Rocket Chat’s Basic functionalities

Search a channel

To search for channels and users, use the search bar under your account box. Alternatively you can press Ctrl/Cmd + k to access the search bar quickly.

A search will find channels (including the ones you are part of) and users. You can not search inside private channels.

When you click on a search result, the following can happen:

Create a channel

To create a channel, you need to click on the plus + button that is alongside the channel search bar.

A pop-up opens. You can set the name of that channel, choose if the channel is public or private, set the channel to read-only, broadcast the channel, and invite users.


You can react to messages with emojis.

To add a reaction to a message, go to the message, click on the smiley face icon on the right of the message and then choose an emoji.

You can see other user’s emoji reactions beneath the message. To react with the same emoji as another user, click the emoji. You can also remove your reaction by clicking on your emoji.

Reply to a message

Reply to a message to quote a message from another user. The reply automatically triggers a notification sent to the message’s original author.

There are two options for replies:

  1. Use Reply in Thread to start a new thread underneath the original message. Threads create a string of messages that quote the original.

  2. Use Reply in Direct Message to quote the original message in a direct message to that user.

Question quantum.bot

Quantum Bot is our AI teacher. You can ask her anything. To do that, you have to speak direcly to her by using @ quantum.bot in any channel of the Open Knowledge Base.

Please, be kind with Quantum Bot, she is still really young and does not know everything yet. Also, remember, she is an expert about data science and AI. She is not a search engine, tapping into what people (experts and non-experts) write on the Internet. The good news is that she is learning really fast, and you can help her.

Feed quantum.bot

To teach her something, you can just follow this link.


We hope this blog post helped you navigate Open Knowledge Base a little bit better. Remember this is collaborative platfom promoting peer learning, so we encourage everyone to help each other and continuously feed our AI teacher Quantum Bot.
