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 is a very user friendly Platform compared to the different platforms"
What do you like best about Slack?

Slack is a very user-friendly platform I am using this since the beginning of my career after using multiple platforms I feel slack is really very convenient and user-friendly as we can easily mark our status and get notifications when tagged in a group.

What do you dislike about Slack?

There are not many things I dislike about it as it's most convenient to other platforms I used but one feature I want slack to add is to increase the length/ the limit of maximum allowed characters. User interaction should be improved as well, also profile name should be editable, should not ask if we want to change our status to active every time we visit other than these there are the most feature I like when comparing with other chat platforms that make slack the most convenient platform for user who regularly use it for work purpose.

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

There are really many things I benefit from slack like adding documents directly, notifying people in the group and I can also use my self chat for storing some important notes/ documents and others for easy access and also it helps us to update our status accordingly which is really very beneficial when we are away and also helps in sharing screen and scribbling on screen needed.

"I use slack to chat internally whith my colleagues and sharing personal and secure infromation."
What do you like best about Slack?

I can able to chat with anyone with my company. Mostly I can chat with IT support team and can share my screen by huddle or by calling. And also the information is secured like no outer organization person can see those things.

What do you dislike about Slack?

It's perfecly fine. I just can delete the whole chat and another person messages in the chat. Like, I should be able to delete the conversation and can start the conversation from the start.

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

By using slack I can directly share my points or can ask my doubts with my team leader or manager by just pinging them in slack. Also I can able to call and share my screen also. One more option of adding Apps so that any notification can directly comes to me. For example I can add outlook calender so I don't miss any of m scrum meetings.

"Slack is the most integrated & easy to use tool"
What do you like best about Slack?

I like how slack is integrated with all my other tools like: SFDC, Gainsight, Surveys, Google Calendar etc. There's so much I can achieve with Slack outside of communicating with my peers, I can work on group assignments easily, create tickets and make requests. Alongside that I also make calls, start huddles and Zoom sessions from 1 tool.

What do you dislike about Slack?

I'm not sure there's anything I dislike? Apart from hell when there's an outage and I cannot use slack. I'm dependent on the tool and I even use it on my phone.

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

collaboration, project management, escalation, working across territories, working with partners in one single interface. We're all over the place so it's handy to have 1 tool that's integrated and helps us work better and faster.

"Slack is the versatile chat app that helps people stay engaged and productive"
What do you like best about Slack?

I like how slack integrates with many other apps it allows for that umbrella approach to communicating with teams without constant meetings or emails. It is quick easy and users are very upset if they lose access which is usually a huge sign of its value.

What do you dislike about Slack?

Not much I don't like about slack, maybe it would be nice if it were better integrated with Microsoft office, especially email but that is just a personal opinion, there might just be a way I have not figured out yet. Otherwise, I do not have any complaints about the software, it does what it is designed to do~

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

Communication is the biggest in my eyes. When you work for a company that is completely remote there has to be an open channel of communication and I feel Slack fills that gap and more.

"Review for SLACK!"
What do you like best about Slack?

We've started using Slack at work to monitor the apps (like: Discord) we link to with Slack. Group chats are also possible using Slack. Significant discussions can be pinned in Slack.

What do you dislike about Slack?

Although cost is a concern, a great deal of value is offered in exchange. If you're migrating to a new workspace, you won't be able to migrate your chat history from one workplace to another.

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

Slack has evolved into an immensely helpful a-synch business communication tool because of its automatic transcription of videos and audio messages. It scares me how much I prefer it to email.

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

It is very helpful in communicating & keeping things professional. I don't want to engage on WhatsApp with colleagues.

What do you dislike about Slack?

Its color is very dark, not something I am fond of.

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

Communicating over WhatsApp with colleagues is wrong & slack removed that bridge. It helps in keeping personal life separate from professional life.

"Great tool for easy communication with team"
What do you like best about Slack?

I like the instant messaging feature and the fact that in syncs on multiple devices and the integrations with other apps like Google Drive and others.

What do you dislike about Slack?

That you have to install apps to integrate. It should be automatically synced.

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

Team communication within a fully remote company. I save time and money as an employee by working from home. I and the team are more productive using Slack.

"Does everything you could possibly need - and then some"
What do you like best about Slack?

The bots for calendaring events and reminding you when they are upcoming. There is also a place to see all calendared events so you can see what you have on the agenda at any given time. You can also customize notifications.

What do you dislike about Slack?

There is a bit of a learning curve when you first get started, there are a lot of features, and if you are just using it to chat between co-workers then it's not being used effectively and it seems like too much of a system.

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

We are able to coordinate between many departments all in one place, plan events, meetings, and meet within the app. We can have bots make our job a little bit easier and schedule for us.
