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.

"Chat like a pro!"
What do you like best about Slack?

Connecting with team members across the globe.

What do you dislike about Slack?

Once the group is created, you cannot add a member to a group chat. We have to make another group altogether.

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

Connecting with peers across the globe, changing/updating status. Super easy, just like Whatsapp, we can depend on it for security purposes. Important communication happens related to the work.

Slack helps to organize conversations in a way that feels more natural and like a chat rather than stop and go communications via email.

Slack notifications and navigation options can be a bit confusing for someone that is accustomed to email. It would be nice to simplify the user interface.

"Most Remarkable Communication Tool, Best-in-class Project Capabilities and Tasks."
What do you like best about Slack?

Slack is the ultimate most used, trusted and powerful communication platform that any organisation can dream of having. Intuitive UI easy the navigate and use for even the starters. It's also highly customisable to meet all users needs. When it comes to pricing this tool is very fair,any organisation size can use this tool because of the cost effectiveness. I like that it's full featured with features like easy to make video calls, file sharing, adding bots to do the manual tasks which is a brilliant added advantage. I also like how flexible it can be supported by Android, Web, iOS, Linux, and finally Windows. Overall is a recommended tool that has really saved lots of my time while communicating with my remote team on important projects and tasks and hence saves lots of time and money.

What do you dislike about Slack?

It's a perfect tool for everyone best fit even the small teams, it's an easy to start using tool with a very friendly User Interface. I also like the second to none support team which is very proactive and user-friendly. Though the mobile app needs some improvements and I wouldn't mind if they keep on adding new features to make it most standout communication tool there is.

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

Slack has really been a phenomenal tool that has greatly saved us time and money especially during COVID pandemic where we had travel restrictions, it was easy to conduct our business as usual through communication, video conferencing, live chats and messaging to our clients, customers and employees. I like how this tool enables my team to submit reports quickly and easily. File sharing was so smooth and video conferencing is great. Slack bots helps us with reminders, tasks and scheduling projects which is a great tool.

The support team can be slow on responding to my cases. I wish to be more responsive and helpful in all directions. I hate it when it doesn't offer any project management feature which is very important aspect of every messaging tool.

Slack makes information proficient and puts together communication into various channels. It also helpful in that records are saved and filed for simple access. Overall I really enjoying slack.

"Revolutionary team communication Platform. Easy to Build a Community."
What do you like best about Slack?

It's easy starting from managing, setting up, and using this tool. I like the audio and video quality as well as screen sharing function which is intuitive and very much of high quality. As a Team Lead Slacks helps me monitor everyone and managing everything effectively. It has boosted our team productivity and communication over the few years we've been using it. The ability to create private channels within a workspace helps me to build a community. This tool is trusted by millions of users as the most iconic messaging app. Been easy to customize it according to my organisation needs. It's also cost effective and no extra cost charges.

What do you dislike about Slack?

Often if a notification is received on one device (i.e laptop) it will not always push to another device like phone. I hate I am not able to customize this tool Design of my channel or change the background colour.

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

We use Slack for quick and efficient communication across teams and clients. Also I use it frequently for managing access to my Google Drive, for managing cross-team projects through Google Drive also for tracking Jira Tucker and updates. Also I use this tool for teams meetings, sharing files and sensitive information. Sharing screen when required is also an added advantage. It has greatly improved collaboration and teamwork among my teammates.

"Slack is better than any workplace messenger I've used"
What do you like best about Slack?

Assigning multiple channels, how fast it is compared to teams, etc

What do you dislike about Slack?

Sometimes the notifications you get after integrating an app are annoying... you can always turn them off but I'm unaware of a setting to "turn off notifications for all future integrated apps" or something like that. Can't say I looked very hard though :)

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

Being able to communicate with other companies easily

"Slack is my favorite"
What do you like best about Slack?

I love all of the customizable aspects of Slack; the color theme, channel groups, ability to upload your own emojis, and the many available Slackbot integrations!

What do you dislike about Slack?

Sometimes it randomly makes my Windows explorer process freeze up, which I only know because things go back to normal once I force quit Slack. It's a rare occurrence, but has happened more than once.

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

Slack makes communicating with my team and other teams across my company quick, simple, and fun. I even use it to keep in touch with old coworkers. I'd prefer Slack communication over an email every single time.

"Slack - The sluggish power in today's technology"
What do you like best about Slack?

Messaging and tagging a person is super simple and complicated. We can set up calls and integrate them with our day-to-day tools used for projects. Even you can connect with people outside your organisation. Create a group of people and have a private chat. I have integrate Wrike with slack and it is super helpful.

What do you dislike about Slack?

I don't think there are anything downsides to using slack. Even people using slack will enjoy the background colour change according to time. Still, the team can think of something better to keep the competition away.

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

Lots of business problems are being solved, like having an urgent call or screen sharing. Integrate with your project management tool and get notified. Even integrate Google meet.

"Excellent for Small Teams, Intuitive Tool For Live Updates, Chats and Communications."
What do you like best about Slack?

I like the non complex user friendly features that are so much easy to use. I like how it boost our communication with my teammates and clients while receiving real-time messages through chats and calls which has been so fundamentals and adding to my organisation growth.

During video conferencing sometimes it keeps on freezing while I am using a mobile app I don't know if I am the only one with this bad experience. I hope this will be sorted out fast. Great support which is very user-friendly and robust.

It's absolutely the best tool for remote teams working remotely as it has been providing us with different channels public and private to makes or share our projects easily. It's been easy to manage many projects at a go while saving time and money. Enhances collaboration and communication across all our departments.

"SLACK REVIEW"
What do you like best about Slack?

1. Huddle feature which enables instant calling without meeting link. Also shows indication that user in on call. 2. Notification show / hide preview (This helps us to hide the message that appears in notification bar). 3. Update your status accordingly. 4. Instantly receives notification / message in phone as per our configuration. 5. You can send messages to yourself.

What do you dislike about Slack?

Sometimes the huddle call goes buggy. For a moment it will say slow internet connection and again it will get better. Sometimes for no reason it gets logged out. (A bit irritating)

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

To discuss quick things, there is not need to create a meeting link / room. You can instantly join any meeting (almost all required features are supported) and the status of user is reflected. This saves time.
