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.

"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!
