5.2.3 Output nodes

Output nodes deliver the assistant’s response — either as composed text or as the result of custom code.

The Output node in the BlockFlow designer.

Output Text node

Sends text-based responses to the user — the voice of the assistant. It:

• displays static or dynamic text;
• supports placeholders replaced with real-time data;
• responds in multiple languages;
• allows basic rich-text formatting;
• works together with input nodes to acknowledge user input.

Assistant  "What is your name?"
User       "Maria"
Output     "Hello, Maria! How can I help you today?"

Output JavaScript node

Generates responses with custom JavaScript rather than templates. It supports:

• custom logic (a greeting based on the time of day);
• real-time processing of input data, variables or API responses;
• conditional output;
• integration with external systems;
• reusable functions defined inside the node.
