Architecture Diagram Generator
AI architecture diagrams from plain English. Describe your diagram in plain English below — free, no account needed. Output stays editable as draw.io XML and can be exported as SVG or PNG after signup.
Export anywhere
Copy the draw.io XML and import it into diagrams.net, draw.io desktop, or Confluence.
Edit visually
Click "Save & Edit Diagram" to open the result in AIDrawIO — drag, restyle, and re-prompt with better models.
Upgrade for more
Free tier: Gemini Flash, 5/hour. Sign up for GPT-5, Claude, unlimited, SVG/PNG export.

ExampleThree-tier web app with React frontend, Node.js API, Postgres database, Redis cache, and an S3 bucket for uploads.
When to use this tool
Use it when you need a fast software architecture overview for design docs, onboarding, or stakeholder reviews.
Use it for cloud and application diagrams that need services, boundaries, and data flow shown clearly in one view.
Use it when you want a prompt-first draft that can still be refined later in draw.io or diagrams.net.
Example prompts
Prompt 1
Three-tier web app with React frontend, Node.js API, Postgres database, Redis cache, and an S3 bucket for uploads.
Prompt 2
Microservices platform with React frontend, API gateway, auth service, billing service, notification service, Postgres, Redis, and Kafka.
Prompt 3
SaaS analytics architecture with Next.js app, Python API, background workers, ClickHouse, object storage, and a data ingestion pipeline.
Prompt 4
Cloud-native architecture for a document processing system with upload service, queue, OCR workers, vector store, and audit logging.
Prompt tips that improve results
Name the main actors, services, systems, or tables instead of describing the diagram vaguely.
Include boundaries, traffic direction, failure paths, or data stores when those details matter to the audience.
After generation, use a follow-up prompt to add labels, security controls, or a second level of detail instead of overloading the first prompt.
Good fit for technical docs
AIDrawIO is built around engineer-first diagram workflows. Generate the first version fast, keep the XML editable, and link the output into docs, reviews, runbooks, or design discussions.

AI Diagram Generator
AIDrawIO turns plain-English prompts into technical diagrams you can keep editing. Describe the system, process, or workflow you want, then export draw.io XML or share the result as SVG or PNG.
AI Technical Diagram Generator
AIDrawIO focuses on technical diagrams engineers actually need: architecture diagrams, UML, ERDs, sequence diagrams, infrastructure maps, and cloud designs. Prompt first, then keep refining the result as an editable diagram.
AIDrawIO vs Eraser
Choose AIDrawIO if you want prompt-first diagram generation with draw.io-compatible output and export flexibility. Choose Eraser if your team prefers an opinionated docs-plus-diagram workflow inside its own environment.
Want this for your team?
AIDrawIO Pro gives your whole team unlimited diagram generation, shared workspaces, version history, and access to GPT-5 and Claude.

Frequently asked questions
What should I include in an architecture diagram prompt?
Name the main clients, services, data stores, integrations, and any boundaries such as VPCs, internal networks, or domains. That gives the model enough structure to place components clearly.
Can I use this for cloud and software architecture?
Yes. This page works for software architecture diagrams, cloud architecture overviews, and technical system diagrams that need editable output.
Is this tool really free?
Yes. You get 5 free generations per hour with no account required. Sign up for unlimited access with GPT-5, Claude, and Gemini Pro.
What diagram formats can I export?
The generated diagram is draw.io XML. Copy it and import it into draw.io or diagrams.net. Sign up to also export as SVG or PNG directly.
Which AI models are used?
The free tier uses Gemini Flash. Subscribers get access to GPT-5, Claude Sonnet, Gemini Pro, and more — with better layout quality.
Can I edit the generated diagram?
Copy the XML and open it in draw.io, or click "Save & Edit Diagram" to open it in AIDrawIO where you can visually edit, restyle, and re-prompt.
How do I get started?
Describe your diagram in the box above, then click Generate (or press ⌘↵). The placeholder text shows you the kind of detail that works best.
Will my prompts be used to train AI?
No. Prompts are sent directly to the AI provider and are not stored or used to train models by AIDrawIO.
