Strive is a content calendar plugin for WordPress. It is one of the best options in the segment. You can use Strive to manage the schedules of the content creation on your WordPress website. Strive comes with five key features: Content Calendar itself, Pipeline View, Post Statuses, Post Checklists, and Revisions.
Strive is especially a great plugin if you have a WordPress website with multiple authors whereby you are responsible to manage them. You can use it to schedule the content creation and assign each task (content creation) to an existing user. To make each task clearer, you can add pre-defined parameters such as post category and post tag. You can even insert a draft to a task. The ability to add a note is another worth-mentioning feature. You can use this feature to — for instance — add reference links.
Here are the key features offered by Strive:
Content Calendar
Content Calendar is the main feature that Strive offers. With the feature, you can schedule the content creation on your website so that you will have a very-organized content creation workflow. The process of scheduling content creation itself is extremely easy and enjoyable thanks to the visual interface of Strive.
Not only you use Strive to schedule the creation of blog posts (default post type), but also custom post type.

Pipeline View
In Strive, you have two options to view the content creation schedules: Calendar View and Pipeline View. Content Calendar View only shows the content creation schedules. If you want to view the unfinished drafts on your website (before you install Strive), you can do so from Pipeline View.
In Pipeline View, you can view all the unpublished content along with the post status (not started, being written, being edited, and complete).

Post Statuses
The Post Statuses feature makes it easier for you to track the progress of the content creation. This feature is pretty useful for content manager. You can check the post statuses whether on Calendar View or Pipeline View. To check the status of a post on Calendar View, you can simply notice the color. If a post has a green color, this indicates that the post is done. Here are the color codes of the post statuses:
- Red: Not started yet
- Orange: Being written
- Yellow: Being edited
- Green: Done

Post Checklists
Creating content requires several steps. From conducting research, writing, and editing. Each step also involves other steps. For instance, when editing the content, you typically making sure things like keyword and image are not missed.
You can easily miss a step on your content creation if you create checklists. The Post Checklists feature from Strive helps avoiding it. Strive itself comes with four pre-made checklists whereby each checklist contains several items (tasks). The checklists are editable. You can simply add a new item if you want.

Revisions
To make old content keeps relevant, you can edit it. Strive comes with a Revisions feature to allow to effortlessly schedule content revision just like content creation.

Strive works on both Gutenberg (block editor) and Classic Editor.
