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.

"A gateway to the best professional setup"
What do you like best about Slack?

Slack has channels in it which make it easy to navigate. Through these channels you can limit conversations to places where they are meant to be. Members can be added or removed based on priority. There are also reactions/stickers which make it fun.

What do you dislike about Slack?

Although Slack is easy to use it does not have read receipts so a message can be sent and we wouldn't know if it has been read or not. However this problem can be solved by reaction emojis.

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

Slack is solving the issue of separating private space from professional work space. With integrations, better file/text searching options slack makes it easy to find documents/texts etc and also keep work related things restricted to professional channels.

It helped my boss and I stay on the same page and working together on things without having to constantly check in with one another, or be following up all of the time.

I didn't really dislike anything in particular. We were not able to use it to its fullest capacity because our organization didn't allow the use wide spread.

Slack helped us to stay up to date on what part of a project the other people were on, and how they were progressing. We also could easily communicate and share documents, etc.

"Slack makes life easy, but Slack becomes your life"
What do you like best about Slack?

I like that you are easily able to ask a question to a coworker without walking to them and disturbing them. I like all the not automated features and reacting with emojis

What do you dislike about Slack?

I dislike that Slack gives coworkers the liberty to contact you at any hour of the day. It's not always great with communicating throughout time zones.

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

We are using slack for daily updates on our department to-do lists, which causes less meetings.

"Makes Company Instant Messaging Easy"
What do you like best about Slack?

I think my favorite part about slack is its ability to handle a diverse set of content, from voice recordings, text, code, Gifs (for fun) and numerous different types of attachment with small representations.

What do you dislike about Slack?

I think what I like the least about Slack is that it can all seem a little much and confusing. There are a lot of buttons and things going on though, overall it can be neat once you learn to use them.

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

Slack is helping me communicate with team members quickly and effectively. It is allowing us to share messages with one another easily and send content to one another without a problem.

"Help Communication Tool"

What do you dislike about Slack?

I wish I could alter notifications more, but that is being picky. I have enjoyed using Slack!

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

Communicating in between meetings as a remote-first company. It has also helped build culture as it's been a place for folks to stay in touch throughout the day.

"Slack is the best intercompany organizational platform"
What do you like best about Slack?

Communicating with teammates, creating different channels for different initiatives and intercompany planning. Also great to run projects with external teams if available.

What do you dislike about Slack?

There aren't many dislikes. Sometimes too many notifications can be distracting but you can customize all your notifications so you can prioritize important must read items vs. can read later items.

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

Intercompany communication and connectivity. Remote workspaces make it tough to stay connected, but slack is a more user friendly and much faster alternative than emails.
