Question 1

How does the AI processing work?

Accepted Answer

Describe your system in plain words — or paste a design doc, requirements, or technical notes — and DiagramThis uses AI to draw the architecture diagram, flowchart, or swimlane a principal architect would. The diagram stays fully editable: drag, rename, connect, and refine without losing the generated baseline.

Question 2

What happens to my data?

Accepted Answer

We do not use your content to train AI models. You can delete your diagrams and their inputs from your account at any time.

Question 3

What can I paste or upload?

Accepted Answer

Anything that describes a system or process: plain text (.txt), PDF, DOCX, Markdown, CSV, JSON — or copy-pasted content from any source: design docs, requirements, Slack threads, rough notes, even meeting transcripts (VTT/SRT supported).

Question 4

Can I use it without a subscription?

Accepted Answer

Yes — the free plan gives you starter credits with no credit card required, so you can try DiagramThis before paying anything. Pro adds a monthly credit pool, and you can buy top-up credits which never expire and have no monthly commitment.

Question 5

What is a credit?

Accepted Answer

Credits are how you spend AI generation. Each diagram uses credits based on the size and depth of its input — a short description costs less, a long or complex document more — so you only ever pay for what a diagram actually needs. Monthly credits refresh each cycle; top-up credits never expire.

Question 6

What diagram types are supported?

Accepted Answer

DiagramThis generates architecture diagrams showing systems and their integrations, multi-actor swimlane process flows, and current-state vs. to-be-state comparisons. Diagrams export to draw.io (fully editable), PNG, and a shareable HTML file.

Question 7

Do unused credits roll over?

Accepted Answer

Monthly subscription credits reset each billing cycle and do not roll over. Purchased top-up credits never expire.

Question 8

Is there a team plan?

Accepted Answer

Team features are on the roadmap. Currently each account is individual. The Pro plan (Monthly or Yearly) is well-suited for power users who create diagrams frequently, with top-up credits available whenever you need more.
