Hi Product Hunt, I'm Mounir, the maker of ExcaliClaw. I love hand-drawn diagrams, but they kept getting lost in random files, and my AI agent could only give me Mermaid text or ASCII boxes. So I built a workspace where diagrams live, stay organized, and your agent can draw in them. What you get: • Collections and instant search, so nothing gets lost • Real-time collaboration, sharing by link or by name • An MCP server: connect Claude, Cursor or VS Code (OAuth, nothing to paste) and let them create and edit diagrams • Version history, trash and backup export, so mistakes are cheap • English, Español and Français Pricing, plainly (excl. VAT): • Free: 200 drawings, unlimited AI (MCP) use, no credit card • Starter: €9/month (unlimited drawings, 30-day history) • Pro: €29/month (embed in your site, unlimited history; extra teammates €3/month) It uses the Excalidraw editor for drawing and is an independent product. I'd love to hear how you document architecture today, and what would make an AI-drawn diagram trustworthy enough for you to keep. Thanks for taking a look!
