##### What does this mean for users?
The aim is to provide an analogous ecosystem to email - one where you
can communicate with pretty much anyone, without caring what app or
server they are using, using whichever app & server you chose to use,
and a nice neutral identity system like an e-mail address or phone
and use a neutral identity system like an e-mail address or phone

Matrix standard. It's not actually incorporated anywhere at the moment
but we are looking at the best legal structure for the future. We are

Tox.im provides C APIs. As of October 2015 Tox doesn't seem to have an
answer yet for decentralised conversation history storage.
##### How does Matrix compare with something like Trillian or Pidgin?
Trillian and Pidgin and similar aggregating IM clients merge all your IM
activity into a single user experience. However, your history and
activity into a single app. However, your history and
identity is still fragmented across the networks. People can't find you
easily, and your historyisfragmented (other than on the device
wherethe client runs). And rather than being able to chose the right
app for the job when communicating with people, you arepushed towards
relying on a specific aggregation app.
Matrix lets you get the best of both worlds by linking to all the
different networks (XMPP, AIM, ICQ, Lync, Skype etc) on the serverside,
using bridges which can be run by anyone. Matrix then provides a simple
standard HTTP API to access any of these networks, and lets you choose
whichever client you prefer (either as a 'native' Matrix client or using
a non-Matrix client from one of the networks which has been bridged in).
##### What Matrix compliant apps are there?
None yet, other than our examples. It's early days :)
Quite a few, ranging from the glossy mass-market to the geeky command-line. There's even an emacs macro. Check out [https://matrix.org/blog/try-matrix-now] for the current

of how to use Matrix's client-server API tolet your app communicate
with users via Matrix. We're currently working out the best way to
integrate your application's existing identity system with Matrix.
If your app doesn't have any communication capability already, you'll want
to use one of the Matrix client SDKs to add it in. These come in different
levels of sophistication - ranging from a simple HTTP API wrapper (like matrix-js-sdk, matrix-ios-sdk or matrix-android-sdk)
through to reusable UI components (like matrix-react-sdk and matrix-ios-kit). Pick
the one for your platform, or a 3rd party one if none of the above work for you,
and get plugging it in. You'll probably also want to read the [Client-Server API
