Automatically creates a sequentially numbered post title of your choosing if the title is left blank when the post is published. The plugin keeps track of what number to use and increments the number every time you publish a post with a blank title. Additionally, the post slug/url will be updated to reflect the new title if the author did not specify one manually.
An options page is available to set the title you want to use or to tweak the incremental number, should it become necessary. This plugin is very basic and is not multi-user aware. If any author on the site publishes a post with a blank title, SequenTitle will do it’s song and dance.

This plugin generates POST Title from POST content automatically. Sometimes, you forget to write the title or sometimes you don’t want to write the title. It will generate the title for you. Or you can select a statement from your post content to be a title for the post using shortcodes [agt][/agt].
How does it work? 
If you leave the title field empty, only then this plugin will work. 
There are two different ways, this plugin works: – 
* Firstly it will search the content to check whether you have used [agt][/agt]shortcode or not. If used, it will make the wrapped line as title. 
* If you haven’t used shortcode in your post, it will automatically pick first 30 characters from the post and will use them as post title.
Currently this plugin is tested with latest wordpress version 4.1, but it should work with other versions also.
