wpautosave

“Wp-autosave” plugin is for automatically saving posts being written in the Classic Editor
Note: 
This plugin works as an additional module to the <a href="https://wordpress.org/plugins/classic-editor/" rel="ugc">Classic Editor</a> plugin by <a href="https://github.com/WordPress/classic-editor/" rel="nofollow ugc">WordPress Contributors</a> since <a href="https://wordpress.org/support/wordpress-version/version-5-0/" rel="ugc">WordPress version 5.0+</a>, because the original Classic Editor was replaced with a new editor – Gutenberg. 
So the original Classic Editor plugin is required to work with WP-Autosave plugin for all actual WordPress versions.
In case of older versions of WordPress (<5.0), the original Classic Editor plugin is not required because Classic Editor is used by default.
Major features of plugin: 
– Auto-save post to drafts at regular time intervals by multipart requests. (To check the functionality it’s enough to have the rights to create an entry in the wp-blog (you can test through a user-account) – you will see all requests through the developer tools or some other tools) 
– Intellectual immediately auto-save post to drafts when you change the text in the editor 
– You can attach a time-stamp to request through the settings of the plugin (appendix time of saving in the query) 
– You can set your auto-save interval 
– You can choose the type of saving – by time intervals or when content is changed
