### Answer To save text from a conversation as a variable, use the Extract Dynamic Variable Node in your conversation flow. [(1) ]() ## How to set it up: 1. Add an Extract Dynamic Variable Node to your flow 2. Create a variable by filling in: - Variable Name – A short name to reference this variable (e.g.,

customer_name

) - Description – A brief explanation of what this value should be - Variable Type – Choose

Text

for text values ## Variable Types available: - Text - Any word or sentence (e.g.,

"headache"

,

"John Smith"

) - Number - A numeric value (e.g.,

42

,

98.6

) - Enum - A value from a predefined list - Boolean - True or false Once extracted, you can reference the variable elsewhere in your flow using the

{{variable_name}}

syntax. [(2) ]()

@AI Evy Should i just say in a conversation node to save EXAMPLE as {{variablename}} would that do the same?

### Answer No, simply writing "save EXAMPLE as {{variablename}}" in a conversation node prompt won't reliably extract and store information as a dynamic variable. The Extract Dynamic Variable Node is specifically designed for this purpose—it extracts information from the conversation and stores it as a dynamic variable. [(1) ]() Here's the difference: -

{{variablename}}

syntax is for referencing or injecting existing variable values into prompts, begin messages, tool configurations, etc. [(2) ]() - Extract Dynamic Variable Node is for extracting and saving information from the conversation into a variable that you can then reference later. [(1) ]() To properly save extracted text as a variable: 1. Use the Extract Dynamic Variable Node 2. Define the variable name, description, and type (Text, Number, Enum, or Boolean) Once saved, you can then reference that variable anywhere using

{{variablename}}

. [(2) ]()
