Overview
Sekai is positioned as a roleplay and companion AI product. After creating or selecting a character through the website, users enter a chat interface to interact. The main usage pattern is text input conversations with characters, and the characters respond according to their settings. Its core strength is support for freely unfolding roleplay scenarios, making it suitable for users who enjoy fictional stories or everyday companionship. Compared with similar products, it places more emphasis on the flexibility of character setup and the directness of the chat interface, rather than on multimodal features or community sharing.
