sysketch: your system, sketched sysketch: your system, sketched

Describe your system. Get the diagram.

Add sysketch to your AI assistant and ask for a system design diagram. The assistant writes a few lines describing your system, and sysketch draws a clean, hand-sketched diagram you can open, download or share. In Claude and ChatGPT it opens right in the chat.

Other assistants

Any app that supports remote MCP servers over Streamable HTTP can use the same URL. Coding assistants like Claude Code and Cursor can also run sysketch on your computer, which saves diagrams straight into your project and supports official logos: see the setup guide.

Product logos

Product names like stripe, kafka or postgres show the product's logo from Simple Icons, unaltered and only inside diagrams. Names and logos are trademarks of their owners; sysketch isn’t affiliated with or endorsed by them. Brand owners can ask for a logo to be removed by opening an issue.

Privacy

Nothing is stored. Each diagram link contains its own description, so anyone you share a link with can see that diagram. Don’t put secrets in diagrams.
