What Is Slack?

Slack is where work happens for millions of people everyday. Slack transforms how work happens by bringing AI and automation to where people are already collaborating. Go from chatting with your teams to chatting with apps and data. Break down siloed data through Slack's searchable channel architecture, allowing your teams and AI to access your organization's knowledge. Teams work together in context when CRM data, project management, and people all come together to solve problems and make decisions. Teams can talk to each other and their AI agent in conversational language, allowing them to access each other and information seamlessly. Slack AI recaps channels and summarizes threads so that employees can jump into discussion quickly, whether they are new to a project or catching up after being away. Enterprise applications can easily be integrated and shared in channel and direct message, giving a snapshot of context and the opportunity to collaborate on the spot.

Implementing Slack at work was an absolute decision

5.0 4 years ago

Comments: We implement slack for inter-office communications. Slack made the communication possible and managing workflows was a lot easier. We often use slack for real-time messaging not, particularly for archives. Overall, slack has enhanced our business productivity, collaboration between project teams, and managed to provide streamlined communication.

Pros:

Slack was easy to use and implement at work. The web version of slack works completely fine. The slack interface is streamlined and ideal for business communication. We are able to replace emails at work and use communication on slack, which is quick and easy for project teams. The most significant thing I loved about Slack is, it can be integrated with other productivity, communication, and collaboration tools to make the work more streamlined and can be an optimum choice for automation and scripting.

Cons:

The only downside to this application is its pricing. The standard plans lack most of the important features, so we thought of upgrading to Plus. Since the price is based on per person per month, we found the pricing for Plus too high. So, we had expected if the price could be pay-per-module, but that can’t be helped either.

Alternatives Considered: monday.com

Reasons for Choosing Slack: Salesforce has lot of complexities at work and all we need is an easy and efficient tool to beat the performance. And we found Slack worthy of it.

Switched From: Salesforce Sales Cloud

Reasons for Switching to Slack: Slack is easy to use and implement at work. Well, it has ability to integrate with lots of apps, and outruns all other alternative applications in performance.

Slack is great for work groups

4.0 3 weeks ago New

Comments: I’ve used Slack for years now and I love the ease of use. I love how I can quickly brainstorm something for the group and leave it in the chat or schedule it to be delivered when everyone is available.

Pros:

I love that it’s fairly easy to use for beginners once you get the hang of it. I love that you can add photos, links, attachments, etc to messages and groups within Slack and you can also have multiple accounts for different businesses, work, school, and clients. I love that it has an app so that I am able to use it on the go from my phone, tablet, or laptop. I love that you can silence or stop notifications and getting messages at a certain time until the next day. It helps you keep work and home separate as well because you aren’t constantly getting notifications after hours if you use it for work.

Cons:

I don’t really have any issues that I can complain about right now. Everything I needed Slack for it worked great.

The original is better

2.0 2 months ago New

Pros:

A good centralized place for employees to gain information about the workplace, kinda similar to discord with the ability to make channels for specific criteria

Cons:

Kinda unoriginal and generally subpar compared to Discord, a lot of the features have been executed better elsewhere than here

Great option for team communication

5.0 3 months ago

Pros:

I really like that I can sync automations with Monday. And I can also manage permissions for everything, that way we can have multiple channels with the persons we want to.

Cons:

I dont have anything to complain about Slack, it is being really useful. We can communicate with the entire team, and it helps a lot the remote workers to stay connected with the office.

Slack for the everyday user

5.0 2 weeks ago New

Comments: Slack is wonderful—it’s never a question of its usefulness. It gives our team the opportunity to grow, connect, and collaborate effortlessly. Slack is easy to train on and lets you show off your personality. It also has many hacks and tricks that most people don’t know about, like setting reminders, sharing a GIF instantly, and mentioning individuals, only those online, or an entire channel. It’s a smart system that I love using.

Pros:

The ease of communication between teams, colleagues, and even adding a second or third company is so easy. I also love how easy it is to start a 'video call' huddle with anyone in your organization. With one click, you’re chatting over video, sharing your screen, and connecting with someone on the other side of the world. It also integrates very well with Zapier, Google, Asana, Calendly and many more.

Cons:

I'm not sure if this is a Slack issue or a user issue. I’m an Apple product fanatic; however, when my Slack is buzzing with notifications from all the workflows and channels I’m in, my phone, laptop, and watch all go off simultaneously, which can be overstimulating. Although I’ve turned off notifications on my watch (for my sanity), there are times I wish only certain channels would communicate to it.
