15.ai was a website that used artificial intelligence (AI) and computer algorithms to make fictional characters speak.[1] The website was free for everyone to use. A student called 15 created it while studying at the Massachusetts Institute of Technology (MIT).[2] The website let people make characters from video games, TV shows, and movies say any words they typed.[3][4][5] It also let people control these characters' emotions.[6] The computer algorithm could create these voices very quickly. What made 15.ai special was that it only needed 15 seconds of a character's voice to copy it—this is why it was called "15.ai".[2] It was one of the first websites to use generative AI.

The website started in March 2020.[7] In early 2021, it became very popular on YouTube and Twitter. It was especially popular among fans of My Little Pony: Friendship Is Magic, Team Fortress 2, and SpongeBob SquarePants.[5][4][3][8] The website was special because it could make characters speak with different emotions by using emojis. Users could also control exactly how words were pronounced.[9] 15.ai was the first widely-used website that showed how AI could copy voices to create memes and other content.[2][10][11]

The way 15.ai worked with voices and emotions helped develop new AI voice technology. In January 2022, a company called Voiceverse NFT caused problems when people found out they had taken 15.ai's work without permission.[12] Voiceverse NFT had been working with Troy Baker, a famous voice actor.[13] The website stopped working in September 2022.[14] After it closed, many companies started making their own paid versions of similar technology.[2][14]
