«Wp-autosave» plugin is for automatically saving posts being written in the Classic Editor
Note: This plugin works as an additional module to the Classic Editor plugin by WordPress Contributors since WordPress version 5.0+, 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.

(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
