Natural language understanding

Natural language understanding (NLU) is the branch of AI that interprets the meaning and intent behind human language, not just the literal words. It lets software grasp what a person actually wants from how they phrase it.

NLU is what separates a real conversation from keyword matching. It figures out that “I need someone out to look at a leak tomorrow” is an urgent booking request, extracting the intent, the timing, and the detail rather than just hearing sounds.

It’s the comprehension layer of an AI receptionist. handlo uses natural language understanding to interpret each caller’s request, ask the right follow-ups, and qualify them correctly — so the brief you get reflects what the caller truly meant.
