Some birthday parties are just cake. The milestone zeros are productions.
A rented ballroom, three dietary factions, a slideshow of embarrassing photos, and a toast lineup nobody wrote down — until now. This plankit runs the whole night: the guest list with meals on every card, seats for everyone, the budget, a run-of-show timed to the minute, and a party page that answers every "wait, what time?"
The tribute slideshow: twelve minutes, cued on the run-of-show
Ten of ten seated, zero table-map arguments
The ballroom deposit — half paid, half tracked, nothing surprising
The ones with a zero at the end deserve a real plan.
A random Tuesday birthday needs a cake. A 50th needs a venue, a bar tab, ninety minutes that actually flow, and a slideshow that starts on cue. The plan holds all of it — and the screenshots below are the proof, not a promise.
The toasts & the moment
Who speaks, in what order, for how long — and when the slideshow rolls. The music board sits beside it: must-play, do-not-play, and the songs with a moment attached — the entrance, the cake, the last one of the night. Type with autocomplete or paste a list straight out of Spotify; it prints on the DJ's sheet. On the party below it's already done: Amy's two minutes, Dave's emcee glue, the twelve-minute tribute pinned to 8:42 on Dave's cue.
The slideshow, taken seriously
The plan carries it like a headliner: a collection task that starts months out, a pinned cue on the run-of-show — and Photo Drop on the party page, where guests post the embarrassing photos themselves, every one held for your approval.
Shaped to its number
Tell it it's a birthday and the night arrives shaped — cocktails, dinner, toasts, cake & the wish — then bend it to a 1st with grandparents or a 75th with a head table. Every part takes its own RSVPs.
Surprise mode
Flip "It's a surprise" and mark who's kept in the dark: they never get a personal link, an invite email, or a text — the app enforces it on every send, so one wrong tap can't ruin it. Cover-story invitations are next. COVER-STORY INVITES — COMING SOON

What party-throwers ask.
How airtight is surprise mode, really?
Surprise mode is on the plan today: flip it on, mark who is kept in the dark, and they never get a personal link, an invite email, or a text — the app enforces it on every send. Cover-story invitations are coming next. The one thing software cannot stop is your uncle telling him at golf. We give the uncle fewer chances.
Is this overkill for a kid's party?
For a random Tuesday 7th, probably — use the group text with our blessing. For a 1st with both sets of grandparents, a rented bounce house, and 30 adults? The plan earns its $59 by Thursday.
Can multiple people co-plan?
Yes — invite them with a scoped link, no password needed, so the two of you conspiring can both see everything, and the honoree sees nothing.
How does the photo slideshow work?
The plan carries it as a first-class item: a collection task that starts months out and a pinned cue on the run-of-show, exactly as the screenshots show. And Photo Drop collects the raw material — guests post photos and memories right on the party page, every one held for your approval before it goes public.
What if plans change?
Move the date and every guest page updates automatically — the party page always shows the live details. 30-day money-back on the plankit regardless.
