I Built an AI System Design Generator — Here’s How It Works (ArcMind AI)

ArcMind AI — Generate Complete System Designs Using AI

System design is hard.

You sit down to design a scalable architecture, and suddenly you’re drowning in:

  • choosing the right components
  • planning microservices
  • deciding databases
  • drawing architecture diagrams
  • explaining everything clearly

I’ve gone through this pain myself while building products and preparing for system design interviews.

So I created ArcMind AI — an AI-powered system design generator that converts plain English descriptions into fully structured architectures.


What ArcMind AI Does

Just describe what you want to build, and it generates:

✔ Full System Architecture

Clear explanations of:

  • API gateway
  • backend services
  • databases
  • caching
  • load balancers
  • queues
  • messaging systems
  • CDN
  • authentication
  • deployment strategy

✔ Component Breakdown

Every part of the system explained with responsibilities.

✔ Recommended Tech Stack

Based on scale + use case:

  • databases
  • queues
  • frameworks
  • cloud services

✔ Sequence Flows

Clear descriptions of how operations flow through the system.

✔ Diagram Output (SVG/PNG Coming Soon)

Visual architecture that you can export and share.


Why I Built ArcMind AI

I kept noticing:

  • Developers waste hours on diagrams
  • Interview prep is stressful
  • Architects manually repeat similar designs
  • Startups need quick architecture drafts
  • Students struggle to structure their ideas

System design is a bottleneck.

AI can fix it.

I wanted a tool where you just describe a system like:

“Build me an Instagram-like app with messaging, feed, notifications, and analytics.”

And it instantly gives you production-ready architecture.


How It Works (High-Level)

ArcMind AI is powered by:

  • Google Gemini models
  • LangChain for structured reasoning
  • Dynamic prompting with context injection
  • Node.js backend
  • Next.js frontend
  • Diagram generation logic

The AI breaks your description into multiple layers:

  1. Core features
  2. Functional requirements
  3. High-level architecture
  4. Microservices decomposition
  5. Database schema ideas
  6. Scaling strategies
  7. Tech stack
  8. Visual architecture diagram

Then returns everything in a clean, human-readable format.

Use Cases

  • System design interviews
  • Architecture planning
  • Startup MVP planning
  • Technical documentation
  • Client proposals
  • Internal engineering discussions

You get a simple input box → describe your system → get your architecture instantly.

💬 I’d Love Your Feedback

Tell me:

  • What feature should I add next?
  • Do you want templates (Uber, Netflix, ChatGPT, etc.)?
  • Should I add PDF export / Notion export / GitHub README export?

Feel free to drop suggestions below — I’m building this solo and shipping fast.

Thanks for reading!
