Language
?
Generate filler in another language. Arabic auto-flips to right-to-left. Asian languages use character-aware replacement that respects script structure.
Options
Language Style
?
Authentic uses real words from the language. Phonetic invents text that looks and sounds like the language but isn't real.
Proper Nouns
?
Preserve Shape keeps names the same letter count so layout columns stay pixel-perfect.
Tone (Semantic only)
?
