Pay once · No ads · Built for the kids throwing it

They have been married fifty years. You have three months to plan an anniversary party that does it justice.

The kids are throwing it — which means you, your siblings, three time zones, and a guest list that spans 1976 to now. This plankit is built for adult children planning their parents' big one: the vows again, the toast order, five decades on photo boards, and a party your parents just get to walk into.

"Best man, 1976 — flies in from Phoenix" — the surprise, on Walter's guest card
The vow renewal, pinned at 5:00 — it's a real toggle, not a metaphor
Sibling lanes on the task list — venue, food, and the one job Tomás will do
The 1976 cake, from the original bakery's recipe — a real budget line

The PlanFlow anniversary cockpit — 92-day countdown, 10 of 10 seated, the vow renewal and toasts queued, and the 1976-details note

Built for the big ones

The party is one night. The tribute is fifty years.

Every great anniversary party centers on the story — the 1976 wedding photo, the houses, the kids, the trip they still talk about. The Alvarez plan below carries all of it: the boards, the slideshow cue, the same-pose portrait at golden hour. Unretouched screenshots of a sample plan we built end to end to show you exactly what it does.

The decades tribute

The Decades is a real module: the milestones, year by year, kept in order and printed in the program. Boards and the pinned slideshow carry the room, and Photo Drop already collects guests' photos and memories on the party page — each held for your approval. The decade-sorted timeline they feed is next. DECADES TIMELINE — COMING SOON

Sibling mission control

One live plan instead of three time zones of good intentions — and the task list carries the lanes by name: Daniel owns venue, Marisol owns food, Tomás owns the slideshow. Each sibling gets a scoped link — their lane, nothing else.

Vow renewal — a real toggle

Flip it on in setup and the ceremony takes its place: the officiant, who stands with the couple, and the moment itself — pinned at 5:00 on the Alvarez run-of-show. Skip it and the plan stays a pure party.

Toasts & the golden hour

Who speaks and in what order — the kids, then the best man from 1976 — when the slideshow rolls, when their song plays again, and the same-pose portrait on the terrace. The ninety minutes that make everyone cry, scripted.

Don't take our word for it

One real golden anniversary, in pictures.

These are unretouched screenshots from the real product. Frank & Rosemary Alvarez's 50th is a sample plan we built end to end to show you exactly what it does — ten guests spanning five decades, one evening on the terrace at Willow Creek. Click any of them to look closer.

The heart of the night

Fifty years, five boards, one room in tears.

The Alvarez plan runs the tribute the way the screenshots show: boards by decade, memory cards at every seat, the slideshow pinned to a cue — and The Decades module holding the milestones, year by year, printed in the program. Photo Drop already collects guests' photos and memories on the party page. Sorting them into a decade-by-decade timeline and keepsake is coming soon. DECADES TIMELINE — COMING SOON

Questions

What the kids ask.

Three siblings, three states. Does this actually work shared?

It is the reason this plankit exists. Everyone works from the same live plan, and the lanes live on the task list by name — venue, food, the slideshow — exactly as the Alvarez screenshots show. Each sibling gets a scoped link — their lane, nothing else. The group chat goes back to being about the dog.

How does the guest memory collection work?

Two ways today: guests post photos and memories straight onto the party page — Photo Drop, every post held for your approval — and the tribute itself runs on the plan: The Decades milestones printed in the program, photo boards by decade, memory cards at every seat (a real budget line), and the slideshow pinned to a cue someone owns. Sorting the guest posts into a decade-by-decade timeline is coming soon.

Can we keep it a surprise from mom and dad?

The Alvarez plan keeps one: the best man flying in from Phoenix lives in a note and on a guest card the honorees never see. Full surprise mode — the honoree firewall the Birthday plankit has today, plus cover-story invites — is coming to Anniversary soon.

They want to renew their vows. Big deal to add?

One toggle — literally. Anniversary setup has a Vow Renewal switch: the officiant, who stands with the couple, and the moment itself slot into the run-of-show between arrival and dinner. Skip it and the plan stays a pure party.

Is $99 the whole cost?

For the planning, yes — one-time, sibling links included, 30-day money-back. The party itself is between you and the caterer.
