets with 25 shapes (flowchart, network, org, process, infrastructure) and nine templates.
Productivity
Diagrams that lay themselves out.
An original SVG diagram editor with stencils, auto-layout, swimlanes, and shapes linked to your data, exported to SVG or PNG.
What you get
Auto-layout
Top-down or left-to-right layouts with crossing reduction; connectors route around shapes.
Groups and swimlanes
Nested containers and vertical or horizontal lanes, with full undo.
Data-linked shapes
Link shapes to a CSV and preview each refresh, which rolls back if verification fails.
Agent actions with approvals
Agents can create diagrams; deletes wait for your approval and are audited.
Live co-editing
Real-time collaboration on one diagram.

Questions
Can I export?
Yes, to SVG and PNG, using the same geometry engine as the editor.
Does it import Visio files?
Not yet. It is an original editor, not a Visio clone.
How much does it cost?
Every plan and price is on the pricing page.
Part of one subscription.
