sysdraw

Purpose: Sysdraw is a browser-based editor for system design and architecture diagrams, with an infinite canvas.
AI diagramming: Users can describe a system in plain English and receive an editable diagram that they can refine in chat or by prompting changes to a canvas selection.
Diagram modes: The site lists flowchart, sequence, class, ER, and state diagrams, plus a BPMN 2.0 palette.
System design tools: The editor includes a searchable icon library for services, queues, databases, caches, and gateways, along with connectors that snap to anchors and route around obstacles.
Mermaid: Sysdraw imports Mermaid diagrams in eight listed types: flowchart, sequence, class, state, ER, gantt, pie, and gitGraph.
Collaboration: The canvas supports live cursors, selections, comment threads, @mentions, and email invitations with view, comment, or edit roles.
Sharing and embeds: Users can publish view-only links and embed live diagrams in Notion, blogs, or READMEs using an iframe.
Exports: The site lists PNG, SVG, PDF, and JSON exports, with plan availability varying by tier.
Offline and accounts: Local-first auto-save works offline without signup; signing in enables cross-device sync.
Integrations: The site specifically describes embedding diagrams in Notion, blogs, and READMEs, and importing Mermaid diagrams on Pro.
Data ownership: The terms state that users retain ownership of the diagrams and other content they create or upload.
Security and availability: The terms say the service is provided as is, without an uptime or error-free guarantee, and advise users to back up important work by exporting it.
Billing and refunds: The terms state that Paddle processes payments and that new subscriptions and upgrades have a 14-day money-back guarantee.
Audience: The homepage describes Sysdraw as built for engineers who draw systems and everyday system designers.
Price from: $6/mo
