Integrated Workspace: Slack allows you to centralize all your notifications, from sales to tech support, social media and more, into one place, making it perfect for comprehensive team communication and collaboration.

Screen Sharing Feature: During video meetings, participants can share their screens, including drawing and annotation tools, to point at specific items on the screen, enhancing communication clarity.

Slack Connect: This feature enables you to collaborate not only with your team, but also with vendors, partners, and other companies, hence allowing cross-company communication through video meetings.

Customizable and Rich-Featured Chat: Slack provides the ability to create channels for different topics, send direct messages, and use a suite of business apps and services that can be integrated to provide real-time interaction during the video meetings.

Searchable History: Slack provides a powerful search feature that allows you to find key information from past video meetings, including video content, shared files, messages, and more, that can be a valuable reference for your team.

Limited Number of Participants - Slack's free version only allows one-on-one voice and video calls. For multiple participants, you will need to upgrade to a paid version.
No Screen Sharing - The free version of Slack also does not support screen sharing during video calls, which can be a limitation for teams wanting to collaborate or present information.
Quality of Video Call - Users have reported occasional glitches and latency issues while on video calls using Slack. Compared to dedicated video calling platforms, Slack's focus is primarily business communication and organization, not solely video conferencing.
Lack of Advanced Meeting Features - Slack does not offer features such as breakout rooms, meeting scheduling, or recording that other platforms used specifically for meetings might have.
Learning Curve and Complexity - Slack has many features and tools, such as channels and bots, which can overwhelm new users trying to simply set up a video meeting. It could be less intuitive and straightforward than platforms designed primarily for video meetings.
