Change the site language
How the language switcher works, and how that differs from generate language.
Use the language control in the header. English is at porosheets.com. Other languages use a prefix, such as /es or /ar.
The site language changes chrome and marketing copy. It does not change worksheet output. Pick a language on Generate if you want the sheet in another language.
You can type class and lesson titles in any language regardless of the site setting.
