Otto is your AI voice assistant for email and calendar. Talk to your inbox the way you'd talk to a person — archive, draft, send, schedule, and prioritize, all hands-free. WHAT YOU CAN DO Manage email by voice Ask Otto to read your latest message, draft a reply, send it, or archive it. No typing, no swiping, no thumb gymnastics. Find what actually matters Ask "What's my most important email?" and Otto surfaces the messages that need you — not the newsletters, receipts, and noise. Run your calendar without lifting a finger "Create an event for Thursday at 3 with Sarah." "What's on my calendar tomorrow?" "Move my 2pm to 4." Otto handles your Google Calendar the same way it handles your inbox. Set rules that work in the background Tell Otto "always archive promotional emails from Sephora" or "always archive emails that look like recruiter outreach," and Otto keeps your inbox clean even when the app is closed. PERFECT FOR - Walks, workouts, and time outside - Commutes on transit or as a passenger - Cooking, chores, and anything where your hands are busy - Inbox-zero people who want a faster way to triage PRIVACY AND CONTROL Otto connects to your Gmail and Google Calendar through Google's official sign-in.
