Open a page of possibilitiesA person opens an oversized sketchbook as colorful ideas rise from its pages.

Turn ideas into architecture diagrams for teams and agents

Describe your system out loud. Lycana draws it as a typed diagram you can keep editing.

See how Lycana works

Describe

Tell Lycana what you are building in plain language. Start with a sentence, a rough idea, or a change you want to make.

Begin with the thought.
Speak an idea into a system diagramA person speaks beside a laptop while three colored thoughts travel toward connected system cards.

Structure

Lycana turns the idea into components, relationships, and data flows you can see, rearrange, and understand.

See the whole system.
Loose ideas becoming a structured systemA person types while colored fragments organize into three diagram boxes.

Refine

Move anything yourself or ask for a change. Lycana redraws the system without taking the canvas away from you.

The canvas stays yours.
Refine a system by handTwo hands arrange colorful paper pieces on a work sheet beside a ruler and eraser.

Delegate

Let Claude Code, Cursor, or Codex draw for you. Your agent maps your system onto the canvas, and its changes wait for you to accept them.

Draw alongside your agent.
Connect an agent
A coding agent's commands land on the canvas one by oneA terminal on the left asks the agent to map the repo into Lycana, then lists what it does: read diagram Checkout, add node queue, add link api to queue, add node worker, and add boundary async jobs. On the canvas to the right, beside the user's nodes web and api, a dashed outline marks what it read, the queue and worker nodes appear linked below api, and a dashed boundary named async jobs gathers them. Dotted arrows run from the terminal lines to the nodes they made.webapi› map this repo into lycana◇ read diagram "Checkout"+ node queue+ link api → queue+ node worker▢ boundary "async jobs"queueworkerasync jobs
