HTML Description multiline textbox with having Link for web address and email

Hi All ,

I get a situation where I need to create a Description box such as when user type a URL like (www.gmail.com or abc.com ,abc@gmail.com) it will automatically convert it into clickable link .

I try with the Jquery to replace  the URL or Email Link like <a href="abc.com">abc.com</a> but it's look like an HTML .

I also try with the CKeditor but didn't succeeded .

Please suggest 

Thank you
