Sathi is a connected ecosystem for home, work and everyday life. Conversations, files, mail, calendars and devices work with the context you allow, so you can ask about a document, draft a reply or set a reminder without moving the same information between apps. One Sathi per person, with family context shared by choice, in Nepali, English, Japanese, Hindi and Bengali.* In beta, used daily by its first families, with no billing today.
