At Appsmith, we use Notion to manage our content calendar. We also work with a few external agencies and freelancers for some of our content. It is impossible to create granular access control and develop a workflow on Notion to run the process smoothly and thus, as soon as Notion released their API, we decided to build an application that helps us manage our entire content management in one place while giving our collaborators the necessary access only.
Our application uses our Notion (mock) Table as a data source and lets you plant, submit, and edit articles on the application, while at the same time having a provision for integrating with an email service of your choice (we use SendGrid here) to send reminder emails or updates to people in the project.
