Input and output components in Langflow
This category of components defines where data enters and exits your flow. They dynamically alter the Playground and can be renamed to facilitate building and maintaining your flows.
The difference between Chat Input and Text Input components is the output format, the number of configurable fields, and the way they are displayed in the Playground.
Chat Input​
This component collects user input from the chat.
The Chat Input component creates a Message object that includes the input text, sender information, session ID, file attachments, and styling properties. It can optionally store the message in a chat history and supports customization of the message appearance.
