Features
A Softpedia review of QIP 2006 mentioned its unique feature (at the time) of tabbed message windows—instead of a message window for each chat session, one window with several tabs is shown. Since this feature's introduction, ICQ Version 6.0 now includes this feature, as do the multi-service clients Pidgin, Miranda NG, and Trillian. Other features include integrated mail.ru e-mail client, and a wider range of emoticons. QIP presents no advertisements in the application windows; this is described as a security advantage.

QIP 2005
QIP 2005 was an alternative instant messaging client based on the OSCAR protocol. It has full support of ICQ and experimental support of AIM.

QIP 2005 did not properly support Unicode which caused issues when sending and receiving non-ASCII messages unless both users use QIP.

QIP Infium
QIP Infium was the second version of QIP. It features full Unicode support and is multi-protocol client, supporting the following protocols:
 * OSCAR: ICQ
 * XMPP, first stolen and only then licensed on Miranda NG Jabber Plug-in with preinstalled settings for QIP, LiveJournal, Google Talk
 * XIMSS (CommuniGate Pro IM and VoIP protocol) with preinstalled settings for QIP, SIPNET and Euroset
 * Mail.ru Agent
 * IRC (Additional plugin)

QIP 2010
New version of QIP named QIP 2010 contained all features of Infium and interface of QIP 2005.

QIP Infium would attempt to reset Internet Explorer to use the search engine at the QIP homepage via OpenCandy. This feature could be disabled on the first attempt or by using the Add-on Manager under the Tools menu of Internet Explorer.
