"Intuitive Team Chat and Strong Integrations, but macOS App Slows Down and Pricing Adds Up"
3.5/5
What do you like best about Slack?

The user interface is very intuitive, and it’s probably the easiest team chat app to use. The integrations with external services are genuinely helpful, and the ecosystem feels mature enough that you can find pretty much everything you need.

Most of the issues I’ve run into are with the macOS native app. It’s quite slow and not very reliable: I often have to restart it, and sometimes thread replies don’t show up at all. Because of that, I mostly stick to the web version, which works much better for me.

Another downside is the pricing. It gets very expensive if you have a big team. Review collected by and hosted on G2.com.

What do you dislike about Slack?

The biggest downside is the pricing. It is good software, but there are cheaper alternatives out there Review collected by and hosted on G2.com.

"Slack Streamlines Team Communication with Intuitive Integrations and Brilliant AI Summaries"
5/5
What do you like best about Slack?

Slack creates a single source of turth of communication acorss teams both internal and external teams. While it doesnt have all the tools you will need in your tech stack it typically will have a connector to that tool such as google drive, outlook, dropbox, troll, etc.... It is fairly intutitve tool and can be customized to fit your needs. I find it to be very responsive and easy to use. The cost of it i nominal when you consider the streamlined benefits of clear communication. The only difficuly I would say is that when you are handling extremely large teams the messaging and the notifications can feel a bit overwhelming at times. The ai tool, espeically the summaratization tool is brilliant and saves you hours of recap. Lastly the support while mostly auto pilot is easy to access and intutitve to handle.

"Slack Made Freelance Client Communication Easy"
5/5
What do you like best about Slack?

Slack has been a very important tool in my freelancing journey. It helps me stay connected with clients professionally and keeps communication organized. The private channels feature is one of the best parts because I can create separate workspaces for each client, making project discussions, file sharing, and updates easy to manage.

The UI/UX is clean, modern, and very beginner-friendly. Everything is easy to navigate, from messaging and notifications to file uploads and team collaboration. Even clients who are not very tech-savvy can use it comfortably.

Slack also offers excellent integrations with tools like Google Drive, Zoom, Trello, and Dropbox, which improves productivity and saves time during project management. Having everything connected in one platform makes freelancing work much smoother.

In terms of performance, Slack runs reliably and delivers messages instantly without major issues. The desktop and mobile apps both work well, allowing me to communicate with clients from anywhere.

The pricing is affordable and provides great value for freelancers and small teams. Even the free version includes many useful features, while the paid plans are reasonably priced for the productivity benefits they offer.

The onboarding experience is simple, and setting up channels or inviting clients takes only a few minutes. Customer support resources and help articles are also easy to access whenever needed.

I also like the AI and intelligence features that help improve productivity by making searches, message organization, and workflow management smarter and faster. It helps save time and makes communication more efficient during client projects.

Overall, Slack is an excellent communication and collaboration platform that has helped me manage client relationships, organize projects efficiently, and improve my freelancing workflow. Review collected by and hosted on G2.com.

What do you dislike about Slack?

I don’t have many complaints about Slack because overall it has been very useful for my freelancing work. However, sometimes I notice a small glitch in the web version where a chat section gets stuck in an infinite loading loop. It usually fixes itself after refreshing the page, but it can interrupt workflow occasionally. Other than that, my experience with Slack has been very positive.

"Slack Makes Cross-Team Communication Effortless"
4.5/5
What do you like best about Slack?

Slack has been great for our company. The biggest benefit has been how easy it makes communication between departments and across 4 different locations. We use different channels to share schedules, deliveries, launches, and product changes, and it also gives staff a simple place to ask questions. We also rely on private messaging, which feels more informal and quicker than email.

We’ve been on the free plan for roughly two years now. I can see there are plenty of perks with the paid offerings, but we haven’t needed them yet; still, they seem like they’d be a strong fit for a growing business. Over the years we’ve had zero issues, and adding or disabling staff has been a breeze. Review collected by and hosted on G2.com.

What do you dislike about Slack?

One drawback for me, as the account “owner,” is that I can’t see all channels to understand how many have been created, who is creating them, and whether there’s any overlap. I believe that kind of visibility may be included as a perk on the paid plan. In my opinion, the pricing structure starts quite high, so we can’t justify the cost right now, even though I’m sure there are many integrations and other pros with the paid plans. One other big thing I wish Slack had is autocorrect and grammar support. Review collected by and hosted on G2.com.

"Slack Makes Team Collaboration Easy and Organized"
5/5
What do you like best about Slack?

What I like best about Slack is how easy it makes communication without feeling overwhelming. It keeps conversations organized through channels, threads, and integrations, so it’s much easier to collaborate with teams, especially during projects or fast-paced work. I also like that it works well for both quick discussions and more technical collaboration without needing endless meetings or emails. Review collected by and hosted on G2.com.

What do you dislike about Slack?

One thing I dislike about Slack is that it can become distracting when there are too many channels, notifications, and constant messages coming in throughout the day. Sometimes important updates get buried in conversations, especially in larger teams. It can also feel difficult to fully disconnect from work because communication is happening all the time.

"Slack is Powerful Central Hub for Tool Integrations and Notifications"
5/5
What do you like best about Slack?

It integrates with so many tools that it’s easy to make it the central hub for communications and agent-based tooling interactions. It also works well for notification centralization, so you don’t have to keep an eye on multiple apps. You can simply pipe external notifications into Slack channels. Review collected by and hosted on G2.com.

What do you dislike about Slack?

I think they could do a better job of letting you create webhooks directly from the Slack app, rather than pushing you to the website to set everything up. It would also be helpful to have a wizard that walks you through the steps, so there’s less ambiguity and it can suggest best practices along the way. Review collected by and hosted on G2.com.

"Easy Team Communication and Efficient Collaboration with Slack"
4.5/5
What do you like best about Slack?

What I like most about Slack is how easy it makes communication and teamwork. The channels help keep conversations organized, and the search feature makes it simple to find old messages or shared files quickly. I also like the integrations with other tools because they save time and make work more efficient. Overall, Slack helps teams collaborate faster and stay connected in a professional but simple way. Review collected by and hosted on G2.com.

What do you dislike about Slack?

One downside of Slack is that it can become overwhelming when there are too many channels, messages, and notifications. Important updates can sometimes get buried in busy conversations. I also think the free version has limitations, especially with message history and storage. In addition, constant notifications can be distracting and reduce productivity if not managed properly.

"Streamlined Team Collaboration, Few Hiccups"
4.5/5
What do you like best about Slack?

I like that Slack makes communication and collaboration easy and feels organized with channels, direct messages, and quick updates all in one place. The channels are particularly helpful because they keep conversations focused and searchable, making it easy to find information later. Huddles are great for quick discussions when a message isn't sufficient. Slack's integration with tools like Google Drive and Claude adds convenience by keeping notifications, updates, and collaboration in one place, which is useful to avoid switching between apps. The initial setup was straightforward, and we adopted it without much difficulty thanks to its intuitive interface. Overall, Slack has improved our teamwork significantly by making communication faster, clearer, and more efficient. It has also allowed us to move away from long email threads to more organized and quicker collaboration. Review collected by and hosted on G2.com.

What do you dislike about Slack?

The main area that could be improved for me is Huddles, since sometimes the audio stops unexpectedly, which can interrupt the flow of a conversation. Aside from that, my experience with Slack has been very good, and I find it reliable for day to day communication and collaboration. Improving the stability of audio in Huddles would make an already strong tool even stronger. Review collected by and hosted on G2.com.

"Overwhelming Interface, Needs Simplification"
1.5/5
What do you like best about Slack?

I appreciate being able to follow multiple channels and the related conversations in my investor group since it seems very clear and straightforward, simple to use. The breakdown or sections for these different channels work very well, and I've been enjoying that. The ability to see a thread of messages and reply to specific comments seems common and easy to use. I like that feature because it ensures nothing gets forgotten in conversations. Review collected by and hosted on G2.com.

What do you dislike about Slack?

So my overall experience with Slack is, I would say, negative in the sense that it's all over the place. There are features and elements everywhere. Seems very complex, and I'm a tech-savvy person, but I never know exactly where on my phone I can get the latest notifications or not. I don't want a notification for everything. I don't understand when I get notified. People tag you. Sometimes they don't tag you. A message. So I never exactly know when it's for me, when it's for the community. There are some notifications I would like just for specific channels, but not everyone, and I can't easily find how to set it up. There is a huge difference between the interface on a browser versus what you get on the phone. It's very messy. It's not easy to find information. There are icons everywhere. I don't enjoy the experience at all, but it's the only option that Notion as well as the investor community proposes for this chatting. So I would rather prefer a way more lean interface, way simpler in the way to use it. Review collected by and hosted on G2.com.
