Magical Birthday Planner

Building Magical Birthday Planner - AI-powered tools to plan unforgettable kids’ birthday parties. Sharing the journey & learning in public. #BuildInPublic 🎉✨

Nobody plans a kid's birthday at a desk. It happens in a parking lot, a waiting room, on the couch at 10 pm.

So v1.0 is a phone app first. It installs from the browser like an app, and on a laptop you get the same single column.

The part of a launch nobody sees:

Jul 31, 2025 — first commit
Aug 2025 — 435 commits on a prototype
Oct 6, 2025 — last prototype commit
Then nearly a year of nothing.
Oct 2026 — the rebuild
Oct 13, 2026 — launch

It launches October 13. This week I'm posting how it got built — mistakes included.

Follow along if that's your kind of thing.

Why I built Magical Birthday Planner — the short version, before it launches on October 13, my daughter's 7th birthday. 🧵

AI helps where ideas and judgment help: themes, activities, plans, what to say.

Plain software handles what has to be exact: accounts, RSVPs, totals, payments.

The idea behind Magical Birthday Planner in one line:

A birthday party is one project, so it should be one plan.

Venue, theme, activities, guests, invitations, RSVPs, food, budget, checklist — all reading from the same party.

Parents: what holds your plan together today?

[Magical Birthday Planner @MagicalBPlanner]

The first requirement for this product didn't come from a spec. It came from my daughter's birthday.

The hard part of planning it wasn't any one task. It was that none of the pieces knew about each other.

So I built one where they do. It launches October 13 — her 7th birthday.

[Magical Birthday Planner @MagicalBPlanner]

Planning a kid's birthday is a distributed system with no database.

Ideas in search results. Guests in message threads. The budget in a note. Dates in a calendar. Every piece updated by hand, and nothing keeps them in sync.

That's the bug I set out to fix.
