Kopete – multi-protocol instant messaging client

Kopete is KDE’s instant messaging (IM) client released under an open source license. The software is designed to be modular and plugin based.

It allows you to communicate with your friends and colleagues using various instant messaging services including AIM, ICQ, Jabber, IRC, Gadu-Gadu, and more. It is designed to be a flexible and extensible multi-protocol system suitable for personal and enterprise use.

The goal of Kopete is to provide users with a single easy-to-use way to access all of their instant messaging systems. The interface puts people first, and is integrated with the system address book to let you access your contacts from other KDE applications. IM can be intrusive, but Kopete’s notification system can be tuned so that only important contacts interrupt you.

Kopete also features tools to enhance your IM, such as message encryption, archiving, and many other fun and useful effects.

Key Features:

  • Grouping messages within a window, with tabs for easy switching of conversations.
  • Accounts option allows user to log on with multiple accounts.
  • Alias nicknames for contacts.
  • Grouping different contacts who are really the same person as one meta contact.
  • Custom notifications for meta contacts.
  • KAddressBook and KMail integration.
  • Logging conversations supported using the History plugin.
  • Style chat window appearance via XSL and CSS.
  • Custom emoticons supported.
  • Custom notification feature pops up a notification, plays a sound, or sends contact a message based on contact’s status changes.
  • Spell checking on-the-fly in chats.
  • Support for AIM and ICQ file transfers.
  • Plugins such as alias, auto replace, contact notes, cryptography, highlight, history, KopeteLaTeX, nowlistening, otr, Statistics, texteffect, translator, and more.
  • Multiple independent “identities” for a single user.
