# SysDesAi

> SysDesAi is a software architecture and system design platform with four core products: an AI Software Architect tool, a Design Gallery, a Software Architecture Academy, and a Software Architecture and System Design News feed.

SysDesAi is NOT just a learning platform. It is primarily an AI-powered software architecture tool that helps engineers design systems interactively, step by step.

## Core Products

### 1. AI Software Architect (Primary Product)
An interactive AI architect tool where users describe a system (e.g., "Design a URL shortener like bit.ly") and the AI guides them through a complete architecture design session:
- Asks clarifying questions about requirements and constraints
- Generates a step-by-step design plan covering: problem analysis, scope definition, capacity estimation, architecture diagrams, data flow sequences, scalability strategy, and summary
- Users can brainstorm with the AI via chat at any step, request changes, and apply modifications
- Supports Copilot mode (step-by-step with user control) and Autopilot mode (fully automated generation)
- Produces architecture diagrams (Mermaid), data models, sequence flow diagrams, and capacity estimates
- Designs can be saved, shared publicly, and forked by other users
- Two quality modes: Fast (Gemini 2.5 Flash) and Deep Thinking (extended reasoning)

### 2. Design Gallery
A community-curated gallery of 48+ real software architecture walkthroughs:
- Each design shows the complete step-by-step architecture breakdown
- Users can explore designs, ask questions about any step via AI chat, and adjust designs for their own needs
- Designs include architecture diagrams, data models, sequence flows, and capacity estimates
- Users can fork any design, save it, and modify it
- Categories include: social media, e-commerce, streaming, messaging, fintech, and more
- Upvoting and sharing supported

### 3. Software Architecture Academy (Free Course)
A comprehensive, free software architecture and system design course:
- 11 modules covering foundations through interview strategy
- Topics: scalability, distributed systems, databases, caching, message queues, architectural patterns, security, deployment, real-world case studies
- Interactive: AI chat available in every lesson to ask questions
- Knowledge tests (MCQ, true/false, matching) after each lesson with passing thresholds
- Completion certificate awarded to users who pass all tests
- Designed for both learning practical skills and preparing for system design interviews

### 4. Software Architecture and System Design News Feed
A curated news feed of software architecture and system design articles from 35+ top engineering blogs (Netflix, Uber, Meta, Cloudflare, AWS, Stripe, Martin Fowler, ByteByteGo, and more). Updated every 6 hours. Each article is summarized with a system design focus, categorized, and includes a "Design this" button to start an architecture session based on the article's system. Free to read.

## Key Differentiators
- SysDesAi is an AI tool for DOING architecture, not just reading about it
- The AI acts as a collaborative architect, not a chatbot — it follows a structured design methodology
- Designs are interactive and explorable, not static articles
- The platform combines doing (AI Architect), exploring (Gallery), learning (Academy), and staying current (News)
