What differentiates Slack from other similar products?
Slack is better as it resembles a “digital office.” It’s the best because it supports high-level project work as well as those “watercooler” moments that keep a team together. The difference is slack knows work isn’t all about tasks; it’s about people. It’s best because it gives us the tools to share a joke, a win or a struggle as easily as we can share a spreadsheet.
What is your favorite aspect of this product?
I love the "custom emoji" and "huddle" music it really adds so much spice to the workday.” The “canvas” is perfect for our team’s “get to know you” pages. I also find the "activity" tab very helpful to illustrate where i need to jump in, and video and audio are always clear; the "screen drawing" feature during huddles is a great way to point things out during review.
What do you dislike most about this product?
The “all unreads” feature gets very messy. I wish there was a better priority filter on this — to see my direct manager's messages before the casual chatter.
What recommendations would you give to someone considering this product?
It is the most powerful tool for a healthy positive culture along with maintaining productivity in a remote environment.
Pros
- Unique Features
- Altruistic
- Over Delivered

Cons
