Universal chat layer for building bots and agents.
Chat SDK is a TypeScript software development kit for creating chat bots that work across services such as Slack, Microsoft Teams, Google Chat, Discord, Telegram, and WhatsApp. It lets developers write bot behavior once while using adapters for different messaging platforms, with support for events, interactive cards, modals, commands, files, and streamed AI responses. The catalogue includes skills and instructions for working with the SDK.
