Editing Psi (instant messaging client) (section)

== Features ==
Because XMPP allows gateways to other services, which many servers support, it can also connect to [[Yahoo! Messenger|Yahoo!]], [[AOL Instant Messenger|AIM]], [[Gadu-Gadu]], [[ICQ]] and [[Microsoft Messenger service|Microsoft]] networks.<ref>{{cite web |url=http://www.softpedia.com/reviews/linux/Psi-Review-55917.shtml |title=Psi Review |first=Roxana |last=Popa |work=[[Softpedia]] |date=May 29, 2007 |access-date=January 24, 2012 }}</ref> Other services available using gateway servers include [[RSS (file format)|RSS]] and [[Atom (standard)|Atom]] news feeds, sending [[Short message service|SMS]] messages to cellular networks and weather reports.

As of 2012, Psi has language packs for 20 languages, with more being created.<ref>{{cite web |url=http://news.softpedia.com/news/Best-5-Jabber-Clients-for-Windows-in-Pictures-86636.shtml |title=Best 5 Jabber Clients for Windows in Pictures |first=Bogdan |last=Popa |work=[[Softpedia]] |date=March 27, 2008 |access-date=January 24, 2012 }}</ref>

[[Emoticon]] packs are supported using the [[Jisp (icons)|jisp]] format. Many jisp emoticon packs are available, including ones from AIM, [[iChat]], and [[Trillian (instant messenger)|Trillian]].

Psi supports file transfers between other XMPP clients, and it is possible to send to or receive files from other [[Instant messenger|IM]] networks, if the user's servers support this. Psi supports Contact Is Typing Notification (which works with Yahoo!, MSN, and AIM contacts). Version 0.10, released in January 2006, brought automatically resizing contact list and composing window in chat dialogs, tabbed chats, support for Growl messaging system on [[Mac OS X]], window transparency and many other changes.

Support of audio and video calls in Psi via [[Jingle_(protocol)|Jingle]] is implemented via officially supported plugin PsiMedia.<ref>[https://github.com/psi-im/psimedia PsiMedia]</ref>

=== Encryption ===
Security is also a major consideration, and Psi provides it for both client-to-server (TLS) and client-to-client ([[OpenPGP]],<ref>[https://github.com/psi-im/plugins/tree/master/generic/openpgpplugin OpenPGP Plugin]</ref> [[Off-the-Record Messaging|OTR]],<ref>[https://github.com/psi-im/plugins/tree/master/generic/otrplugin OTR Plugin]</ref> and [[OMEMO]]<ref>[https://github.com/psi-im/plugins/tree/master/generic/omemoplugin OMEMO Plugin]</ref>) via appropriate plugins. Encryption of messages in group chats is supported only via [[OMEMO]] plugin.
