Consent before cloning
Every voice profile begins with the speaker recording their own clip.

A gift, not a gimmick
Names, lyrics, and styles make every performance feel intentionally made.
03
Easy on both sides
Send a link. They watch instantly—then can create their own if inspired.
From breath to birthday
Ten seconds in. A full performance out.
BirthSlay keeps the clever technology backstage so making the card feels as simple as sending a voice note.
