The direction is the important point: chat volume is still climbing, but it’s not immediately clear whether it’s led to higher productivity or better work outcomes when you consider the cost of constant distraction. Which means you need to take a closer look at the messaging tools you use, including Slack, and decide how and when you should be using them. Let’s go.<\/p>\n\n\n\n
Short answer.<\/strong> Slack is very good at moving information between people, but poor at holding on to or retrieving that information later and turning it into actual work. Adopt it as your communication layer, and it earns its price. But don’t expect it to double up as your system of record.<\/p>\n\n\n Our editorial team follows a transparent, research-backed, and vendor-neutral process, so you can trust that our recommendations are based on real product value.<\/p>\n\n\n\n Here’s a detailed rundown of how we review software at ClickUp<\/a>.<\/p>\n\n\n<\/div>\n\n\n Slack is a workplace messaging platform organized around channels and threaded conversations. Instead of sending emails to a distribution list, you post in a channel grouped by team, project, or topic, and replies stay in threads so side discussions don’t bury the main one.<\/p>\n\n\n\n Beyond messaging, Slack includes huddles for quick audio and video calls, canvases for lightweight documents, and lists for task tracking. Workflow Builder lets you automate recurring work without code, while Slack Connect lets you work with external orgs (clients, vendors, agencies) in shared channels. The platform’s app directory holds more than 2,600 integrations to run connected workflows.<\/p>\n\n\n\n On paper, it covers messaging, calls, docs, tasks, and automation. Whether that range is a strength or a problem is what the rest of this piece is about.<\/p>\n\n\n Slack’s core strengths are fast, reliable search, open channels, deep integrations, fair billing on inactive users, and genuinely current AI.<\/p>\n\n\n\n Reviewers volunteer this one without being asked. One Reddit commenter<\/a> said Slack’s search alone justifies the cost, and rated it above both Google Drive and Teams. On a paid plan, every message, file, and thread is retained and searchable. For a team that mostly makes decisions via message threads, that turns chat into an archive.<\/p>\n\n\n\n Anyone can find a Slack channel, join it, ask a question, and leave. One sysadmin managing roughly 10,000 employees<\/a> explained the difference. In Teams, for example, you have to build a team, add everyone to it, and hope the permissions land correctly. Slack skips right over this complexity. That’s one of the reasons why Slack spreads inside companies without a rollout plan.<\/p>\n\n\n\n Jira, Drive, Salesforce, and GitHub all post into Slack channels, so teams get updates right away. The reviewers who like Slack most<\/a> are the ones who wired it into their other tools. Workflow Builder handles the routine parts without code, and you can automate recurring Slack messages<\/a> like standups or release notes.<\/p>\n\n\n Slack’s Fair Billing Policy<\/a> charges only for members who take an action within a 28-day period, and credits you back prorated for people who go inactive. Most per-seat software bills you whether anyone sits in the seat. Slack does not. That softens the cost complaint below.<\/p>\n\n\n\n On AI, Slack has shipped more than most chat tools, but what you get depends on your plan. Pro includes conversation summaries and huddle notes. Business+ adds AI search, daily recaps, translations, file summaries, and Slackbot as a personal AI agent. Enterprise search, which reaches into connected apps and databases, is Enterprise+ only.<\/p>\n\n\n Read More: <\/strong>Our walkthrough of how to use Slack AI<\/a> covers the details and hands-on use cases.<\/p>\n\n\n<\/div>\n\n\n Slack’s most-cited disadvantages are notification overload, per-seat cost growth, weak meetings and recording, a 90-day free-plan history limit, and manual timezone handling.<\/p>\n\n\n\n Nothing else comes close in the review data. Reviewers describe alerts<\/a> getting out of hand quickly, busy channels producing too much noise during release periods, and important information getting buried in active conversations. These are direct consequences of the open-channel design that appears in the pros above. Organizing Slack channels<\/a> and agreeing on Slack etiquette<\/a> will fix most of it. <\/p>\n\n\n\n Price is the single most upvoted complaint across the Reddit thread asking what people dislike<\/a>. One reviewer simply called it out as pricey. Another called it expensive and hard to leave once you are hooked, then admitted the return still came out positive every time they ran the numbers.<\/p>\n\n\n\n Reviewers describe Slack as a chat tool that also does calls, not a meetings tool. One said the meetings are slow with a clunky interface<\/a>, and that the focus is clearly on chat. Recording is a common gap<\/a>. One Reddit commenter said they dislike using huddles more than they dislike Teams meetings, which is a low bar to miss. If you want more detail, we compare Slack huddles and calls<\/a> separately, too.<\/p>\n\n\n Free workspaces keep 90 days of message history, allow 10 apps, and limit huddles and external messaging to one-to-one. Slack also deletes free workspace data after a year. For a team that adopted Slack casually and now relies on it, that ceiling arrives as an unpleasant surprise rather than a planned upgrade.<\/p>\n\n\n\n Top-voted on the thread <\/a>asking what people dislike was not about price or noise. It’s much more basic. Writing “4 pm” does not translate into each reader’s local time, the way it does in some other tools. It may seem like a small thing, but critical every day for distributed teams.<\/p>\n\n\n\n Line up Slack’s pros and cons and you’ll see the same feature on both sides, almost every time.<\/p>\n\n\n\nHow we review software at ClickUp<\/h4>\n\n\n\n
