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.

"So easy, love the instant communication & sharing!"
What do you like best about Slack?

Slack has been a life saver for my team of 4, who are all remote in separate locations across the US. We are able to stay in constant communication, share documents and plan around on going project better than ever before! Everything is so easy to find and you can keep your own separate notes and todo lists. Especially love the easy integration with other platforms making documents sharing better that any of the others.

What do you dislike about Slack?

There is nothing that we have ran into with Slack that we dislike... would be nice if it had a separate team calendar that could be shared within, rather than integrating to an existing platform like outlook or gmail.

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

Communication and in real-time... being able to talk with your team and get small questions resolved with little interruption to give us the ability to move our projects along in a streamlined and timely manner.

"I've been using Slack for 4 years now, & it has become an indispensable tool in my daily work life."
What do you like best about Slack?

One of the first things that struck me about Slack was its user-friendly interface. From the moment you sign in, you'll find yourself navigating effortlessly through channels and direct messages. With the ability to create channels for specific topics, projects, or teams, you can ensure that conversations stay focused and relevant. You can also send direct messages, making one-on-one communication seamless.

What do you dislike about Slack?

At times, there can be some issues with functionality, such as the Threads section failing to update as unread even after you've read all the messages within. It would be greatly appreciated if this matter could be addressed or resolved in some manner.

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

Slack effectively addresses a significant challenge in internal communication for businesses, particularly for organizations operating remotely on a global scale. It boasts a wide array of valuable features, including quick huddles for calls, seamless file sharing, instant messaging, and much more.

"Been a user for years and the first critical app to use with any business team"

The native application works really smooth and has never been down. Very reliable and have zero memory of a down period or a major bug. Close to zero bugs in entire experience.

"One of a kind app"
What do you like best about Slack?

Slack is fantastic for communication. It has a lot of neat features (audio recording, Slack call, scheduled reminders) that really makes work life that much easier. It also integrates with many many other apps like Clickup, Landbot, etc. and does it well.

What do you dislike about Slack?

Not much I can think of. A lot of the options you have come from the admin so depending on your admin, you might see more or less flexiblity around things like creating channels or adding emojis. But that's not Slack's fault :)

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

I don't know how we communicated before Slack. I rarely check my email now but Slack is a constant companion in the bottom of my screen. I find it makes me more productive and aware of my tasks.
