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.

"Quickly connect with colleagues near or far"
What do you like best about Slack?

Slack allows you to ask quick questions that are too short for email and get replies in the moment. Slack channels are a fun way to build comradery and team culture. Slack calls are easy for short conversations or meetings. Slack integrations are very helpful such as integrations with Google Drive or Birthday bots

What do you dislike about Slack?

Sometimes Slack replaces human interactions. If I can see you across the room as you type, it might work best to just have a face to face conversation.

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

Slack helps me get what I need in the moment by chatting with collegues in real-time. No need to wait for an email reply. This allows our team to get what they need to keep things moving while still collaborating with others. This has been very benefical during COVID as all employees are working from home and we can no longer walk up to someone's desk with a question.

"Nice messaging tool that helps teams chat"
What do you like best about Slack?

It integrates nicely with many services and is widely used for support and remote work. It is also good that you can use it as an app on your computer, phone, or in the browser.

What do you dislike about Slack?

It is not always easy to manage access to channels. If you are not the admin of the whole slack system then controls of a channel may be restricted and you cannot remove the channel or make changes to it. Channels are typically either public or private and no variation between. The video chat and controls are not the best.

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

It really helps make sure people are reachable and that conversations can happen even if not everyone is able to be part of the same meeting.

"Slack is exactly what we needed!"
What do you like best about Slack?

The ability to create multiple channels and invite only needed parties is amazing.

What do you dislike about Slack?

I do not have anything I could complain about here.

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

Finding past information searchable with keywords, or better yet, "pinning" the information in a channel for quick reference later. The benefits are endless as it integrates with different software we use daily and slack is always finding ways to improve and make life easier with reminders and use.

"Great Communication Tool"
What do you like best about Slack?

Slack is very user friendly for anyone, even those who aren't tech savvy. Whether you use it for just communicating internally, or with your clients, or use their add ons to optimize performance, you will love it. You can search easily, edit your messages quickly, and get alerts based off your needs as an employee. I highly recommend this for anyone who has multiple offices, works remote, or has more than a few employees.

What do you dislike about Slack?

The only feature I feel needs improvement is the search feature within a channel or person to person message. Sometimes it just pulls in too many results and it's hard to find what you are looking for.

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

I've worked for multiple companies that have more than on office. Jumping on the phone every time you need to talk to someone across the country just isn't plausible. Slack gives you a quick and easy way to communicate regardless of location.

"Stop wondering and start Slacking"
What do you like best about Slack?

The first thing is it has a very clear interface. I love the group chat features where everyone can discuss anything in an organized manner. I also like the way it sync's with your google drive and help to send docs and file.We can connect slack with different kinds of project management tools and if we make any updates.

What do you dislike about Slack?

The only thing I don't like with Slack is the process to start a new personal chat and member search functions. it makes it a little difficult to digest when you start using Slack.

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

We are been solving a lot of team conversation problems and client conversations when we have overseas clients. The team conversation helps us to streamline the functioning of our projects. We can connect slack with different kinds of project management tools and if we make any updates on the tool everyone in the slack gets an update and this thing helps a lot when too many people are working on the same project.
