# Creating investigations

After [creating an investigation](/platform/user-guide/investigations/getting-started-with-investigations.md#creating-investigations), switch between **Visual editor** and **NQL editor** using the toggle at the top-left corner of the investigation page—to build the investigation query:

* Select [Visual editor](/platform/user-guide/investigations/creating-investigations/visual-editor.md) to use a graphical tool to build investigation queries.
* Select [NQL editor](/platform/user-guide/investigations/creating-investigations/nql-editor.md) to write investigation queries in [Nexthink Query Language (NQL)](https://docs.nexthink.com/platform/user-guide/nexthink-query-language-nql).

Alternatively, with the support of [Nexthink Assist](https://docs.nexthink.com/platform/user-guide/search-and-nexthink-assist/using-nexthink-assist#query-data-with-assist), you may build investigation queries without any prior knowledge of **Visual editor** or NQL.

{% hint style="info" %}
Install the [Nexthink Library Investigations starter](https://docs.nexthink.com/platform/library-packs/it-operations/investigations-starter-pack) pack with predefined investigations to quickly gain insights on common issues without manually writing NQL queries, or using Nexthink Assist or Visual editor to query data.
