Classify Text maps a string to categories you define. It returns both the
selected category name and a boolean output for every configured category, so
downstream branches do not need to compare strings.
Each category contains:
- Key — The exact string returned by the model.
- Description — Optional guidance that distinguishes this category.
Category keys must be unique. Use short, stable keys such as billing or
security; put nuance in the description.
Outputs
Single category
Multiple categories
Selected Category contains one category key. Each configured category
also creates an Is “key” boolean output.
Selected Categories contains a list of keys. Every Is “key” output
indicates whether that category was selected.
Example: route inbound email
Enable Other so unrelated messages have a safe route. Leave multiple
categories off when every email must have one owning queue.
