Osti: Three Months

Keep Osti nearby through the parties already waiting on your calendar.

Osti is GreyDoor’s AI party-planning companion. Osti creates and maintains your plans, remembers the details, and helps you know what to work on next—whether you are planning Halloween, Thanksgiving, Christmas, a birthday, or an ordinary gathering at home.

Osti can help with:

• Personalized checklists and timelines
• Invitations, RSVPs, and guest communications
• Budgets, purchases, and shopping lists
• Food, drinks, quantities, and serving plans
• Colors, decorations, music, and atmosphere
• Space, parking, weather, children, pets, and accessibility
• Party-day guidance and host preparation
• Shareable photos and notes for future parties

Your three-month plan includes unlimited planning with Osti 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 for another party.

This plan provides three full months of Osti access for $57. It does not renew automatically.

Osti uses AI and may occasionally provide incomplete or inaccurate information. Review important details before acting. Osti will ask for confirmation before sending communications or making consequential changes.
