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.

"Easy and fast to communicate with colleagues to discuss different tasks and projects."
What do you like best about Slack?

Huddle, it's fast and easy to just call the colleagues, no need to add personal social media or create Teams/Zoom meeting links.

What do you dislike about Slack?

Pictures in the conversation can not be replied on threads, so sometimes will be hard to select certain images. Will be very nice to add .gif function, to create more reaction within the company.

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

Communicate with colleagues who's out of the country or working remotely, it's easy to text or call.

"Primary Communication Platform"
What do you like best about Slack?

Very easy tool to use, and the functionality and ease of integration with other platforms is amazing.

What do you dislike about Slack?

I think like all communication platforms, it can become a bit messy with numerous channels, and lots of information being shared. This may be counterproductive.

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

Easy communication, quick messaging option, use it for internal phone calls or huddles and so much more.

"Centralized and effective communication"
What do you like best about Slack?

What I like the most is the fact that it allows me to have both private and individual conversations, while at the same time, we have various channels where we can communicate as a team effectively and clearly.

What do you dislike about Slack?

The point that leaves something to be desired, in my opinion, is that sometimes the user experience gets a bit overwhelmed with the amount of messages, notifications, and events that happen in the Slack environment.

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

Being the primary point of contact for my company currently, within our environment, we have channels for the entire company, channels for inter-team communication, channels to receive notifications and stay updated on our product's status, we receive customer feedback, and in addition to that, we get daily notifications from our agenda.

"Slack Review"
What do you like best about Slack?

Communication made easy. People from the organization can leave comments and status that helps us to determine what tasks were they on or their schedule. Created channels helps with faster communication via large size of receipients and pinned notes can be done too, topics and description can also be placed which is helpful to the users since they can differentiate on where they should be sending their message.

What do you dislike about Slack?

None. Slack helps us with daily tasks and easy communication. Highly recommended.

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

Communication can be challenging. Slack helps us determine the correct channels to reach out to and can easily check the status of the person we are trying to communicate from. Mentions between conversation can be easily seen that helps us respond timely

"best application for corporate interactions"
What do you like best about Slack?

The real-time messaging feature is a game-changer. Communication is instant, and the ability to create different channels for specific projects or topics ensures that discussions remain organized and accessible.

What do you dislike about Slack?

one common complaint is the potential for notification overload, especially in larger teams or busy channels. Users may find it challenging to manage and customize notifications effectively, leading to distraction and reduced focus.

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

easy to navigate. Setting up channels, direct messages, and integrations is a breeze, making it a user-friendly platform for both new and experienced users.

"Best communication platform for any team size"
What do you like best about Slack?

The most helpful thing I find about Slack is its integrations with a lot of other platforms. In my company, we had multiple integrations with slack, like asana, donut, small improvements, and what not. It makes it very very easy to track the notifications via slack as it makes the communication very quick when you're working.

What do you dislike about Slack?

I don't find any major downsides for slack but I do believe there's some room of improvement for the notifications part. Sometimes I do miss some texts on the channel because of too many texts and slack doesn't give continuous notifications.

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

We use slack for quick communications within the teams, or with individual teammates. Slack here helps a lot when there's a need to communicate urgent information to a larger audience with the help of channels, literally in seconds, no matter in what time zone the employees are.

"Streamlining Communication and Collaboration"
What do you like best about Slack?

Having used Slack in my workplace, I've witnessed its impact on team interaction and collaboration. Despite working remotely, our entire company is connected on Slack. It's like a digital hub where we can chat, share files, and keep up with what's going on.

What do you dislike about Slack?

It takes a lot to track all the different channels and conversations now that I'm part of almost all channels.

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

We've made separate groups for each project or topic, which helps keep everything neat and organized. Overall, Slack has really improved how we talk and collaborate as a team. Every team is on the same page.
