AI ER Diagram Generator Netflix architecture example Architecture library

How it works

  1. Describe the system (components, flows, constraints).
  2. Dashin generates a diagram you can understand immediately.
  3. Edit, iterate, and share when it looks right.

Example prompts

"Design a Netflix-like streaming architecture: clients, API gateway, auth, playback service, personalization, CDN, origin storage, encoding pipeline, observability."
"Create a payments flowchart: checkout → payment intent → 3DS → webhook confirmation → order fulfillment. Include failure paths and retries."
"Generate a sequence diagram for user signup: client → auth service → email verification → profile service → analytics event."
"Create an ERD for ecommerce: users, products, orders, order_items, payments, shipments, coupons. Add 1:N and N:M relationships."

What you can generate

  • System architecture diagrams (services, data stores, flows)
  • ER diagrams (tables, keys, relationships)
  • Sequence diagrams (request/response steps)
  • Flowcharts (processes, decisions, loops)

FAQ
Do I need to know Mermaid? No—start in English. If you know Mermaid, you can still use it, but it’s optional.
Can I iterate? Yes—ask for changes like “split service”, “add cache”, “add retries”, “add join table”.
Can I share? Yes—publish links so teammates can view and remix.
