One year of parties. One companion who remembers the details.

Keep Osti, GreyDoor’s AI party-planning companion, for a full year. Plan holidays, birthdays, dinners, showers, backyard gatherings, murder mysteries, and the parties you have not thought of yet.

Osti can help with:

• Plans built backward from each party date

• Checklists, timelines, reminders, and assignments

• Invitations, RSVPs, and guest-message drafts

• Budgets, shopping lists, and purchase tracking

• Food, drinks, quantities, and kitchen capacity

• Colors, decorations, music, layout, and atmosphere

• Weather, parking, neighbors, children, pets, and accessibility

• Party-day guidance, host preparation, and cleanup

• Shareable photos and reusable notes from past parties

Your annual membership includes Osti assistance for up to three active parties at one time. You may save additional parties without activating Osti. Completing or canceling an active party releases its Osti slot.

This membership is $190 per year and renews annually until canceled. Cancellation takes effect at the end of the current paid year.

Osti uses AI to create personalized suggestions and help organize your parties. Responses may occasionally be incomplete or inaccurate, so review important details before acting. Osti will ask for confirmation before sending communications or making consequential changes.

Themed and licensed experiences are purchased separately unless a product expressly states that one is included.
