WordPress saves all drafts.
Tyler asked me today to demonstrate how to view side-by-side drafts of his posts in WordPress’s Edit mode. I promised I would, then forgot to follow through. So here:
Find the Revisions table.
First, open your post in Edit. Down below the text field are a set of tables that include a list of hyperlinks to all the time-stamped drafts you’ve saved, or that WordPress has Autosaved for you.
Click any time stamp, the one you want if you recognize it, though any link will do. You can fine-tune your selection once you launch the function.
Click “Compare any two revisions.”
The double arrows above the side-by-side window will let you scroll through all your early drafts, comparing any two.
WordPress highlights the differences between your drafts.
