“Keeps conversations structured”

Pros

Keeping team communication organized is really simple with this. Searching for messages and sharing files with my teams takes very little effort. Creating channels for specific projects is simple and it helps keep conversations structured in real time. Sending direct messages is just as convenient which makes daily collaboration much better.

Cons

Audio and video calls rely heavily on having a stable internet connection.

“easy to navigate”

Pros

Connects with plenty of tools like Jira, Zoom and Lucidchart which makes daily work much more convenient. The interface feels user-friendly and it's simple to navigate and use.

Cons

Annoying how crowded it can get with bot messages and there have been times when notifications didn't appear properly which caused problems with my boss.

“Thoughtfully designed app”

Pros

Right from the start, it feels polished and thoughtfully designed. The UI and UX are among the best I've used and it packs in a huge range of features that most other messaging apps can't even come close to. On top of that, the number and quality of integrations are honestly incredible. It really feels like the leader in this space.

Cons

I genuinely don't have any complaints about it. There isn't anything I dislike.

“Segmented stories keep discussions separated”

Pros

Keeping conversations organized is really simple here and sharing files or attachments with the team is just as convenient. The channels are especially useful and I really enjoy how the segmented stories keep discussions neatly separated.

Cons

It still feels like a few features are missing and the full version comes at a pretty high price.

“Tricky to use”

Pros

Connecting it to other systems for push notifications is really simple.

Cons

At this point, it just feels confusing to use. Too much gets lost in the flow especially when teammates don't use it consistently. There's also no proper connection to calendars and teleconferences which becomes a real issue when you work a lot with external people.

“fast and practical”

Pros

It has been a fast, practical and really helpful tool for internal communication. It lets you create channels organize groups and coordinate activities all in one place. The fact that so many useful features are packed into a single free platform makes it even better. It also works conveniently either in a web browser or through dedicated apps for Windows android and other operating systems.

Cons

I do not have any real complaints. The only limitation is that a few features are reserved for the paid version rather than the free plan.

Being free is a big plus. It lets us stay in touch with the entire staff and we can also set up channels for specific departments, smaller groups or individual conversations.

“Enables communication across departments”

Pros

It keeps communication flowing across every department in the organization which makes it much easier for teams to stay connected and aligned.

Cons

Searching older messages could be easier. They don't always show up in chronological order so browsing through past conversations can be a little harder than it should be.

“Effective for collaboration”

Pros

It has been a really effective way to stay in touch and collaborate with remote coworkers. It keeps communication organized and makes daily conversations much more manageable when everyone is working from different places.

Cons

Would love to see a better built-in way to handle to-do items. For example, if I react with a :todo: emoji, it would be really helpful if that task automatically got added to my to-do list.

The interface is very user-friendly, simple to understand and it connects with a lot of other software really well.

“not difficult to move around”

Pros

Right from the start, the interface feels user-friendly so moving around the platform and finding the information I need doesn't take much effort. In my role as a Project Manager, I depend on it a lot for team communication, sharing updates and making sure everyone stays aligned and informed.

Cons

The nonstop flow of notifications can get distracting and a bit overwhelming at times especially when I'm trying to stay focused on my tasks.

“Lets me highlight important messages”

Pros

One of the biggest advantages for me is being able to highlight important messages, set alerts like wake-up reminders and keep key files for the whole team in the same chat space. On top of that, as an employee, I really value being able to switch my status between available, away and unavailable without ever leaving the platform.

Cons

Its weakest point or at least where it could improve, is the limitation in the free version. Searching for files and older messages is restricted especially once they are more than six months old. I don't think message search should be capped like that, it would make more sense to leave older content archived instead, except for especially important files that a team leader marks as essential.

“iOS mobile app is a plus”

Pros

Every day, I rely on it to send and receive direct messages online without any hassle. Having the iOS mobile app makes a big difference too since I can stay connected while I'm out and about and never deal with delays in sending or getting messages.

Cons

in more than four years of using it, I haven't run into even the smallest issue.
