Release version: Brazil  
Updated September 10, 2026  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read  
Use knowledge blocks to simplify knowledge authoring for writers and knowledge consumption for readers.
* **[Create a knowledge block](https://www.servicenow.com/docs/mNQZcZx4E2MXw0CFt_GQKQ)**   
  Create or modify a knowledge block to define a reusable piece of content that can be inserted into knowledge articles in a knowledge base. The knowledge block is secured by user criteria, which controls what users, groups, roles, companies, locations, or departments can read or not read the content in an article or search, enabling users to more easily view content that is relevant to them.
* **[Add knowledge blocks to a knowledge article](https://www.servicenow.com/docs/Bcx8L8PVhcEmecLOarCzGA)**   
  You can insert one or more knowledge blocks into a knowledge article within a knowledge base. Each knowledge block is secured by user criteria, which controls who can read or not read the content in an article.
* **[Preview a knowledge article with knowledge blocks](https://www.servicenow.com/docs/vmPOWpdpgX9YLNuziyBi2g)**   
  Preview knowledge articles by user or date. For unpublished articles, impersonate different users to see how blocks display based on user criteria. For published articles, preview by user and date to see past versions.
* **[Integrating a custom search or knowledge article viewer with knowledge blocks](https://www.servicenow.com/docs/Nv88IUtMSo07Pig4K1DgBQ)**   
  If you are using a custom search or knowledge article viewer with your application, you can integrate that custom search or viewer with the appropriate knowledge or knowledge blocks API.
