Biggest strengthSlackbot's contextual awareness of your team's conversations and files eliminates constant app-switching — it actually knows what you've been working onReal-time collaboration is genuinely excellent — multiple designers can work simultaneously without conflicts or lagHighly customisable boards with 30+ column types adapt to virtually any workflow without coding
Biggest drawbackAI features like Slackbot and summarisation require paid plans, pricing out smaller teams who'd benefit most from automationPerformance degrades noticeably on complex files with hundreds of artboards or heavy plugins3-seat minimum on all paid plans means solo users and 2-person teams pay for unused seats

Common questions

What people ask about Slack

Straight answers to what buyers actually ask, drawn from the documentation and published user reports.

Is the free tier actually usable for a small team?
For 3-5 people doing casual coordination, yes. Beyond that, the 90-day message history and lack of AI features become painful. Users report upgrading around 8-10 people or when relying on Slack as a system of record.
How much does Slack actually cost per person?
Roughly £6-12/user/month for Pro (the tier most teams need), depending on annual vs monthly commitment. Enterprise Grid starts around £12-15+/user. Slack doesn't publish fixed pricing anymore, so expect 'contact sales' conversations for exact numbers.
Can I actually reduce email with Slack?
Yes, but only if your team commits. Users report 60% email reduction over six months, though that required clear channel structure, onboarding docs, and active moderation. Without process, Slack just adds to the noise.
Are the AI features worth paying for?
If you're losing 3+ hours per week to 'where did we discuss that?' then yes, AI search and Slackbot summaries justify Pro tier costs. If your team is under 10 people or well-organised already, they're nice-to-have rather than essential.
Is Slack better than Microsoft Teams?
Slack's UI is cleaner and AI features are more mature, but Teams integrates better if you're deep in the Microsoft ecosystem. If you already pay for Microsoft 365, Teams is included. If not, Slack is the better standalone product — just budget for it properly.
