ArchitectureDiagram.ai

Product: ArchitectureDiagram.ai generates architecture diagrams from natural-language descriptions.
Diagram formats: It supports Mermaid flowcharts, draw.io diagrams, Excalidraw sketches, and AI-generated images.
Editing: Users can refine diagrams through chat-based editing.
Party Mode: For image output, Party Mode generates candidates from multiple models in parallel for comparison.
Templates: The product advertises 24 ready-to-use templates, including microservices, serverless, Kubernetes, and RAG pipeline blueprints.
Export and sharing: Diagrams can be downloaded as PNG, copied to the clipboard, shared by public read-only link, or embedded with an iframe.
Presentation Builder: The Present view creates .pptx and .pdf decks with speaker notes and is available on Hacker and above.
Expert Chat: Hacker and higher plans include Expert Chat for architecture feedback; Free and Builder users receive three review messages total across diagrams.
Integrations: Public diagram links and embeds are described for use in Notion, Confluence, GitHub READMEs, and other iframe-supporting wikis.
API: The API uses bearer keys and can generate Mermaid text synchronously or rendered PNG images asynchronously; the API page lists generation costs of $0.05 and $0.20 respectively.
Security and data: The privacy policy says data is stored with Supabase hosted on AWS, protected by row-level security, and encrypted in transit and at rest; prompts and generated outputs are retained to improve generation.
Payment handling: Payments are processed by Stripe, and the privacy policy says ArchitectureDiagram.ai does not see or store card details.
