Virtual data assistant

The virtual data assistant (ViDA) is an interactive tool that users can 'chat' to. It helps users find published NHS Digital data, and can answer questions about our data and information processes.

The virtual data assistant is in beta

This means that it is still the first version, and we are still testing it. Some results might not be exactly as you expect.


We'd like to hear about any unexpected results that you get. Please email us at

What the assistant does

The virtual data assistant is a chat bot that you can ask questions about NHS Digital's data and information.

You can ask it questions about:

  • information on data we publish
  • health statistics and indicators
  • the process for accessing data

For example, you can ask questions like "can you show me data about A&E waiting times?" or "what is a data access request?".


What the assistant cannot do

The assistant is only able to help with questions about data and information from NHS Digital.

It cannot provide health advice, or answer questions about any individual's data. If you need medical advice, speak to a health professional or call NHS 111.


This beta service requires Javascript in order to work, which isn't suitable for all users.

It does not currently meet the accessibility standards of the current site.

If the tool is successful, we will look at accessibility prior to launching the full live service.
