Czech diagrammer

Type an English or Czech sentence. English is translated into natural Czech; Czech gets checked. Every sentence is diagrammed by phrase type and case.

What you type is sent to Anthropic's Claude to make the diagram, so don't type personal information. The diagrams are made by AI and can contain mistakes. If something looks wrong, use "Flag a problem" and send your flags to Katy.
