The Party Operating System
Partyyy is the software behind the parties people talk about for the rest of the year. Guest lists that remember everyone across every party you've ever thrown. RSVPs that actually come back. Badges, karma and votes that turn a guest list into a community — and a live wall in the corner of the room that makes it all visible at 2am.
The thing nobody tells you
Forty people. Six who never reply. Four who reply "maybe" and mean no. Two vegans, one nut allergy, someone who needs a lift from the station, and a spreadsheet that died in 2023. Then next year you start again from nothing.
Names, numbers, who's with whom, who came last time, who said yes and vanished. Partyyy keeps one guest book across every party you've ever thrown, so party number nine starts from party number eight rather than from a blank page.
Invitations by email and WhatsApp, a chase list ranked by who's been quiet longest, one-tap nudges, and a record of exactly what each person was sent and when — so nobody gets asked twice and nobody gets missed.
Most party tools stop at the door. This one keeps going: badges awarded, karma banked, votes counted, photos filed, and a Party Journey each guest can scroll through before the next invitation lands.
Two rooms, one system
Every guest gets a personal, password-free page for the party. You get the room behind it — every number live, every guest one click away.
What's in the box
Start with the guest list and invitations. Turn the rest on when you want it — every game, every channel and every theme is a switch per event.
One record per human, reused for every party. Partners linked so couples list together. Admin tags, notes, avatars pulled from six sources, CSV import, and filters for every slice you actually chase.
Personal magic links — no accounts, no passwords. Configurable form: drinks, dietary needs, nights staying, travel, plus five custom questions of your own and an anonymous confession box. And a date poll for the party that exists before its date does.
Per-event templates for all three. WhatsApp invitations go out on our Business number or yours, texts carry a meter that says what they'll cost, and a once-only post-RSVP welcome fires by itself.
Award badges for the things people actually do. Karma accrues across every party you've thrown, scores a leaderboard, and unlocks a trophy cabinet each guest can show off.
Award categories with cheer messages, and live polls for the decisions you'd rather crowd-source — what time dinner is, which stage gets the big rig.
If people are staying over, list what you've got to sleep them in and place them night by night. Guests ask for a bed from their own dashboard; the arithmetic that goes wrong at 1am is done for you.
Lay out the sittings and the head count comes off the guest list itself — who's eating, what they can't eat, and whether there's enough of it. Then lay out the room and the seating plan proposes itself, keeping apart the two people who mustn't be sat together.
The clay shooting, the boat trip, the sauna hour, the club night. Each holds a set number of places and a price a head; guests put their own names down, a full one starts a waiting list rather than turning anybody away, and the desk knows who has paid and who owes.
For the party people ask to join: a public page in your own theme, a review queue, and one button that turns a signup into a guest. Or one link you paste into the group chat, and whoever opens it is on the list. We're not a ticketing platform — sell wherever you already do, upload the list, run it here.
A three-column live display for the corner of the room: vote results, karma standings, rotating portraits and guest answers. And a comment wall on the party page itself, where guests write to each other instead of to you.
One tap turns the entire guest experience into a prohibition bar, a festival field, a Venetian masked ball or a black-tie spy thriller. You pick which worlds your party offers — and every one of them has its own name for the party AI, from The Barman to Q Branch.
A planner that sets the party up by asking you about it, then dresses it. A chat bubble in your console that just does what you tell it. The same bubble on every guest page, answering their questions and acting on the answers — RSVP, vote, book, ask for a bed. Plus in-character chats, portrait renders and drafted chase messages.
Your own address on any of seven domains, an open REST API, and a hundred and thirty-five MCP tools — so Claude on your phone, ChatGPT, Claude Code or Cursor can run your party directly, with nothing to install.
Event phases
A party isn't one thing. The weeks before, the night itself and the week after are three different jobs — so the guest page becomes three different pages, on its own, without you touching a setting.
Big clock, ticket stub, who's coming so far, RSVP nudges, and info pages that unlock on a schedule you set. Anticipation is a feature.
The DJ line-up and running order surface as full-width blocks, and a one-tap voting panel appears. Party day runs past midnight until 6am, because 1am is exactly when someone checks the line-up.
The countdown becomes a days-ago card, results open up, photos land in the album and the badges get handed out. Three zeros under "until doors open" helps nobody.
The long game
The features that matter most are the ones that span parties. Karma earned at last summer's barn party is still on the board this Halloween. The badge someone won for feeding thirty people is on their profile forever.
The party planner
Name a party and the planner takes over: what kind of party, where, when, how guests get in, who's staying over, whether there's food. One question at a time, most of them answered with a tap. Out the other side come the fonts, the colours, the ticket, every word on the dashboard, your invitation, your WhatsApp copy and the personality your party AI answers in — composed together, so they look like one party rather than eleven settings pages.
Party AI
A bubble in the corner of every guest page, answering in your party's own voice from your party's own data — when, where, who's coming, what to bring, what they're down to help with, and what they RSVP'd. No WhatsApp number, no assistant to set up, no plug-in.
Themes
Thirteen complete alternate skins for the entire guest experience — not a colour swap, a different world. Every page a guest can visit gets rewritten in that voice, with its own soundtrack and its own name for the party AI — you ask The Barman in the speakeasy and Q Branch in the spy thriller. You choose which ones each party offers.
Art-deco brass on candlelit coal, a peephole in an unmarked door, and a barman who answers your questions.
A tiny festival in a field at dusk. Lineup-poster type, bunting, and your party billed as the headliner.
Gold filigree on midnight, a dance card instead of an RSVP, and guests who reply by footman.
A New Year's Eve ballroom at one minute to twelve. Confetti in the rafters and a great clock with its hands a minute short.
And nine more, whatever your party actually is:
All thirteen are included on every plan, every party, no unlock. If none of them is your party, we'll build you one for £15.
Who it's for
Turn on the guest list, the RSVP form and one email template. Ignore everything else. You'll still get dietary requirements collected properly and a page you can send instead of typing the address out fourteen times.
The sweet spot. Guests log the flights, hotels and lifts they're taking and find out who else lands within the hour; beds, bunks and tents allocated night by night; jobs claimed off a board; polls for the dinner time; the TV wall on Saturday night; badges and karma on Sunday.
Multi-day schedules and stage line-ups that unlock on the day. A Backstage desk for the acts, the caterers and the crews, with every duty cued to the run sheet. Capacity tracking against a venue limit. Attendance check-off at the gate on a phone. Its own domain, its own theme, its own everything.
