Looking for right decision!

Hello,
I am looking for a chat application to implement it to my website. I don't have idea which to use or which is best. I came across Envolve and Chatwing but still looking for more options before I decide which to take.
Have in mind I want to be able to post youtube videos and charts into it and I also want to have option for design makeover plus Iphone and Android app access with alerts.
Thanks!!

Well I started researching on my own then. I made a lot of research in finding a chatroom for my website. Apparently envolve closed down when google bought them, pitty. I tried IRC but I truly did not like the look and feel and the “mess” of text in there. I had several points which are important to me.

1. First I needed a chat that can be seen in mobile (all versions) so I narrowed down the search for html5 chat room that look good on both mobile and pc.

2. I needed a custom design, I needed my background to be black or transparent. This was very hard to find (my site is dark).

3. I do not like to install the chat in my server as this is high CPU and resource consumer. So I need a chat service.

4. Lastly, I needed the ability to add You Tube videos and upload files (technical analysis).

I have checked several chats and only 1 met my needs, Chatwing.

I choose Chatwing finally as it can be integrated into my page and not only as toolbar but it has the Android and IOS app which no other service has.
