When to use this tool

Use it for network topology diagrams that need routers, switches, firewalls, VLANs, and sites mapped clearly.

Use it for operations runbooks, security reviews, and office or cloud network documentation.

Use it when traffic paths and network boundaries matter more than application-level detail.

Example prompts

Prompt 1

Corporate network with HQ, two branch offices over VPN, a DMZ hosting web servers, and a firewall.

Prompt 2

Enterprise network with HQ, two branch offices over site-to-site VPN, MPLS backup, DMZ web tier, and internal application network.

Prompt 3

AWS network topology with transit gateway, shared services VPC, private application subnets, inspection VPC, and on-prem link.

Prompt 4

Zero-trust network with identity provider, policy engine, segmented internal services, and mTLS between service groups.

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.

Frequently asked questions

Can I use this for network topology and security diagrams?

Yes. It works for LAN, WAN, VPN, subnet, firewall, and security-oriented network diagrams where boundaries and connectivity are the main story.

What makes a network diagram prompt clear?

Name the sites or zones, network devices, security controls, and the major paths between them. Mentioning VLANs, VPNs, or DMZs helps a lot.

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.
