The intelligence behind every right question. Zelinqa builds the NBQ Engine — the decision layer that tells any AI agent or application which question to ask next, so every conversation collects exactly what it needs.
The NBQ Engine (Next Best Question Engine) is a service that returns the single most relevant question to ask a user at each turn of a conversation. Instead of building your own question-routing logic, your application calls one API endpoint and the engine decides — in real time — which question to ask next, based on what has already been said and what you still need to learn.

​
How it works

1

Configure in the NBQ Studio

Your team sets up questions, rules, and behavior in the Zelinqa NBQ Studio — no coding required.
2

Your application calls the API

Each time your application needs to ask the user something, it sends the current conversation context to the NBQ Engine.
3

The engine returns the best question

The API responds with the most relevant next question, or signals that the conversation is complete.

​
Two components

NBQ Studio

A no-code web interface where your team configures questions, rules, tone, and generates API keys.

API

A single stateless REST endpoint your developers call to get the next question in real time.

​
Key facts

  • The API is stateless — you send the full conversation context with every request.
  • The engine returns one question per call, the most relevant one.
You do not need to write any question-selection logic. The NBQ Engine handles that based on your NBQ Studio configuration.
