Slack Key Features

Below, we'll discuss the key features of Slack, and how they can benefit your business. We'll discuss usability and customer service availability as well. Throughout the review, we'll include images of the software to give you a sense of what it's like to use Slack.

Chat Workspace

Teams typically use Slack to discuss and share files in one central location, known as their workspace. Each workspace is typically organized into various "channels", which are topic-focused chat rooms.

For example, your workspace may be divided into team-focused channels where members of that team can discuss their shared projects and tasks. As you can see in the image below, the workspace is divided into channels, which are identified by the "#" symbol.

Slack review channels

Channels can be public, meaning that any member of your workspace can search and join them, or private. Private channels are only accessible to members who have been invited to that channel. This helps further categorize the way that information is shared and discussed across a company. Channels that are private are indicated by padlock icons.

Voice & Video Calls

In addition to its real-time chat features, Slack also includes built-in video chat and phone calling functionality. This allows users to easily transition from a chat to communicate through other mediums when necessary. During a video call, you can also use screen sharing to illustrate what you're talking about.

Though Slack is primarily focused on developing features for chat-based communication, and therefore the video conferencing capabilities are not quite as robust as Skype or Google Meet. If you need to integrate a more developed video system, Slack has native integrations with Zoom, BlueJeans, and more.


Slack includes a default bot called the Slackbot, which answers questions about Slack features, will automatically respond to default slash commands, and can respond to reminders. For example, you can use the "/remind" slash command to trigger the Slackbot to create a reminder.

Let's say that you send the Slackbot a message with the following text: "/remind Amy about the meeting at 3PM tomorrow." The Slackbot will automatically respond with a message that confirms that it will remind you to notify Amy at that time, as shown below. You can also create your own custom slash commands to either trigger an action in another application.

Slackbot Reminders

To message the Slackbot, send messages in your own personal chat.


Slack is designed to be used in combination with many of your team's existing tools, ranging from G Suite applications like Google Calendar to project management tools. Users can customize their Slack workspace by making these tools easily accessible within direct messages and channels, which means that they won't have to switch back and forth between applications during a conversation.

Here is a list of the major tools that Slack has native integrations with.

Customization Options & API

Slack provides technical users an API in order to encourage teams to build Slack apps. For this reason, it has gained a following among tech companies that have software developers who can use the API to make Slack serve their exact use case more efficiently.

Slack API

Slack's API makes it possible for software developers to create custom integrations that react to certain snippets or terminology throughout their teams' conversations. This means that potentially you can custom applications or control specific parts of your workflow right from Slack.

Slack Customer Support

Slack offers many self-help service options for customers like their blog, demo videos, a Help Center, and specific portals for developers and Slack partners.

Slack also offers live chat on their website, so you can instantly get in touch with a member of the support team. Customers can also fill out a form on the website to be contacted via email.

Slack Alternatives & Competitors

Slack is similar to other business communication platforms like Microsoft Teams. While it doesn't have many direct competitors, alternative software platforms like Skype and Google Meet have chat functions built in.

Is Slack Right For You?

If you're looking for a real-time communication platform that integrates with your existing business applications, and helps drive more effective conversations within and across teams in your organization, then Slack is the best option on the market.

Slack has gained a reputation for facilitating communication and increasing productivity in the workplace. It offers an impressive number of integrations with widely used applications, including business applications like G Suite by Google and Microsoft Office 365, as well as project management tools like Trello and Asana. These integrations, as well as Slack's support for creating custom integrations, have enabled Slack to fit neatly into many companies' existing workflows.
