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.

"My slack review."
What do you like best about Slack?

Slack has many features that many people should like, it's collaborative features make work easier for us. Like sending draft messages and video recording with threads are good features. It is really easy to use and it's UI is also great. On pro plans we can integrate it with other apps too.

What do you dislike about Slack?

I don't dislike anything about Slack. It's doing well for almost everyone. I think should improve it's huddle features, like Google Meet looks better than huddle regarding live video rendering with internet speed.

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

For my small startup I am using Slack to do collaboration with my mate. It helps me to do it in a right way with instant messaging, message drafts, video messages and live huddles.

"Slack its so fetch!"
What do you like best about Slack?

This is the first time I use Slack, what I like the most is how easy i can create chanels and temporal groups to communicate for specific reasons. Making so much easier the colaboration between me and my peers. I can create automatizations for requests, integrations to send key information to specific users when our clients for example answer a CSAT survey. Pin important messages so I don't waste time looking for it. I can even send myself messages, put reminders and schedule future messages. As a Project Manager, Slack is my #1 tool, I use it all the time.

What do you dislike about Slack?

The workflows at the beginning were difficult to create, but after a couple of readings and excersises, everything went well.

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

Before slack we used MS Teams, and the management was so bad.

"Discord for Office Work"
What do you like best about Slack?

Slack is a very comfortable application, which allows the whole office to communicate quickly and easily. It has many integrations, making it even more useful since integrating sites like Monday.com or Google Calendar into Slack is a very nice thing to have. I use Slack every day to communicate with my colleagues at work. Having different channels for different topics makes navigation through information very easy. Overall, it makes communication between different rooms and even countries much easier to discuss work-related matters.

What do you dislike about Slack?

I cannot think of anything negative about Slack. It is a great tool for making office communication easier and more comfortable for co-workers. I can only say the pricing, which can be a bit too expensive for some.

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

Being able to chat instantly to co-workers who are working in separate offices, rooms or even countries is a game-changer. Also, Slack lets you create different channels, meaning information is not lost and you do not have to scroll infinitely through unnecessary messages. It is a very comfortable tool for office work.

"Really Enjoy the UI and Options for personalization"
What do you like best about Slack?

I enjoy the feel of Slack. I think they have done a good job in creating a UI I can look at all day and personalize. Recent changes include a more sleek look and condensed view of important channels and conversations. The huddle option makes phone and video calls super easy. I use it everyday and can access it from my phone, work laptop or other device - whihc is essential while working from home.

What do you dislike about Slack?

Sometimes I can'tmake notifications go away in the activity tab, even though I have seen all the content.

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

It's an easy way to keep in touch with anyone in my organization. it even offers an option to message people outside of my organization - which I have not used yet. I also like that I can communicate more personally with the use of gifs, emoticons, and personalized emoticons. Super fun!

"It's almost everything"
What do you like best about Slack?

- Easy to use on a daily basis - Commands reminders and archive any post you want - Channel creation, chats and invitations are smooth to do - Calls, video sharing, voice notes are all improved and easy to use on the go - Integrations are amazing and easy to implement. we use Pendo, google, Gong, Chours and Jira. the possibilities are amazing - Plenty of customization options

What do you dislike about Slack?

- Recent UI Update is problematic. like a LOT.Mobile view is even worse with the new UI but its irrelevant here for now - Some new features are inconsistent, like notes in the top right corner. Sometimes it loads your notes, sometimes it does not - Searching. its soo detailed that it feels useless sometimes. the specific search filters that you need to type are not easy to use - Problems with message notifications with the recent UI update. like google integration chat it doesnt show up on the chat but it shows up on the activity counter

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

Communication, documentation, quick meetings, Integrations for seemles workflows are the top ones I can mention

"Slack review as user"
What do you like best about Slack?

It has notification settings to messages only and we can opt to not receive notification for reactions for the messages we can go and check in the activity if we want to see which is really helpful because the work won't be interuppted.

What do you dislike about Slack?

Sometimes when person goes offline its not reflecting immediately it will be still showing for online like 6 to 8 minutes which makes people wait unnecessarily.

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

Mainly for sending admin requests in channel.It's really helpful for that.
