Design Your Own Invitation With the AI Builder
Our Sweet Day Team, October 28, 2026
Our Sweet Day has hundreds of invitation templates, but sometimes the one you picture is not among them: your daughter's favourite castle, a gift box in exactly her colours, the beach where you met. The AI Builder makes that invitation for you, from a description.
What the AI Builder Does
You describe the invitation in your own words, or attach a picture of your motif, and the AI Builder designs it from scratch:
- It plans the look: an idea, a palette and a type pairing that fit your theme, shown to you as a card within a minute or two
- It makes the artwork: painted scenes, objects and textures for your theme, not clip art
- It builds a working invitation: animated, interactive and made for phones first, with RSVP, the details, the photos and a "what to wear" section to play with
- It checks and polishes: it looks at its own work on a phone screen and a computer screen and fixes what it sees, version after version
You watch it happen: the progress shows each stage, from studying your idea to polishing the finished design, and the preview updates with every new version. You can leave the page; it keeps going, and it can tell you when it is ready.
Step 1: Open the AI Builder
Sign in (or create a free account) and choose AI Builder in the menu. Press New design, pick the occasion (a wedding, a birthday, a christening or a proposal) and the kind, such as a kids' party or a debut.
Step 2: Describe It
Write what you have in mind the way you would tell a friend. A theme, a feeling, colours, characters, a place. Some examples:
- "Disneyland theme, the castle and the main characters"
- "A simple, cute birthday RSVP: a pink gift box with a big white bow"
- "Kyoto in spring: paper lanterns, cherry blossom and ink wash"
You can paste or upload pictures too: a colour swatch, the cake, the venue, a character.
Step 3: Change Anything by Asking
The first version usually appears within a few minutes; the builder keeps refining after that. Then it is a conversation: "make the title bigger", "use the pink from my picture", "add fireworks over the castle". You can also tap any part of the preview to point at it, and say what to change there. Like any AI it will sometimes get things wrong; you can correct and revise everything.
Step 4: Use It on Your Event
When you like it, press Use this design. Create a new event with it in one step, or put it on an event you already have. From there it works like every other invitation: your words and photos in the live editor, a personal link for every guest, RSVPs and seating.
What It Costs
Making a design, trying it, and putting it on your event to fill in your names, photos and music are all free, so you can see and feel the whole invitation first. It is paid when the event goes out, whatever its guest count, even for a small party: $25.00 for a wedding, christening or birthday, $9.99 for a proposal, with no guest limit after that. On an event you have already paid for, it costs nothing more.
Fair Use
Every host can start one new design a day and send up to 20 messages a day to shape it, as many refinements as those allow. The whole site has a set number of design slots each day, first come, first served; the AI Builder page shows how many are left, and new slots open at midnight, Singapore time.
From the Gallery
Some designs made in the AI Builder join the public template gallery, chosen by our team, such as Magic Kingdom Day, a day at the park where the castle glows at the gate, and Tied With a Bow, a soft pink gift box whose lid lifts to show the birthday child's name. Anyone can use those like any other template.
