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.

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?

What people are saying about Slack
40% negative“Honestly the worst part is when someone updates a ticket in Jira but forgets to ping the Slack thread, so half the team keeps working off old info until someone randomly checks. That and digging through three different tools just to figure out if a PR actually passed CI or not.”
“Inbound Webhook url will be given when you make a slack app and you can post a little hitter payload into the slack api that allows a channel to be configured for what channel to pass messages down to.”
“If you have access to Slack workflows, you can connect your Salesforce org to Slack and then you can build a workflow of a Salesforce event trigger. Then you can add a slack message node to send the message to the channel.”
“Probably most of my issues could be resolved with getting used to Teams and setting changes, but I always have trouble with it and have few issues with Slack.”
“OMG I have a similar problem with old legacy Slack stuff everywhere and doesn’t do anything. Can’t for the life of me figure out how to do anything with Slack in Flow.”
“Hi there, looking to set up a basic notification in Slack when a Case is created. Can’t seem to figure out the best way to do this- I see there is a legacy app no longer supported, so I’m trying to use Service Cloud for Slack.”
“Memo: Alexandr Wang says Meta is switching from Google Chat to Slack for internal communications as Slack is the "strongest platform available today for agents" (Business Insider)”
“Yeah....exactly why we left Slack....haven't looked back. If you're interested, happy to share who we went with, don't want it to come across as an ad.”
“HipChat was bad, Slack leaned into integrations (alerts into channels), and one team could adopt it alone.”
“And people were asking for Slack instead back then too.”
“I just heard: a large company is moving from GChat (Google's Chat product) to Slack, because... Slack has much better agent operability (true)”
“The learning curve of Teams is very flat. It basically looks like Slack. It's just personal preferences that come in the way.”
“I’m building a zero-retention Zendesk-to-Slack bridge because the current ones feel bloated. Would love your brutal feedback before I finish coding it.”
“We had Slack and were going to use Mattermost as a restricted access chat option where permissions were more tightly controlled.”
“Not to defend Slack, I think it has some pretty weird defaults, but I'm sure there's some freaky folks out there who like the default config.”
“It’s funny how people are concerned with security of their messages and data, and there are some who have asked Slack to be e2e encrypted. Yet they happily would use something like slackbridge and give access to their data to a vendor with no history, no offices, no privacy agreements that hold any value, nothing.”
“honestly for desk teams slack is hard to beat, the pain is usually the frontline half who never had it and just live in a whatsapp group. that mess is why we started Pebb (i work there) - chat, shifts, the boring stuff in one app, now 100k+ teams on it.”
“Which tool you are planning to move to from Slack? A few of my clients have moved to teams and google chat because of streamlining platforms.”
“I don't think switching from Slack just to get another chat app is compelling enough to justify the migration pain. The stronger reason is if you can actually eliminate some of the separate tools around Slack at the same time.”
“But a lot of our motivations are to improve the overall experience, own our data, not be limited by Salesforce pricing and limits, etc... So more of our energies are going into that.”
“Maybe one of the worst parts about slack is how slow and crap the desktop app is these days.”
“Slack is a tools approval is a state change. Keep approval in your system with state and interface with other channels through the same adapter”
“the rest goes through one registry, one row per long running job with its state, and slack or the dashboard just read from it instead of each keeping their own copy”
“I often send fb to slack directly and they respond! If you explain how you're inconvenienced they'll sometimes factor that in for future updates.”
“We set up a slack channel for our non-profit group to communicate with. At first everyone was “wow, cool”, but within a few weeks everyone was back to using texts and emails.”
