## What it is
Chat SDK is a unified TypeScript SDK for building chat bots and AI agents that run across Slack, Microsoft Teams, Google Chat, Discord, Telegram, WhatsApp, and more from a single codebase. It provides type-safe event handlers, JSX-based interactive cards, LLM response streaming, and pluggable adapters and state backends (e.g., Redis) for serverless deployment.

## Use cases
- build a chatbot that works on slack and teams with one codebase
- stream llm responses into slack messages
- handle slash commands and modals across chat platforms
- create an ai agent bot for discord
- deploy a serverless chat bot with redis state
- send interactive cards and buttons in google chat
- scaffold a next.js chat bot app

## When to choose
- you need one bot logic deployed to multiple chat platforms
- you want type-safe handlers and JSX cards instead of raw platform APIs
- you are streaming LLM/agent responses into chat threads
- you deploy on serverless and need distributed state and deduplication

## When to avoid
- you target a single platform and prefer its official first-party SDK
- you need platforms without an available adapter
- you want a no-code or hosted bot builder rather than a code SDK
