Yes! While the app's menus are in English, the AI itself is multilingual. How well it works depends on the specific AI model you choose, but top models like GPT-4o, Claude 3.7, and Gemini are excellent in dozens of languages. You can write your notes, documents, and prompts in French, Spanish, German, Japanese, etc., and the AI will generally understand and respond appropriately. It's great for translation too!
