A widget that lists your most recent posts with excerpts, optionally limited to a category. The number of posts and excerpts is configurable; for example, you could show the titles of five posts but include the excerpt for only the two most recent. Supports <a href="http://robsnotebook.com/the-excerpt-reloaded/" rel="nofollow ugc">the_excerpt Reloaded</a> and <a href="http://sparepencil.com/code/advanced-excerpt/" rel="nofollow ugc">Advanced Excerpt</a> for excerpts with HTML formatting.
New! Supports displaying post thumbnails along with excerpts. Widget options let you place the thumbnails above the title, in between the title and the excerpt, or below the excerpt.

Created to help those people who don’t like to edit code in template files (or are too lazy to do that). 
Just activate the plugin and it will automatically show the_excerpts in your homepage, archives and search results. 
It tries to display your custom excerpt text and if it doesn’t find it it will show an automatically generated excerpt. 
You can also define excerpt length, custom read more link and attach a thumbnail.

Auto Excerpt everywhere

Thanks to author for creating this plugin. 
It's works out of box. And working fine at WordPress Version 4.6.1


Works out of the box on WP Version 4.6.1

The plugin automatically displays excerpts instead of full post contents in your blog. Custom excerpts and generated excerpts supported.
