Ohai – Powering Your Day, Every Day Ohai! I’m O, your personal assistant here to help your whole household run smoothly—from syncing schedules to managing everyday to-dos and reminders—so you can do less juggling and spend more time living. Here’s how I help you get it all done: - Master the School Year I keep your family’s calendar organized—from the first day of school to Maycember madness—so you never miss a thing. - New!

Just send it to me, and I’ll scan it for key dates and add them for you. No typing, no missed events. - Shareable Calendars = Less Work for Everyone Once you’ve scanned or synced a school calendar or sports schedule, you can share it with other parents via a simple link so they can add it to their calendars too. Be the hero of your group chat—scan it once, and everyone stays in sync. - Meal Plans for Hectic School Days I can suggest easy weeknight dinners and allergen-free school snacks, build your grocery list, and even send it to Instacart for you. - Delegate Tasks Like a Pro From drop-off and pickup to snack duty, I help you coordinate tasks and send reminders—so nothing slips through the cracks. - Make Time for You (Yes, You!) I block time for workouts, focus sessions, or even just a quiet coffee—because back-to-school doesn’t have to mean back to burnout. - Inbox to Calendar, Instantly Forward me those school newsletters, PTA updates, and “pls read!” emails. I’ll scan them for key info—like pajama day and permission slips—and add it all to your calendar and to-do list. -One Family Calendar From soccer games and science fairs to playdates and PTA meetings, I keep your whole family in sync with one smart, shareable calendar. - Just Say It Out Loud Now with voice and video, I let you brain dump while packing lunches or sitting in the pickup line.
