# Using AppInstanceBots as intelligent channel agents for Amazon Chime SDK messaging
<a name="appinstance-bots"></a>

You can use `AppInstanceBots` as intelligent channel agents. The agents recognize key phrases sent via `ChannelMessages` by channel members. The bot's natural language understanding model resolves the messages. In turn, that allows one or more channel members to engage in a natural language dialog defined by the bot's model. You supply the bots, so you control the depth of dialog and integration with your enterprise systems.

**Prerequisites**
+ Knowledge of basic Amazon Chime SDK functionality, such as creating `AppInstanceUsers`, managing channels, and sending and receiving messages.
+ The ability to invoke the Amazon Chime SDK Messaging APIs.
+ Knowledge of basic Amazon Lex V2 functionality, such as creating an Amazon Lex V2 Bot, modeling intents and slots, creating bot versions, aliases, using session state, and Lambda hook integration.

**Important**  
Use of Amazon Lex V2 is subject to the [AWS Service Terms](https://aws.amazon.com/service-terms/), including the terms specific to the AWS Machine Learning and Artificial Intelligence Services.
