Koishi is a cross-platform, extensive, high-performance chatbot framework.

The name and icon design are inspired from Komeiji Koishi, who is a character in Touhou Project. Komeiji Koishi manipulates the unconscious, which symbolizes the theme of a chatbot as well as the love of the Koishi developers for it.


Out-of-the-box Experience

Koishi provides an out-of-the-box console. Even zero-based users can build their own chatbots in a few minutes.

  • Plugin Marketplace. You could easily download and install plugins in the console without any programming knowledge
  • Multiple Platform Supports. Koishi supports mainstream chat platforms such as QQ, Telegram, and Discord. Data should be exchangeable between different platforms and accounts.
  • Real-time Monitoring. Monitor the running status or change the behavior of the chatbot anytime through the control panel, and even chat as the bot account itself
