Room For Improvement

Atlassian Confluence struggles with integration, pricing, and user access, needing improvements in collaboration, customization, and interface efficiency.
Slack Enterprise needs better third-party integrations, user interface, notifications, video call quality, and enhanced security and customization features.
The software does not currently have any kind of AI integration.
This chart used AI to offer users the option to create it based on the data.
We can also improve the creation of channels, particularly in terms of privacy, security, flexibility, and the addition of members to newly created channels.
Configuring chats and pinning in Teams is easier, even though Slack has these features, they are not intuitive enough to engage with.
There is a need to add a call group feature to facilitate scheduling and conducting meetings within Slack.
 

Setup Cost

Atlassian Confluence pricing varies with user base and setup, with costs increasing for plugins and external access.
Enterprise users find Slack pricing reasonable but costly compared to alternatives, with paid plans preferred for security needs.
It streamlines license management and renewal processes, which can otherwise lead to complications or lapses in access.
 

Valuable Features

Atlassian Confluence excels with ease of use, collaboration tools, Jira integration, customizable templates, and cross-device accessibility.
Slack Business - Enterprise boosts productivity with seamless communication, app integration, customization, and effective collaboration tools like Slack Canvas.
This tool provides a single repository for interacting with the entire team.
In my experience, Slack is a stable product for communication, and I appreciate its automation features and integration of AI capabilities for enhancing specific functions.
We have created some error alerts and notification-related channels in the Workato recipe itself, where if we encounter any production issue errors or alerts, we receive error notifications with descriptions, error messages, and recipe names in a dedicated production error alerts Slack channel.
In managing releases via Slack channels, one major advantage over Teams is the ability to have threaded discussions, which helps in catching up on relevant discussions without the distraction of interleaved conversations.

Rabindra K Maharana - PeerSpot reviewer
Editing features improve document accessibility
There is a holiday calendar, however, I need to install an app or add something to it. The add-on feature is not readily available or well-documented. Guidance on this should be available in a forum. Recently, I used a feature in another tool—perhaps GitHub—where it helped prepare a chart. It involved listing resources, like having fifteen people in the X team, ten in the Y team, and seven in the Z team. It created a bar chart showing these numbers. This chart used AI to offer users the option to create it based on the data. It was then created on a separate page and made available.
Awais Mehmood - PeerSpot reviewer
Automation features and user-friendly interface support seamless communication
Slack is very supportive in terms of communication between my colleagues and clients. While working with the reimbursement feature, I found the automation capabilities on Slack to be incredibly useful, allowing me to automate messages for specific dates or times and even to greet someone on their birthday. I haven't specifically used the channel organization feature of Slack, as I am added to channels, but I use it with Airtable, which automates notifications to a specific Slack channel when a user fills out a form on our website. In my experience, Slack is a stable product for communication, and I appreciate its automation features and integration of AI capabilities for enhancing specific functions.
