Contentstack allows you to create a custom Sidebar Extension in your stack to analyze your entry content and recommend ideas.
Note: When working within specific branches, extensions added or created will be available only within that particular branch. For example, you are working within the development branch, and you add new Custom Sidebar Extensions to this branch. These custom sidebar extensions will be available only within the development branch. Refer to our Branch-specific Modules document for more information.
