/ Core modules

Every part of the party, in one place.

Six modules that talk to each other — change a guest count and your menu, budget, and shopping cart update in lockstep.

Guest coordination

Import contacts, send digital invites, track RSVPs and plus-ones. Dietary preferences flow straight into your menu.

Menu & shopping

Build menus from a recipe library or your own. One click sends the auto-quantified list to Instacart, Walmart, or Amazon Fresh.

Live budget tracking

Set a total, watch categories auto-allocate. Variance alerts and savings suggestions before you overspend, not after.

Smart timeline

An AI-generated planning timeline with dependency-aware tasks, reminders, and a day-of running order on your phone.

Venue & logistics

Capacity validation, parking, weather risk flags for outdoor events, and shareable directions for guests.

Co-planners & sharing

Invite partners, family, or vendors with role-based permissions. Public event pages, private working space.

/ Creativity

Your party. Your aesthetic.

Design beautiful menus and invitation pages that match your event's vibe — no design skills required.

Menus that look as good as they taste

Choose a style, add your dishes, and let PartyOS handle dietary labeling, portion scaling, and one-click ordering. Guests see a beautiful menu page; you see a filled shopping cart.

  • Dietary filters auto-populated from guest RSVPs
  • Recipe library with 1,200+ dishes to draw from
  • Scales quantities instantly as headcount changes

Invitation pages guests actually want to open

Generate a shareable event page with a single link. Pick a color theme, add your details, and your guests get a beautiful RSVP experience — dietary preferences and all.

  • Themed pages that match your event's mood
  • Mobile-first, shareable via link, text, or QR code
  • RSVP data flows directly into your guest list
/ Intelligence

Seating that reads the room.

PartyOS learns your guests' relationships, personalities, and preferences, then suggests a floor plan that maximizes mingling and minimizes the awkward. Drag-and-drop any table — the rest re-balances in real time.

  • Family clusters stay together, friend groups merge naturally
  • Introvert / extrovert balance for conversation flow
  • Conflict-avoidance for known tensions, VIP positioning for honorees
  • Accessibility-aware placement near exits and amenities

/ Workflow

From "we should do something" to RSVP'd in minutes.

A three-step setup that scales from a Tuesday dinner to a 200-guest wedding.

STEP 01

Describe the vibe

Name your event, pick a date, set a rough budget. PartyOS proposes a planning template you can edit or accept.

STEP 02

Invite the people

Add guests by contact, email, or paste a list. RSVPs, dietary info, and plus-ones collect themselves.

STEP 03

Let the OS run

Menus auto-quantify, shopping carts pre-fill, the timeline schedules itself. You approve. We handle the rest.

/ Pricing

Free for your first party. Scales when you scale.

Choose the plan that matches how often you host. No hidden fees, no per-guest charges.

/ Questions

The short answers.

Is there really a free plan?

Yes β€” Confetti is free forever. Two active events, fifty guests each, full budgeting and RSVP tracking. We only charge when you want AI, shopping integrations, or to host bigger gatherings.

How does the AI seating engine work?

You tag relationships (family, friend, colleague), optionally add notes like "introvert" or "avoid seating with Dan", and the engine generates a layout that maximizes mingling and avoids conflicts. Every suggestion is editable β€” drag and drop overrides any optimization.

Which retailers can I order from?

Instacart, Walmart, Amazon Fresh, Etsy, and Drizly are live today. Whole Foods and Total Wine are rolling out this quarter. You can also export shopping lists as plain text or CSV.

Can my co-host see and edit the plan?

Co-planners get real-time access on the Host and Production plans. Choose between editor, contributor, or view-only roles. Changes sync instantly across devices.

What about privacy? Some of this is sensitive.

Dietary info, health notes, and guest relationships are encrypted end-to-end. We never share guest data with third parties, and you can delete an event β€” and everything in it β€” in one click.

Can I cancel anytime?

Yes. Cancel from your account settings and your plan stays active until the end of the billing period. Your events stay on the free tier afterwards β€” nothing gets deleted.
