Slack Review 2026: Still the Best Team Chat, If You Tame It
Slack replaced internal email for millions of teams. It organises conversation into channels, integrates with almost every work tool, and — used carelessly — becomes a full-time job. This review covers both sides.
Why teams choose it
Channels keep discussions findable and searchable, so institutional knowledge lives somewhere other than someone’s inbox. Threads keep side conversations from derailing a channel. Direct messages, audio and video huddles, screen sharing and clips (short recorded walkthroughs) cover most of what small teams need without a separate meeting tool.
Integrations are the moat
Slack connects to thousands of apps: Google Drive, GitHub, Jira, Notion, Zoom, Salesforce and more. You can get a deployment notification, approve it and see the result without leaving the channel. The Workflow Builder lets non-developers automate routine requests — time off, approvals, onboarding — without writing code.
AI features
Slack AI can summarise long threads and channels, answer questions based on your workspace, and generate daily recaps — genuinely useful when you return from a day away and face 200 unread messages. It is priced as an add-on per user, so evaluate whether your team will actually use it before enabling it.
The real costs
- Price per user — paid plans start at a few dollars per user per month and rise with features
- Attention — constant notifications fragment focus; most teams need explicit notification rules
- Message history limits on the free plan — older messages disappear from search
- Channel sprawl — unmanaged workspaces accumulate hundreds of dead channels
Free vs paid
The free plan supports unlimited users but limits message history and app integrations — workable for small groups and hobby projects, painful for anything longer-term because you lose search history.
Verdict
Best-in-class for teams that live in chat and depend on integrations. Set notification rules, archive channels aggressively and decide what belongs in a channel versus a document. If your company is all-in on Microsoft 365 and cost matters more than app ecosystem, Teams is the pragmatic alternative.
