Frequently asked questions
Do I need a Claude API key?+
No. ArchAssist includes generation by default — your free quota uses our backend. Power users can paste their own key in Advanced settings to bypass the daily limit.
What architecture types are supported?+
Five domains: Data & Analytics, AI & Agentic, Cloud Infrastructure, Application/Technical and Network. The model auto-detects the type from your description, or you can pick it manually.
Can I export my diagrams?+
PNG export is available on every plan. Pro adds PDF export of the full risk report and Mermaid source download.
Is my data stored?+
On Free, nothing is persisted — generations happen in real time and are not saved. Pro plans get diagram history so you can revisit and re-export past results.
