Text to diagram
Describe the system in plain language and Lyra drafts a first version on the canvas in seconds.
AI diagram generator
Describe your system in words. Lyra drafts the diagram.
Write what your system does in plain language and Lyra AI drafts a first version of the diagram. Then you refine it on the infinite canvas: move nodes, keep arrows attached, place official cloud icons, collaborate in real time and export to Mermaid.
Text to diagram · Six languages · Mermaid export
It drafts, you refine
Every node stays editable: move it, retype it, reconnect it, and arrows follow the nodes.
Official cloud icons
Lyra can place icons from a 726-icon set covering AWS, Google Cloud and IBM Cloud.
How it works
An AI draft is a starting point, not a finished diagram
Lyra gets the structure onto the canvas fast, so your time goes into the decisions instead of dragging boxes around.
Start from a description
plain language
Write a paragraph about your services, flows or steps and Lyra drafts the nodes and connections for you.
Refine by hand
you stay in control
Edit any node, rearrange the layout and connect what Lyra missed. Arrows stay attached as you move things.
Works in six languages
es, en, de, fr, it, pt
Write your prompt in your own language and keep working in the same interface.
Share and export
with the team
Open a live session, keep version history, share by link and export to PNG, JPG, PDF or Mermaid.
What you can generate
Cloud and system architectures with official service icons.
Flowcharts and process steps from a written description.
Service maps with queues, caches and databases.
First drafts you then rearrange and connect by hand.
Diagrams from prompts written in any of the six supported languages.
