Slack
Team chat organised into channels, with huddles, docs and automation
1/3Slack is a messaging tool for teams, organised into channels by project, topic or department rather than into individual inboxes, with threads, direct messages and searchable history. Beyond chat it carries Huddles for quick audio and video calls, Clips for recorded updates, Canvas for documents and Lists for tracking work, all inside the same app. Workflow Builder automates routine tasks without code, apps connect through the Slack Marketplace, and Slack Connect extends channels to people at other companies. It is owned by Salesforce, and the AI layer reflects that: Slackbot as an assistant, AI-generated summaries, enterprise search across connected tools, and Agentforce agents running natively in Slack.

Based on what people have said
Every answer links back to the mentions it came fromHow do people use Slack for AI and automation?
Many users leverage Slack as a central hub for interacting with AI agents, which can perform tasks like summarizing threads, drafting emails, and managing coding projects through dedicated channels. Some users build custom workflows to trigger actions from external events, while others appreciate that Slack allows them to monitor multiple agents and tools in one interface.

How does Slack compare to Microsoft Teams?
Opinions are divided; some users prefer Slack for its integrations and professional feel, while others find Teams more convenient if their organization already uses the Microsoft 365 suite. Some report that migrating from Slack to Teams can result in a loss of context and broken integrations, though others find Teams' search and history features more reliable for long-term data retention.

What concerns do users have regarding privacy and data security?
Some users are concerned that Slack can read their messages and that data may be used to train machine learning models unless they opt out. There are also worries about confidential information, such as credentials or customer data, being exposed in Slack exports or through third-party integrations.

Is Slack effective for project management?
Some users find Slack useful for tracking work through channels and integrations, but others feel the platform lacks sufficient structure for project management and relies too heavily on human convention to maintain order.

What people are saying about Slack
46% neutral“an ex and I had a slack workspace and it actually ruled - so good having channels/threads etc”
“An agent produces a lot of output in its session. If it all lands in Slack, it pollutes the channel.”
“I don't know anything about the ins and outs of Slack, but with everything that's changing with AI, I'm sure they're working really hard to retain their users and also integrate better with the wider Salesforce ecosystem.”
“For the first time to drop from Slack! just earlier, even though i'm working rn for that project task! But it seems i got eliminated from slack channels!”
“they make enterprise level software, there is a TON of moving peices. Security alone is probably a hefty team due to who uses Slack.”
“At least 250 of them are specifically there building the upcoming slack battlepass and virtual currency cosmetics systems”
“When Docusign needs 6000 ppl, slack can have 2000”
“Slack search engine must be insane”
“not really, slack can be used like discord as they have free tires and even paid ones are fine if you don't have a server with too many people”
“they're talking about Slack though.”
“Spot on, I hadn’t actually looked at what Slack offers in terms of risk and governance. https://slack.com/trust/security”
“Slack's 2000+ employees might seem excessive, but it makes more sense when you break it down. You've got engineering and product teams working on constant updates and new features.”
““How come slack has thousands of employees?””
“I send probably hundreds of Slack messages a day. I don’t use OF but the messaging usually costs money.”
“OF has up to 5x more monthly users than Slack, based to publicly available data. Some chunk of them doesn't message at all, some portions are going to be heavy chatters, especially creators probably send an order of magnitude more messages than the heaviest Slack users.”
“You just described slack lol”
“You think slack is easy?”
“"but I vibe-code my own slack last weekend" /s”
“Compare this with Slack.”
“You cant compare Slack to telegram, Slack is for enterprise team and therefore needs premium support which is super fast and also can have a lot of legal issues, Telegram on the other hand is an anon chat platform for individuals who rarely needs priority support...”
“Slack is running 24/7 global infrastructure, enterprise security & compliance, massive customer support, sales teams selling to Fortune 500s, constant integrations, mobile + desktop clients, and dealing with every possible edge case at scale.”
“Slack stopped being a single product company when Salesforce bought it. Most of that headcount isn't building features.”
“And I believe Slack company is nuts if they do not downscale it to around the similar number, and could disappear soon”
“Like someone said, if you wait for slack access, you’ll have this already. These chats exist in slack.”
“I get added randomly to these kinda slack channels ever so often. There’s nothing to talk about lol just people saying “what is this” and leaving. You’ll have plenty of stuff to talk about in your channels here soon trust lol”
