Greeting card
A message in a chat takes two seconds to write and two seconds to forget. A card is an envelope somebody opens — even when it arrives through that same chat.
No password — you sign in with a link by email, or with Google or Apple.
Birthday, Christmas, a wedding anniversary, a day of remembrance — everything after this follows from it: the suggested wording, the designs, the tone.
Type your own words, reuse one of your saved templates, or let the AI draft one: warm, funny, formal or quiet, short or long, with your keywords. What comes back is a draft you edit in the same box.
Five designs, from festive to plain. Add your own picture and pull it into place in the frame — most of the time that photo is the card.
At the end you get a link. You send it over WhatsApp, email or SMS; the app just opens your own window with the text ready. You press send, not Kalendo.
The link opens a closed envelope and one line: tap to open. Only then comes the card with your text, your photo and your name underneath.
Nothing to install, nowhere to sign up. That is the actual difference from most e-card services — and the reason people who have never heard of Kalendo still open the card.
One quiet line says the card was sent with Kalendo. Nothing else. The larger invitation block that used to sit there was deliberately removed: opening a card is a moment between two people.
Someone pasting the link into WhatsApp sees an envelope and “a card from …” — not the contents. What is inside stays inside, including from the servers that draw previews.
The card lives behind a random link, and whoever holds it can open it. That is the whole access rule, deliberately: requiring an account to receive a birthday wish is a hurdle in the wrong place.
What does not happen: the card shows up in no search engine — card addresses are closed to crawlers. And your text stays where it belongs, on servers in Frankfurt. The AI never sees it; it only gets what you hand it for a draft — your keywords, the first name, the relationship, the occasion, age and interests. No surname, no address.
Prefilled with the first name from your profile — first name only, because a signature under a birthday wish is not a full name. Without a sender the card reads “a card for you”, which is exactly what makes a link hard to place.
The first time a card is opened, that is recorded. Your overview shows how many of your cards were opened — you cannot tell for an individual card.
There is a separate, quiet design — black on white, no ornament — and the festive ones are not offered at all. The suggested wording changes too: two sentences that are not congratulations and that ask for no reply.
A card is no use if the day goes by. The first reminder arrives two weeks ahead, three more follow, and the last one lands on the morning of the day itself.
Not a print service. A physical card in a letterbox is not something this app can do right now — what it can do is the card that is on the recipient’s phone two minutes from now.
And not an animation stage. No dancing cakes, no music, no templates with somebody else’s characters on them. What carries the card is your photo and your sentence; everything else stays out of the way.
Pick the person and the occasion, write the text or have it drafted, choose a design and a photo — you end up with a link to send over WhatsApp, email or SMS.
No. The link opens a page with an envelope to tap — no app, no sign-up. After that they see your text, your photo and your name.
Yes. The digital card is part of the app; nothing is charged, and there is no advertising on the card.
The first opening is recorded, and your overview shows how many of your cards have been opened. For a single card it is not shown.
Not at the moment. The postal route is built but not switched on — until it is, the app does not offer it rather than make a promise it cannot keep.
