Birthday card FAQs
Everything about sending one
How do group birthday cards work?
Start a card, share one link, and everyone adds their note from their own phone or laptop. No one sees the card until you decide it's full and send it. It arrives as a single, beautifully laid-out card on the big day.
Can everyone sign the same birthday card online?
Yes. There's no limit on signers. Each person places their message anywhere on the page, picks an ink colour, and can add a photo or GIF. The card stays completely private until you send it.
Is CardShareAI free?
Yes, you can design a card, collect signatures, and send it for free. Paid plans add team features, scheduled sends, and a saved archive of every card you've organised.
How do I send a birthday card by email or text?
When the card's ready, enter the recipient's email address or copy a shareable link to drop into a text. They open it right in the browser. Nothing to download or install.
Can I schedule the card to arrive on their birthday?
Yes. Pick the date and time and CardShareAI delivers it then, so the card lands right on the morning of the birthday, even if you set it up weeks ahead.
Can I add photos, GIFs, or a group message?
Every signer can add a photo or GIF alongside their note, and the AI can draft a shared opening message that sets the tone for the whole card.
Whose birthday is coming up?
Set up the card in two minutes, share the link, and let everyone sign. We'll handle the cover, the layout, and the reminder
