Meet JIMI, the schedule assistant that actually understands you. No more fiddling with forms. Just type "Dentist appointment tomorrow at 2pm" and JIMI takes care of the rest: it reads your message, extracts the right details, and — once you confirm — adds the event straight to your own calendar. If something's missing, it asks you kindly — it never guesses, and never writes anything without your go-ahead. Connects to your real calendar JIMI works with the calendar you already use — nothing to migrate, no separate agenda to maintain: • Google Calendar • Outlook / Microsoft 365 • Apple iCloud and other CalDAV calendars Every event JIMI creates lands directly in your calendar, and you can open it there in a single tap. What JIMI can do • Create an event from a single sentence • Edit or cancel an existing appointment • Tell you what's coming up today, tomorrow, or next week • Handle fuzzy dates: "tomorrow", "Friday", "in two weeks" • Keep your timezone right, wherever you are • Tell personal and professional events apart You're always in control JIMI shows you what it understood and waits for your confirmation before adding, editing or cancelling anything. Connect a calendar in one tap from the home screen — and disconnect just as easily from the About page whenever you like. A real conversation JIMI speaks your language. It asks for clarification when needed and keeps track of the dialogue, so you never have to repeat yourself. Built for everyday life A clean, focused interface designed for the moments when you don't have time to dig through menus. JIMI is a passion-driven project. Your feedback is welcome — it helps it grow!
