Slack has a clean UI and is very easy to use for daily communication. Channels help organize conversations properly, and the search feature makes it easy to find old messages and files.

As an admin, user management and access control are simple to handle. Slack also supports many app integrations like Google Drive, Zoom, Jira, GitHub, and other business tools, which helps automate workflows and improve productivity.

Overall, Slack provides fast, organized, and smooth communication for teams. Review collected by and hosted on G2.com.

Some basic admin features, like better channel management and restricting who can post in channels, are not available in all plans.

To access these controls, organizations may need to upgrade to higher-tier plans, which can increase the cost. Review collected by and hosted on G2.com.

Slack has been really helpful for my freelance work because it keeps all project communication in one place. It’s straightforward to use, and I can quickly check updates, reply to messages, and stay aligned on what’s needed without missing important details.

What I like most is how much smoother it makes coordination and how much time it saves. Rather than bouncing between different apps or digging through long message threads, everything stays organized in one spot and is easy to follow. Review collected by and hosted on G2.com.

Sometimes Slack’s interface lags on my PC, which is frustrating when I’m trying to move quickly. It can slow down simple things like checking updates or switching between conversations, and that interruption breaks my flow, especially during busy projects.

Overall, Slack still works well for communication, but the occasional lag makes the experience feel less smooth than I’d like. Review collected by and hosted on G2.com.

What I like most about Slack is how it keeps team communication organized and efficient. Instead of dealing with long email chains, Slack supports real-time messaging through channels and direct messages, along with integrations with tools like GitHub, Google Drive, and Jira. This makes collaboration quicker, improves transparency across the team, and keeps project-related conversations in one searchable place. I also appreciate being able to share files, automate notifications, and connect workflows, which saves a lot of time and helps boost productivity. Review collected by and hosted on G2.com.

One thing I dislike about Slack is that it can sometimes feel overwhelming because of the constant stream of messages and notifications, especially in larger teams with lots of active channels. Important information can easily get buried in ongoing conversations, which makes it harder to keep track of updates and follow what matters most. On top of that, too many notifications can hurt focus and productivity if they aren’t managed carefully. The free version also limits message history and integrations, which can be restrictive for some teams depending on their needs. Review collected by and hosted on G2.com.

What I like most about Slack is its intuitive, lightning-fast interface and how effortlessly it supports organized communication through channels. Compared with other platform hubs, Slack feels less cluttered and does a better job of keeping conversations focused and easy to follow. Its ecosystem of integrations is also incredible—connecting apps like Jira, GitHub, or PagerDuty directly into our chats lets us manage workflows and respond to notifications without constantly switching contexts.

What I dislike most is the pricing structure, which becomes expensive as teams scale and can be difficult to justify for smaller organizations. Also, while huddled threads are useful, they can quickly get messy and hard to follow when multiple conversations are happening at the same time within a single post. On top of that, the notification settings take quite a bit of fine-tuning to keep them from becoming overwhelming during busy workdays. Review collected by and hosted on G2.com.

What I like about recent improvements in Slack is how much more intelligent and organized it has become with AI features. Slack AI helps quickly summarize long conversations, catch up on missed threads, and surface key decisions without scrolling endlessly.

I also appreciate the improved workflow automation through Workflow Builder, which reduces repetitive tasks, and the stronger integration ecosystem that connects tools like Google Drive, Salesforce, and Zoom more seamlessly. These updates make team communication faster, more searchable, and far less noisy, especially in large channels. Review collected by and hosted on G2.com.

A few honest areas where Slack could still improve:

One big opportunity is reducing information overload. Even with AI summaries and filters, large workspaces still get noisy quickly, and important decisions can get buried in long threads or active channels. Better default “signal over noise” prioritization would help.

Another area is consistency and reliability in advanced features like huddles, file handling, and integrations. Some teams still report occasional glitches or workflow friction when switching between tools or using heavier features at scale.

Slack’s growing AI layer is powerful, but it could improve in transparency and control—for example, clearer visibility into what Slack AI is summarizing or prioritizing, and more granular user control over AI-generated insights.

Finally, there’s room to improve work tracking inside conversations. Messages often turn into informal task systems, and without structure, accountability can get lost unless teams deliberately use Lists or external tools.

Overall, Slack is strong as a communication hub, but the next step is making it feel less like a stream of messages and more like a truly structured workspace Review collected by and hosted on G2.com.

I find the notification settings overwhelming at times, and searching for older messages could be faster and more intuitive. Review collected by and hosted on G2.com.

Finding search history quickly. Sending someone messages as linked threads so you don't have to repeat it. Easy setup as desktop, web and mobile. Message forwarding, gif apps integrations. Only thing this is a superb app decluttered discord and should be free because it's best. Review collected by and hosted on G2.com.

Huddles are still bad. It should be auto-integrated with google calendar as to where my time was spent from x to y time. Also, it's difficult to share screen and switch to chat in terms of UI, don't know where to click. You cna learn from Google Meet. Review collected by and hosted on G2.com.

I started using Slack for the first time in 2024 for my Deep Learning project and for team collaboration. What I like most is that the UI is user-friendly, communication is fast, and the channels are well organized. It has helped me a lot with managing team discussions, sharing files between us, and keeping updates in one place, so I don’t miss important messages like deadlines, etc. Review collected by and hosted on G2.com.

One thing I dislike about Slack is that there are too many notifications and active channels, which feels very overwhelming during my busy project work. I’ve also noticed that older messages aren’t always easy to find quickly in large group conversations. But that’s okay—overall, I like it, and the collaboration experience is very smooth.

Slack is a highly collaborative platform that has become central to how our team works together. It is easy to use, with an intuitive interface that requires very little onboarding. Since adopting Slack, our productivity has noticeably increased because conversations are organized into channels and threads, keeping discussions focused. Communication is effortless, and I especially appreciate how easy it is to exchange visual information alongside text - sharing screenshots, images, and files happens seamlessly. The huddle and call features are excellent for jumping into quick voice or video conversations without scheduling a meeting elsewhere. Review collected by and hosted on G2.com.

Honestly there is very little to dislike. If anything, notifications can sometimes get overwhelming across many active channels, and the free plan's message history limit can feel restrictive for smaller teams. But these are minor compared to the overall value Slack provides. Review collected by and hosted on G2.com.

Slack helps an entire project communicate easily through channels. Cross-functional teams can collaborate smoothly, and an organization’s employee profiles are accessible within a workspace. Bots can also be set up to automate reminders and updates. It’s also helpful for quickly looping in colleagues when there are problems with impact. The Huddle feature for calling colleagues is crisp, and I haven’t had any issues with it so far. Overall, it’s great for seamless communication and for getting in touch with SMEs, POCs, and even leadership. The main downside is that too many channels can start to feel messy and harder to manage.

Too many channels can get messy, a strong Wi-Fi is recommended while huddling, can lead to audio delays and screen share issues, hard to find an exact conversation when you need to. Review collected by and hosted on G2.com.
