Need a WordPress plug-in

Looking for to make a WordPress plug-in


That plugin will has one page for setting
So user can activate it with their api key

The other part it will be on the post editor
In the editor elements or bar we will add a button

So user can write a text and after that he need to selected the text he want and with the button that we put in the bar we will send the selected text to the api link that we set with api key

And the api will back us with an out put text

That out put text should be automatically pasted after the selected text that we selected before.


Thanks
