their photo, or your thing together
Pick a starting point
Every friendship has a thing. The corner table you always get, the game night that runs too late, the lake every summer. Type that, and the AI designs a birthday card around exactly it. A photo works too, theirs or one of the two of you: they land in the scene and still look like themselves. Make it on this page, then print it at home or send it from your phone before you forget.

How the card gets made
Start with them
A clear photo of their face, a photo of the two of you, or one line about the thing you two always do. Any one of those is enough.
It gets painted
With a photo, they land in a new scene and still look like themselves, both of you if you are both in it. Without one, your thing becomes the card: a watercolor, a cut-paper scene, a poster.
Fold it or send it
The print-ready PDF comes by email and folds into a real card with the inside blank. Or save the image and text it to them tonight. Print guide →
What to write to your best friend
The front is the art. The inside is blank, so the words are yours and so is the handwriting. A few lines that have worked between friends who go back a while. Take one if you are stuck, or write the thing only the two of you would get.
- “happy birthday to the only person who has seen every version of me and stayed”
- “you are the family I picked. happy birthday”
- “another year of you answering on the first ring. happy birthday, friend”
- “we have been friends so long we are basically each other's emergency contact. happy birthday”
- “happy birthday. the usual spot, my treat, no arguing”
- “I know too much about you for us to ever stop being friends. happy birthday”

Frequently asked
Does it work for a guy friend or a girl friend?+
Either. The page never says he or she, and the card is built from what you type, so a best friend of forty years and a best friend from freshman year get different cards. Type the thing you two always do, or upload their photo.
Can I use a photo of the two of us?+
Yes, and it is the photo most people use here. Both of you are drawn into the new scene, each recognizable, nobody added and nobody cut. A clear photo where both faces are easy to see works best.
Can our inside joke be on the card?+
Type it. The front line is whatever you write, and the details box shapes the scene around it, so the joke lands without anyone else getting it. For a card that puts their face in the joke, the funny birthday cards page does that.
Can the card be from the whole group?+
Yes. The front carries one line, the inside stays blank so everyone can sign it, and the image can be texted to the group chat so each person sends their own.
Artistic or Fun: which one?+
Artistic draws the thing you two do as itself: a storybook watercolor, a cut-paper scene, a screen-print poster or a travel poster of your place. Fun gives it faces and lets it throw the party. Artistic is the first card on the style screen.
Is it free?+
Making a card is free. Make the card right here and it is yours to download. No account, nothing watermarked.
Print it, or text it to them?+
Both. The print-ready PDF comes by email and prints on cardstock, folded once, with the inside blank for your own words. Or save the image and text it, which is how most best friend cards travel.
Which AI model makes these cards?+
The same one behind every card on this site: OpenAI's gpt-image-2.5 image model, since September 16, 2026 (before that, gpt-image-2). A vision model reads their photo or the thing you two do first, then gpt-image-2.5 draws the card. Since September 19, 2026 every card renders at the model's highest quality setting, the one that best keeps a face true to the photo you upload.
