Pros:

The giphy integration is the perfect way to get folks engaged. I love the search function and the auto-response feature the best.

Cons:

I get lost on some of the channels - there are a lot of channels with different teams. I find that I get confused with which channel is for what.

Slacktopia: Simplify Your Interaction

5.0 10 months ago

Comments: Overall, I've had nothing but great experiences with Slack. It's a really helpful platform for project management, teamwork, and communication. It is an invaluable tool for increasing productivity and encouraging teamwork because of its user-friendly interface, wide range of customisation options, and smooth connection with other programmes. But sometimes it might be difficult to handle notifications and information overload; it takes careful planning and moderation. Slack is still a vital tool for contemporary workplaces in spite of this.

Pros:

The best thing about Slack, in my opinion, is how easily it integrates with different communication channels and has an intuitive UI that makes it simple to share files, remain in touch with coworkers, and work efficiently in real-time. Its extensive app integrations and customisation possibilities also improve productivity and simplify workflows.

Cons:

Slack's potential for information overload, especially with regard to channels and notifications, is a disadvantage that can occasionally result in decreased focus and distractions. Additionally, without appropriate planning and communication channel control, managing big teams or complicated projects can become difficult.

Meh. Its average.

3.0 2 months ago New

Comments: Meh. It's average. It's not the worst, but it doesn’t stand out as the best. Maybe my needs haven’t caused me to dig into its full range of capabilities, but I haven’t found a single killer feature.

Pros:

Decent group chat software. Easy enough to figure out the basics.

Cons:

If you want to go past the basics or use this for more than a simple chat system, you can. But in my opinion it’s complicated and not intuitive.

Slack review by an Amazonian

5.0 4 months ago

Comments: My overall experience with Slack is very positive.

Pros:

I like that it is easy to edit a message. I like the ease of posting anonymously. I also love that there are loads of groups. Finding a link within chat is also good, so I would say overall their search functionality is good.

Cons:

The vast number of emoticons can make it look less business-like at times.

Slack is great for work groups

4.0 2 months ago New

Comments: I’ve used Slack for years now and I love the ease of use. I love how I can quickly brainstorm something for the group and leave it in the chat or schedule it to be delivered when everyone is available.

Pros:

I love that it’s fairly easy to use for beginners once you get the hang of it. I love that you can add photos, links, attachments, etc to messages and groups within Slack and you can also have multiple accounts for different businesses, work, school, and clients. I love that it has an app so that I am able to use it on the go from my phone, tablet, or laptop. I love that you can silence or stop notifications and getting messages at a certain time until the next day. It helps you keep work and home separate as well because you aren’t constantly getting notifications after hours if you use it for work.

Cons:

I don’t really have any issues that I can complain about right now. Everything I needed Slack for it worked great.

It doesnt get better than Slack

5.0 2 months ago New

Comments: I love it - it works so well for me and is a great way to communicate with my colleagues. I love all of the features and am constantly amazed with all the things it can do - automation is definitely a huge drawcard for me!

A fundamental tool for collaboration within the workplace

5.0 3 months ago

Comments: Slack is the main tool in my role. In a fully remote position, the entire workday happens on slack, which is a reliable tool to manage conversation within a team, and across different teams. The integration with external tools (eg Knowledge Management tool) that allows to surface them within the Slack interface facilitates conversations since it allows to stay within the tool.

Pros:

- Integration with other tools - Conversation management (threading, scheduling) - emoji customization to match company culture

Cons:

- difficult to manage multiple threads without popping them out

Great Product, Highly Recommend for Workplaces

5.0 4 months ago

Comments: Overall Slack offers a great user-friendly program. It offers a lot of customization and organization tools such as sorting your channels, setting reminders, making lists, and many more! It is a great program to use especially in a WFH environment to help keep you updated and in touch with everything!

Pros:

User-friendly in the app and web browser. I love the customization features and the ability to sort out channels within your screen for a more organized experience.

Cons:

Slack is a great program. I miss the split screen feature where you could have 2 channels/chats open on the same page at the same time. Please bring it back!

Strong points but staying behind supporting fun/direct interactions

4.0 4 months ago

Comments: It is reliable, consistent but not so "fun", the company I worked for has started to use Gather to make our home office interactions feel more personal. As you need to move to another person's desk and interact with them or see if they are talking to someone else. In slack you can see they are in a huddle or busy with a Google Meet but when off you can chat with them but need to wait for that person to read you and answer instead of just being able to talk to to them without "ringing".

Pros:

I can set up channels that will remain fixed instead of chats that get lost in between all the chats. I like that I can star chats and channels to reach them easily.

Cons:

When I start a huddle, the call window gets lost or is small, and when I make it wider, it doesn't pop up immediately in the front and I have to look for it between all my open windows. Also, I didn't get the lists feature , I have no idea what is the value of it for me as a product manager that uses Jira.

This is an essential service when proceeding with the project.

5.0 5 months ago

Comments: When working on a project, it is very important how to collaborate with the participating members. Slack is very good as a service that we create together, such as quick conversation and data sharing.

Pros:

Create projects, create channels, and easily invite members. You can have real-time conversations with the invited members, such as 1:1 conversations and group conversations, and discussions and discussions on various topics within the channel. Also, within the same project, a separate channel for each task can be created and proceeded, so the project can be operated in various forms. And Slack is very light, providing a pleasant service environment.

Cons:

I am using only the necessary functions of the slack, so there is no disadvantage yet.

Slack is a must have for your development team

5.0 2 months ago New

Comments: My favorite instant messaging tool for the workplace, especially since I am on a development team. The integrations also create a single place to get updates on all of the work going on.

Pros:

Easy to use, lots of plug ins and integrations. Developers love this app and it allows you to create channels as well as small adhoc groups to keep people up to date and have quick conversations. Huddles are also very convenient for a quick oral conversation. We have integrated it with Atlassian to keep people up to date on tickets and changes in status. We also have channels with external partners to make communication with them even easier.

Cons:

Sometime the number of channels and direct messages you have available at any time can be overwhelming. You can remove yourself from channels and delete direct messages but often there are a lot that you want to keep up with.

Transforming Team Collaboration with Ease

4.0 3 weeks ago New

Comments: My overall experience with Slack has been excellent. It has transformed the way our team communicates, allowing us to stay connected and productive even when working remotely. The platform fosters a sense of collaboration and ensures that everyone stays updated. While there are minor drawbacks, such as notification management and storage limitations, the benefits far outweigh them. I would highly recommend Slack to any team looking for an efficient communication tool.

Pros:

What I like most about Slack is its intuitive interface and the seamless integration with other tools we use daily, like Google Drive and Zoom. The ability to organize conversations into channels makes team collaboration efficient, and features like reminders and scheduled messages help keep everything on track. The search functionality is a lifesaver when looking for past discussions or shared files.

Cons:

What I like least about Slack is the notification system. It can become overwhelming, especially in large teams with multiple active channels. Although there are settings to mute channels or customize notifications, it still requires constant adjustment to avoid distractions. Additionally, the free plan has limited message storage, which can be frustrating when trying to access older conversations.
