An online birthday card they can actually play with
A birthday message gets read in two seconds. A KoiKoi birthday card gets played with. You add your photos, memories and a heartfelt letter; we turn them into a little interactive celebration they open from a single link — perfect for a midnight wish, a long-distance birthday, or when you can't be there in person.

Why an interactive birthday card beats a text
Everyone gets a flood of "HBD 🎉" messages. An interactive card stands out because it takes them somewhere: they tap, they play, they find your photos, and they reach a letter at the end. It feels like a gift, not a notification.
It also travels well. Whether they're in the next room or another city, the surprise arrives at exactly the moment you send it — schedule-free, shipping-free, and in time for 12 AM.
Who it's for
Girlfriends, boyfriends, husbands and wives get the most romantic version, but the same card works for a best friend, a sibling, Mom or Dad. You choose the words and photos, so the tone is yours: sweet, funny or emotional.
Birthday letter lines to borrow
- “Another year of you is the best thing that happened to this year.”
- “I made you something instead of just texting "happy birthday" — keep tapping.”
- “Every photo in here is a day I'm grateful I got to spend with you.”
- “Make a wish. If it involves me, I'm already saying yes.”
- “Wherever you are today, I hope this makes you smile like you're right here.”
Frequently asked questions
Can I make it tonight and send it at midnight?
Yes. It takes a few minutes to make, and your private link is ready as soon as you unlock it, so you can send it right at 12.
Can I add our photos?
Yes. Your photos are part of the card — they're revealed as the memories section.
Do they need to download an app?
No. It's a private webpage. They tap the link and it opens in their phone's browser — on WhatsApp, Instagram or anywhere else you share it.
Can I preview it before sending?
Yes. Preview Mode lets you walk through the full experience exactly as they'll see it before you unlock the private link.
How long does the link work?
The private link stays active forever — it never expires, so they can come back to it any time.
Is it a subscription?
No. It's a one-time payment per surprise — no subscription, no autopay.
