Release Notes
Language Localization in the Web App
Harvey now supports language localization for the web app, letting you set both the interface and Harvey's responses to your preferred language.
What’s New
Harvey now supports language localization for the web app, so you can set Harvey’s interface and responses to the language you’re most comfortable working in. With this update, you can:
- Select an Interface language to change the language of menus, navigation, and system messages throughout Harvey's web interface
- Select an Output language to control the default language Harvey uses when generating responses

Note: At the time of GA, interface language localization will be available in French (Canada) and French (France) only. Additional languages will be introduced on an ongoing basis.
Why It Matters
Language localization allows you to navigate Harvey’s web app and responses in your preferred language, helping you to work smoothly and efficiently.

FAQs
Q: Can I ask Harvey to respond in a language other than my Output language?
Yes. You can ask Harvey to respond in a different language at any time. Simply specify the language in your prompt, and Harvey will use it for that response, overriding your default Output language.
For example, if your Output language is set to French but you write in English or request an English reply, Harvey will respond in English.
Q: Will more languages be available?
Yes. Harvey plans to add more languages throughout 2026.
