Turn ideas into architecture diagrams for teams and agents

Describe your system by voice. Lycana turns it into a typed architecture diagram, capturing your reasoning as you explain it. Teammates and AI agents can look up what each part does and why it's there, then build on the plan with your intent in mind.

Hey Product Hunt👋
I'm Jensen Huang (prev ByteDance, Razer) and I'm building Lycana with Justin, my cofounder (prev UC Berkeley (Morphing Matter Lab), dConstruct robotics, Fabrica AI).
Coding agents write code well, but they guess at how your system fits together. You describe the architecture in a prompt, the agent fills the gaps, and three files later you find out it treated the queue as a database.
Lycana draws the diagram while you describe your system out loud.
What makes it different
- Voice-first approach You don't type a prompt or learn a syntax. Say "the API writes to Postgres and pushes jobs onto a queue" and the nodes appear while you're still speaking.
- Every part has a type. Each node records what it is, such as a service, database, cache or queue, and each link records what flows across it. When you say "the queue", Lycana changes the queue node.
- Edit by voice or by hand. Drag a node, rename a link, or say "put the cache in front of the API". Both change the same diagram.
- It asks when a command is unclear. If Lycana can't tell which node you mean, it asks you which one.
- Export it. Download the diagram as PNG, JPG, PDF or Mermaid.
- MCP support is coming soon. Your coding agent will be able to query your diagrams directly and read each component, its type and what it connects to.
Lycana is free to try with no signup.

We'd like to know one thing. Was Lycana faster than your usual sketch or your usual architecture prompt? We're replying here all day, and you can also email humans@lycana.ai.
