Chega Aí
A digital party invitation in the voice of whoever is throwing it: guests listen, RSVP and get through the door with a QR code.
- In development: it runs end to end on my machine, with no launch date yet
- A 7 step editor with live preview, in-browser audio recording and real-time RSVPs
- Payments through Mercado Pago, in simulated mode for now; only the sandbox run is left
- 67 unit and RLS tests and 24 end to end tests, on desktop and mobile
How it worked before.
Party invitations today are a graphic sent on WhatsApp: pretty, but silent. Nobody RSVPs properly, the host spends the week chasing answers in private messages, and at the venue door the list is a sheet of paper someone crosses off by hand.
Chega Aí starts where the paper invitation never went: the voice. The host records the messages, the guest listens, and from there the invitation takes care of the rest of the party, from the RSVP to the door.
What changed.
The host builds the invitation in 7 steps with the preview alongside, records each audio clip on the phone (up to a minute) and can send grandma a link to record one too, no sign up needed. The guest opens the link, listens, answers the questions and RSVPs with their plus ones; the host dashboard updates instantly, without reloading.
After the RSVP, the invitation becomes the party: an entry QR checked in by camera or by the staff PIN, a moderated guestbook, a gift list with Pix and card contributions, and print-ready artwork. Party venues have their own plan and publish their clients’ invitations under their own brand, on their own address.
Every table has tested RLS, public forms are rate limited and IP addresses are stored only as a hash. It is still in development: payments run in simulated mode until I have Mercado Pago test credentials, and recording still needs testing in Safari on the iPhone.
A look inside.
The three steps, each showing what actually happens: the themes side by side, the microphone recording and the WhatsApp chat with the invitation link. 
From “I’ll be there” to “come on in”: the RSVP with guest counts, the gift list with a contribution filling up, the guestbook, the door check-in and the print-ready artwork. 
Pay once, no subscription. The free plan stays live for 24 hours, and when the host unlocks the full one, the link stays the same. Prices come from a single configuration file. 
For party venues and planners: the invitation carries the venue’s brand, on its own address, with a flat monthly fee and a charge per published invitation. 
The questions that come up most, answered before anyone asks: guests do not download an app or create an account, and the invitation does not show up on Google. 
The closing call to action, with the brand’s balloons. The logo is a pair of balloons that are also quotation marks: the party and the voice in one drawing.
