Plans supporting this feature: Business Enterprise
Custom fields allow you to attach additional structured fields to articles, page categories, decision trees, and API documentation. Instead of relying only on default metadata such as tags, SEO title, or description, custom fields enable users with appropriate permissions to define their own fields and capture information that is specific to their documentation.
For example, a product documentation team may want to add fields such as Product version, Feature owner, Release status, or Content review date. These fields can be created at the project level and then configured at the article level.
Custom fields help teams organize content more effectively, maintain consistent data across articles, and support integrations that require structured information from the knowledge base.
