How It Works
Sweet Cocoa is incredibly easy to use. Visit the website, choose or create a character, and begin chatting.
The user inputs a message in a chatbox, and the AI responds as the selected character. The interaction flows like a natural conversation, and the tone or personality depends on the character you’re engaging with. The entire system operates client-side, ensuring a smooth and distraction-free experience.
There is no account creation, no API key required, and no storage of chats. Each session is ephemeral and private, making it ideal for anonymous, low-stakes creative interaction.
