Question 1

What is ArkT?

Accepted Answer

ArkT is a free, AI-powered architecture diagram tool that lets you create multi-level system diagrams with infinite drilling depth. It features GitHub integration, real-time collaboration, and AI-powered impact analysis-all running privately in your browser.

Question 2

Is ArkT really 100% free?

Accepted Answer

Yes! ArkT is completely free with no hidden fees, user limits, or feature restrictions. We believe great tools should be accessible to everyone. You can create unlimited diagrams, use all features, and collaborate without any costs - the only exception is for AI-powered features, which require you to use your own API key.

Question 3

Do I need to sign up or create an account?

Accepted Answer

No signup required! ArkT works entirely in your browser. Your diagrams are stored locally, giving you complete privacy and control. You can optionally connect GitHub for sync and collaboration features.

Question 4

How does multi-level drilling work?

Accepted Answer

Multi-level drilling lets you dive infinitely deep into any node. Click a node to explore its internal architecture, then drill into sub-components. Breadcrumb navigation helps you track your location and jump between levels instantly.

Question 5

What AI features are included?

Accepted Answer

ArkT includes AI-powered impact analysis that detects how changes ripple through your architecture. Ask questions like "What happens if I change this service?" to understand dependencies. You can bring your own OpenAI API key (BYOK) for AI features, which also enable automatic generation of diagram parts to visualize your system's structure and changes.

Question 6

How do I integrate with GitHub?

Accepted Answer

Connect your GitHub account in Settings → Integrations. You can browse repository files, link nodes to code, sync diagrams to repos, and collaborate with your team. All connections use OAuth for security.

Question 7

Where is my data stored?

Accepted Answer

Your diagrams are stored locally in your browser using IndexedDB. Nothing is sent to our servers unless you explicitly sync with GitHub. This local-first approach ensures privacy and works offline.

Question 8

Is my data private and secure?

Accepted Answer

Absolutely. ArkT runs entirely in your browser-we never see your diagrams. GitHub integration uses OAuth with minimal permissions. AI features use your own API key. You have complete control over your data.

Question 9

How is ArkT different from Lucidchart?

Accepted Answer

ArkT is 100% free with unlimited diagrams and features. We specialize in multi-level architecture diagrams with infinite drilling depth-something Lucidchart doesn't offer. We're built for developers with GitHub integration and AI impact analysis.

Question 10

What use cases is ArkT best for?

Accepted Answer

ArkT excels at: software architecture documentation, microservices mapping, system design interviews, API design, infrastructure planning, and technical decision records. Perfect for developers, architects, and technical teams.
