SendaSmile turns a real memory into a personal greeting card before your coffee goes cold — and records the moment they open it.
Tell us who it's for and share one memory. That's it. Our AI writes something so personal it doesn't feel like AI at all.
When your card opens, the recipient can record their 15-second reaction. That clip comes back to you — with your card overlaid as a watermark. One tap shares it to TikTok or Stories.
Tell us who it's for and one thing that makes them smile. Takes under a minute.
Our AI crafts something genuinely personal from your memory. You approve every word.
They get a cinematic reveal. They react on camera. The moment comes back to you.
