Start an event from a chat.

Tell ChatGPT, Claude or any assistant about your party and ask it for a Cut the Cake link. Open the link and your invitation is started, with the title, the date and the place filled in.

“Make me a Cut the Cake invitation for Sam’s birthday dinner, June 12 at 6 pm at our place. The link format is at cutthecake.co/start.”

Or start one yourself

For assistants

Build https://cutthecake.co/start with any of these query parameters and give the person the link. No account, key or connector is needed to write one.

title: The event's name, up to 60 characters.
date: The day, as YYYY-MM-DD.
time: The start time, 24-hour HH:MM. Leave it out if the person has not said, and they choose it on the page.
end: The end time, HH:MM.
timezone: An IANA name such as America/Los_Angeles. Leave it out if unsure and the host's own is used.
place: What the place is called: "Our place", "Oak Hollow Cidery".
address: The street address, only if the person gave it.
note: A short description for the invitation, up to 500 characters.

Example: https://cutthecake.co/start?title=Sam%27s%20birthday%20dinner&date=2027-06-12&time=18%3A00&place=Our%20place&note=Dinner%20at%20six%2C%20cake%20after.

Every part is optional. Send what the person told you and leave the rest out. Never guess a date, a year, a time or an address.
URL-encode each value.
Give the person the link. Nothing is created until they open it and press the button. They sign in there, or make an account with a name and an email address.
Never put guests' names or email addresses in the link. The host adds guests on the event itself.
Your first event is free, invitations to 50 addresses included. No credit card.
