Reviews of Slack

Highly effective and secure tool for team collaboration
Comments: Overall, Slack was an outstanding tool for collaboration among our team.We were confident in data security knowing that all data, both at rest, and in transit, is fully encrypted.Data security is increasingly important for all firms, and branches of government.
Pros:
During branch meetings and discussions, dozens of us were able to discuss a range of topics in real time.Also, Slack is one of the most famous collaboration tools (text, voice, video and file exchange) that runs on nearly all platforms: Windows, Mac, Android, Linux, iOS, and in an online web-based version. Brilliant!
Cons:
Occasionally, Slack would not load properly and experienced connectivity problems with video and audio. But these problems may have been a result of our overloaded server, and not a problem with Slack. The allotted storage space for users may not be enough if you have large files.
Great Platform for Internal Communication
Comments: Slack is a convenient workplace communication tool. It allows us to create different team channels where we share the details of a specific project. Slack sends real-time notifications to ensure no one misses important information. We usually use it for business communications and use other apps for personal chats and it meets our expectations.
Pros:
Slack is a versatile platform that allow convenient communication using text, audio, or video. It has an simple design which makes it easy for anyone to get started easily. Slack sends notifications quickly, ensuring you don't miss important files or communication. It is better for official communication than the regular apps we use on phones daily.
Cons:
I dislike too many emails notifying me what happened on Slack. The notifications may come in handy when you missed a lot but they could also bother you because they are rather too many. The mobile app seems too congested compared to the desktop access version.
The almight community platform.
Pros:
Slack as a community app allows me to connect with others who have similar interests, share information, and support each other.
Cons:
Nothing really, slack fits all I use it for without an exception.
Essential but requires some effort
Comments: Initially difficult but once the balls get rolling it is my favorite app to get in touch with my communities.Much better than the social media app like Facebook or TwitterThis is the true meaning of community!!!
Pros:
Very nice way to handle the thread Possible to upload files and images easilyThe multiple channels is amazing to separate groupes and discussionsThe mobile app is amazingI love the notification system
Cons:
It takes some effort to understand the mechanic of itA bit difficult to invite people form outside the companyMost people do not respect the Thread replies and that makes it difficult to follow some discussionsA bit difficult to find specific posts
Alternatives Considered: Mighty Networks and Open Social
Reasons for Switching to Slack: After airing my needs to some colleagues with more experience with these softwares and trying them for a few weeks, Slack simply stood out!I have tried to create community of practice to share tips and trick for years. Each was a failure. Using Slack allow me to BE in some communities and manage some others from a single account! Amazing product!!!
Standard chat app in IT companies
Pros:
In our company most of internal communication and support of key customers go through Slack. Slack Connect is a really great thing, especially because Slack reached network effect.
Cons:
Lack of autocompletion using AI and advanced spell checking in messages.
Alternatives Considered: Google Meet
Reasons for Switching to Slack: Threads, Slack Connect, Calls (they were pretty bad, but significantly improved), Screen sharing
