Slack Reviews & Product Details

Slack Overview
What is Slack?

Slack is the top choice for teams to communicate. It provides a virtual workspace that helps teams maintain open communication in a business environment. With Slack, users can host voice and video calls with up to 15 participants and even screen share with a desktop app, empowering better user interaction. Slack also supports options for private and group sessions, and one of its best features is Slack Huddles–an informal meeting space that lets you directly talk to your channel where you can share screen side by side with your team. The platform integrates well with Dropbox, Google Drive, and Trello as well.

"Slack for a distributed team"
What do you like best about Slack?

If we had to summarize, we'd say that we like the way Slack brings people together. There isn't one thing that does it. My team has realized that there are many detail-level design decisions that make Slack a very high quality product. Online communication in real time has been around for a looooong time. But Slack adds a certain polish to the UI that makes it a much more usable and enjoyable product.

What do you dislike about Slack?

There's not much we dislike, but if we were to have our way it would be easier to access audio or video conferencing. The online communication is great when you're just typing, but with a distributed team we really need audio and visual as well.

What problems is Slack solving and how is that benefiting you?

My team is scattered over 5 states, so the business problem we are solving is simply real-time team communication. Slack helps us do that whether the person be 1000 miles away, or 10 feet away in the office.

"A PROPER APP TO BE IN TOUCH WITH OUR TEAM AND PARTNERS"
What do you like best about Slack?

It works in real-time, and that keeps us connected despite the different time zones of each of us. Because we are a team in other countries, it's super respectful of the scope of privacy. Notifications can be perfectly organized and delimited. The ability to sort and prioritize messages and share files or paths. It is excellent.

What do you dislike about Slack?

When they update the app, it takes almost a day to work again 100%

What problems is Slack solving and how is that benefiting you?

We solve queries about ongoing projects on the spot. We also organized by teams, so we set up different communication groups. It gives us quick access to a highlighted message.

"Awesome Tool for Business Messaging"
What do you like best about Slack?

What I like best about Slack is its incredible ability to streamline communication and collaboration within our team. The platform offers a user-friendly experience that simplifies how we work together. The organization of conversations through channels is a game-changer. We can create channels for different projects, teams, or topics, which keeps discussions organized and accessible. It makes it easy for us to find specific conversations quickly.

What do you dislike about Slack?

I have to say that I haven't found anything to dislike about Slack. The platform has been incredibly effective and user-friendly for our team's needs. It has streamlined our communication and collaboration, making it a vital part of our workflow. Whether it's the organization of discussions, file sharing, integration capabilities, or the accessibility of the platform, Slack has consistently met and exceeded our expectations.

What problems is Slack solving and how is that benefiting you?

The fact that Slack is accessible on both desktop and mobile devices is incredibly convenient. It allows us to stay connected and productive, whether we're in the office or on the go. We had trouble with other tools that only worked on the web and were not accessible on mobile devices, we had to be on desktop all the time to access team conversations. Slack has allowed us to have a more seamless commuication across teams and we're all very satisfied.

"Slack: The Must-Have Tool for Effective Team Communication and Collaboration"
What do you like best about Slack?

Slack is simply amazing. It has provided us with a robust and reliable communication platform that has transformed the way we collaborate within our team. The organization into thematic channels makes navigation and finding relevant conversations easy, and the search capability is a true blessing when we need to track down old messages or files. The app integrations are great and have allowed us to easily connect our favorite tools, enhancing our overall productivity. I would definitely recommend Slack to any team looking to improve their communication and collaboration.

What do you dislike about Slack?

Slack is an incredible platform that has significantly improved our team's efficiency and communication. It's hard to find any faults with it, to be honest. The interface is user-friendly, the functionalities are robust, and the integration options are extensive. It has brought our team closer together, even when working remotely, and has streamlined our workflow in ways we never thought possible. I can confidently say that there's nothing I dislike about Slack. It has become an indispensable part of our daily operations.

What problems is Slack solving and how is that benefiting you?

Slack has been a game-changer for our team's communication struggles. Before implementing Slack, our internal communication was often scattered and chaotic, resulting in misinterpretations and missed deadlines. However, with Slack's intuitive interface and powerful features, we've managed to streamline our communication channels effectively. The ability to create different channels for various projects and departments has helped us keep our discussions organized and on track. Slack has undoubtedly contributed to fostering a more collaborative and productive work environment for us.

"Slack encourages focused team conversations."
What do you like best about Slack?

Slack's group team chat is my favorite part of this messaging platform. Team group chat encourages real-time communication, which makes it possible to reach colleagues across my organization instantly. The nature of chatting also works in favour of this style of communication , by making it possible for a recipient of a chat message to respond when most comfortable, or even respond while being engrossed in some other activity. The addition of the Channel feature , has only made group team chats a lot better. By making it possible to organize conversations by projects , departments or teams. Thereby ensuring that there is a home for every form of convcersation we may want to have.

What do you dislike about Slack?

I seldom rely on Slack's video communication provisions known as Huddles to communicate. This is because it lacks advanced features like background noise cancellation , background video images or optimized bandwidth suppression and so on, which are provisions that I have come to associate with standard video conferencing tools.

What problems is Slack solving and how is that benefiting you?

Slack makes everyone within my organization, to be only a message away from me and I find this very important for team productivity. Slack's channel provision makes our conversations very organized , making it easy to locate or reference specific conversations in future.

"Great for team use and one on one video"
What do you like best about Slack?

I like that I can have the whole team using Slack but also have protected channels and different channels for sharing information on a variety of topics. I also like that there is a Trello built in which allows easy access to our more visual "to-do" lists while we can still discuss and share files easily on Slack. I also like that I get to search my messages to access earlier messages or files. The editing feature also reduces to need to send multiple messages to correct spelling mistakes and reduces confusion! Finally, I like seeing who is online or not and who has their notifications off so I have a better idea of when to expect a response.

What do you dislike about Slack?

I dislike that the call quality can be low. Otherwise, it's great to have quick calls and increases efficiency in team communication- especially for quick check-ins and messages that don't need to be an email!

What problems is Slack solving and how is that benefiting you?

I am building an online work environment that is more similar to being in an office. For example we'll have work related channels but also a 'random' channel in which colleagues can share gifs, interesting news or non-work related information. It allows for both formal and informal communication.
