Had a very good experience & enjoy using slack because of the kind of customization which it provides and the support team where i stuck in implementing any bot, they became really really helpful.

Slack is a reliable communication tool that helps teams organize and connect. Channel structure and integrations are really good for day-to-day tasks. However, Ai should take place in the slack for better performance of the app.

Performance of Slack Across Market Features

Slack Likes & Dislikes

API Integration & custom bot, these are the 2 powerful tools which we as a business have leveraged by building our own custom bots which do many of the manual jobs such as collecting employee satisfaction survey, helping our employees to stay updated with the relevant information by taking from web & summarizing.

I like the music on slack when somebody leaves the huddle and letting us know you are single in the meeting. and keeps the mind peaceful.

Intuitive Huddles: The low-friction nature of huddles - now with automated AI meeting notes and multi-person sharing - makes them far superior to formal apps. Canvas Integration: Canvas has matured into a powerful way to store persistent data directly alongside a channel, reducing the need to jump out to other note taking tools. Third-party Ecosystem: Slack's app directory remains unmatched. Whether it's triggering a Jira ticket, deploying code via Github or pulling data, the integrations feel native rather than bolted on

The option I dislike the most is not having the option to have a self chat which would become handy if I wanted to text myself and keep a few things handy with me.

Slack is sitting on a goldmine of conversational data but isn't leveraging it enough. A little bit of AI goes a long way here, as features like smart Thread Summaries, Predictive Reply Suggestions, and Intelligent Message Filtering would completely transform the user experience. So overall it is a great tool with the smarter AI integration that could be exceptional.

Premium pricing and search is difficult

Intuitive Features Like Huddles Stand Out Despite Slack’s Premium Pricing Concerns

SLACK remains the gold standard for team culture and rapid-fire communications. My overall experience is that it is the most "human-centric" tool in the enterprise space.

It's easy to share knowledge, documents, create dedicated channels for topics, and it's reliable - I don't think I've ever had a down time.

Slack has been a great tool addition in terms of productivity and integration getting access to various developer tools within the flow of the work and conversation.

Director of IT

I also am curious what other organizations are doing on this front. We had an event where legal had us put an indefinite hold on all messages (email, IM, etc) and now that has just become the standard. Would like to compare what other organizations are doing and try to get us back to something that doesn't hold messages forever.
