Stop writing system design documents from scratch. DesignCraftAI creates editable architecture diagrams and SRS from your idea or GitHub repo.
Built by a Senior Software Engineer for real-world projects.
Everything you need to design complete systems
From initial concept to detailed documentation, DesignCraftAI handles it all
Architecture Diagrams
AI generates visual system architecture with components, services, and connections. Fully editable with drag-and-drop interface.
SRS Documents
Comprehensive Software Requirements Specification automatically generated from your description.
API Specifications
RESTful API endpoints with export to Postman, Insomnia, OpenAPI, cURL, and more.
Database Schema
Entity relationships, tables, and data models designed for your system requirements.
How it works
From description to complete system design in minutes
Start Your Project
Two powerful ways to begin
Choose your preferred method: describe your system in plain English and let AI generate everything, connect your GitHub repository and let our AI analyze your existing codebase, or start with a blank canvas.
Start with a blank canvas
Create Blank Project
Full control over every component
Generate with AI
Describe your system in plain English and let AI create complete documentation
Import from GitHub
Connect your repository and AI analyzes your existing codebase
AI Generates SRS Document
Comprehensive requirements specification
DesignCraftAI analyzes your description and generates a complete Software Requirements Specification document with functional requirements, non-functional requirements, system overview, and more.
Architecture Diagram
Visual system architecture
See your system come to life with an interactive architecture diagram. Drag-and-drop components, services, databases, and their connections. Edit, add, or remove elements as needed.
Sequence Diagrams
Understand data flow
Visualize how different components interact over time. See the flow of requests, responses, and events between services, users, and external systems in detailed sequence diagrams.
API Specifications
RESTful endpoints ready to implement
Get complete API documentation with endpoints, request/response schemas, and authentication. Export to Postman, Insomnia, OpenAPI/Swagger, cURL, HTTPie, VS Code REST Client, or Markdown.
Database Schema
Data models and relationships
Generate entity-relationship diagrams and database schemas. See tables, columns, relationships, and data types designed for your system requirements.
Stay Synced with GitHub
Continuous updates from your repository
Connected your GitHub repository? Fetch the latest changes anytime and regenerate your documentation. As your codebase evolves, keep your SRS, diagrams, and API specs up-to-date with a single click.
