title: Susi - Docs


SUSI AI is an intelligent Open Source personal assistant. It is capable of chat and voice interaction and by using APIS to perform actions such as music playback, making to-do lists, setting alarms, streaming podcasts, playing audiobooks, and providing weather, traffic, and other real time information. Additional functionalities can be added as console services using external APIs. Susi AI is able to answer questions and depending on the context will ask for additional information in order to perform a desired outcome. The core of the assistant is the SUSI AI server that holds the "ingelligence" and "personality" of SUSI. The Android and web applications make use of the APIs to access information from a hosted server.

An automatic deployment from the development branch at GitHub is available for tests here

How do I install Susi: Download, Build, Run

Note: You must be logged in to Docker Cloud for the button to work correctly. If you are not logged in, you’ll see a 404 error instead.

At this time, Susi is not provided in compiled form, you easily build it yourself. It's not difficult and done in one minute! The source code is hosted at, you can download it and run Susi with:

> git clone
> cd susi_server
> ant
> bin/

For Windows Users (who are using GitBash/Cygwin or any terminal):
> git clone
> cd susi_server
> git checkout master
> ant jar
> java -jar dist/susiserver.jar
> git checkout development
> ant jar
> java -jar dist/susiserver.jar

To stop:
> Press Ctrl+C

After all server processes are running, Susi tries to open a browser page itself. If that does not happen, just open http://localhost:4000; if you made the installation on a headless or remote server, then replace 'localhost' with your server name.

To stop Susi, run: (this will block until the server has actually terminated)

> bin/

A self-upgrading process is available which must be triggered by a shell command. Just run:

> bin/

Where can I report bugs and make feature requests?

This project is considered a community work. The development crew consist of YOU too. I am very thankful for pull request. So if you discovered that something can be enhanced, please do it yourself and make a pull request. If you find a bug, please try to fix it. If you report a bug to me I will possibly consider it but at the very end of a giant, always growing heap of work. The best chance for you to get things done is to try it yourself. Our issue tracker is here.

Development Workflow

Fixing issues

Step 1: Pick an issue to fix

After selecting the issue

1.Comment on the issue saying you are working on the issue.

2.We except you to discuuss the approach either by commenting or in the gitter.

3.Updates or progress on the issue would be nice.

Step 2: Branch policy<br>

Start off from your development branch and make sure it is up-to-date with the latest version of the committer repo's
development branch. Make sure you are working in development branch only.<br>
git pull upstream development

If you have not added upstream follow the steps given here.

Step 3: Coding Policy

  • Please help us follow the best practice to make it easy for the reviewer as well as the contributor.
    We want to focus on the code quality more than on managing pull request ethics.

  • Single commit per pull request

  • Reference the issue numbers in the commit message. Follow the pattern Fixes #

  • Follow uniform design practices. The design language must be consistent throughout the app.

  • The pull request will not get merged until and unless the commits are squashed.
    In case there are multiple commits on the PR, the commit author needs to squash them and
    not the maintainers cherrypicking and merging squashes.

  • If you don't know what does squashing of commits is read from here.

  • If the PR is related to any front end change, please attach relevant screenshots in the pull request description

Step 4: Submitting a PR

Once a PR is opened, try and complete it within 2 weeks, or at least stay actively working on it.
Inactivity for a long period may necessitate a closure of the PR. As mentioned earlier updates would be nice.

Step 5: Code Review

Your code will be reviewed, in this sequence, by:

  • Travis CI: by building and running tests.<br>
    If there are failed tests, the build will be marked as a failure.
    You can consult the CI log to find which tests.<br>
    Ensure that all tests pass before triggering another build.
  • The CI log will also contain the command that will enable running the failed tests locally.<br>
  • Reviewer: A core team member will be assigned to the PR as its reviewer, who will approve your PR or he will suggest changes.

Have fun!
