Design systems with an AI architect, explore real architecture walkthroughs, stay current with curated news, and master system design with an interactive course.
AI Software Architect
Describe any system and your AI architect guides you through the complete design — step by step. It asks clarifying questions, generates architecture diagrams, data models, sequence flows, and capacity estimates. Chat at any step to brainstorm, request changes, or explore alternatives.
- Interactive chat — ask questions, request changes at any step
- Copilot mode (step-by-step) or Autopilot mode (fully automated)

How the AI Software Architect Works
Describe Your System
Enter a system description like "Design a URL shortener" or "Design a messaging app like WhatsApp."
Answer Questions — or Let Autopilot Decide
The AI asks about requirements, scale, constraints, and priorities. Answer them yourself in Copilot mode, or switch to Autopilot and the AI makes reasonable assumptions, answers its own questions, and drives the entire design process for you.
Full Design Generated Automatically
The AI generates each design phase: problem analysis, scope, capacity estimates, architecture diagrams, data flows, and scalability strategy. In Autopilot mode, all steps are generated back-to-back — you get a complete design without lifting a finger.
Iterate, Refine & Share
Review the generated design and chat with the AI at any step to ask questions, request changes, or explore alternatives. Iterate until you're satisfied, then save your design, share it publicly, or fork existing designs from the gallery.
Frequently Asked Questions
SysDesAi is an AI-powered software architecture and system design platform. Its core product is an AI Software Architect that guides you through designing systems step by step — from clarifying requirements to generating architecture diagrams, data models, sequence flows, and capacity estimates. It also includes a gallery of 48+ explorable architecture walkthroughs and a free interactive course with tests and certificate.
You describe a system (e.g., "Design a URL shortener like bit.ly") and choose your mode. In Copilot mode, the AI asks clarifying questions and you guide each step. In Autopilot mode, the AI makes reasonable assumptions, answers its own questions, and generates the entire design for you — problem analysis, scope, capacity estimates, architecture diagrams, data flows, and scalability strategy — all automatically. Either way, you can chat with the AI at any step to iterate, request changes, or explore alternatives.
The Design Gallery contains 48+ community-contributed software architecture walkthroughs. Each design shows the complete step-by-step architecture breakdown with diagrams, data models, sequence flows, and capacity estimates. You can explore any design, ask questions via AI chat, fork it to create your own version, and customize it for your needs.
The Software Architecture Academy is a free, comprehensive course covering software architecture and system design — from fundamentals to distributed systems and interview strategy. It includes 11 modules with 60+ lessons, interactive AI chat in every lesson, knowledge tests (MCQ, true/false, matching), and a completion certificate for users who pass all tests.
The Software Architecture Academy course and Design Gallery are completely free — no credits, no limits. New users also get 50 free credits for AI architect sessions. If you bring your own API key (Google Gemini or Anthropic Claude), AI design sessions are entirely free with no credit cost at all — unlimited designs, unlimited chat, zero cost. Credit packs start at $5 for users who prefer not to use their own key.
Yes. SysDesAi is widely used for system design interview prep. The AI architect simulates a real design interview by asking clarifying questions and guiding you through the design process step by step. The Academy includes a dedicated Interview Strategy module, and the Gallery contains real-world design examples commonly asked in FAANG and tech interviews.
SysDesAi News is a curated feed of software architecture and system design articles from 35+ top engineering blogs — Netflix, Uber, Cloudflare, Stripe, AWS, Martin Fowler, ByteByteGo, and more. Every 6 hours, new articles are automatically fetched, filtered for relevance, and published with rich summaries. Each article includes a "Design this" button that pre-fills the AI architect with a related system design prompt. The news feed is completely free to read.
