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.

"Like that 'blue' app... but for work"
What do you like best about Slack?

I love that it gives me the ability to contact others within my organization quickly even though I work from home. Sometimes a simple message works better and quicker than a phone call and especially faster than an email!`

What do you dislike about Slack?

I really don't have any misgivings in regard to this app. I wish more companies, organizations, and social clubs used this as a quick means of communication. I'm actually pleased with this app!

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

If there's a problem with Zoom, I'll use the video or call feature in slack. This app enables me to contact others within my company in a fast and efficient manner

"Slack is super!"
What do you like best about Slack?

I love the search feature. I love how you can search certain channels for keywords and tell the search that you are looking for a message sent by a specific person.

What do you dislike about Slack?

I honestly can't think of anything I dislike about it right now. It works great. Sometimes certain channels take a bit to load, but thats only when I haven't accessed that channel for a bit or if there are a ton of members.

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

It solves the problem of trying to remain connected to your coworkers in a fully remote world. It gives my team a virtual room that makes us feel more like a collective and collaborative team.

"One of the fastest chat tool that I have ever used!"
What do you like best about Slack?

The tool loads really fast Fast. The quick huddle reduce the use of meeting links. Canvas to share and take notes. Custom smilies, workflow automation, customize apps, group channels.

What do you dislike about Slack?

Nothing Much. If they have more features on Canvas like quip have, they can surely replace quip for most of the organisation. There should be a warning on the tool when you huddle to a channel.

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

It gives the quickest way to connect. Provides a mobile app. Huddles solved the problems quick connects. The canvas makes it easy to share documents with team. The best part is creating custom smileys with your own face.

Conversation among international colleagues. Through slsck i am able to draw a line between personal messaging and work messaging and the channels are working very well.

"Slack is great at connecting people quickly"
What do you like best about Slack?

When I use Slack, I find that I get a faster response than email or phone. It's great for quick questions, something that needs immediate resolve. Slack also allows for more personality in conversation.

What do you dislike about Slack?

When you have a lot of channels and one to one messages, it can be a lot to manage the amount of communication and lose track of conversations or action items.

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

Slack solves for a quick messaging system that connects internal users across the company. The Slack Huddles are a fast way to connect without having to schedule meetings.

"Accelerate your collaboration"
What do you like best about Slack?

I've used many different messenger communication platforms, but slack takes the cake! Not only did it just release an easy new interface to find and catch up on threads and mentions, but it allows you to search for past messages with filters, add polls, and keep things light with gifs and emojis.

What do you dislike about Slack?

Filtering by people you just chatted with, but are maybe not in a thread or individual conversation, and is already read.

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

Connecting at a faster pace with team members and starting on the same page.

"Head and Shoulders Above Alternatives"
What do you like best about Slack?

Slack is fast, clean, and does exactly what I need it to do. It has no bloat, and I can connect it to seemingly anything. I've used Teams, Skype, and other alternatives - they simply don't stack up.

What do you dislike about Slack?

The mobile app is occasionally moody about setting up push notifications for DMs. It would be ideal if there was an easier way to either report this or access a bug report.

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

I work with a VERY large team with many, many granular departments. I can easily mute threads that don't concern me, and hide my team away from teams that don't need to interface with them.
