    Our take

    Understanding Slack.

    Slack is professional messaging for communicating with clients and partners. Starting at €6.28/month. Built for managers and IT directors and SaaS founders.

    Estimated time saving: 3h/month.

    Keep it if: you collaborate with clients who use Slack or you manage a small team (2-5 people). Skip it if: you are a 100% solo freelancer (emails are enough) or your clients do not use Slack. As soon as you collaborate regularly with a team or clients who use Slack. Free alternative: discord.

    Slack: when it makes sense.

    As soon as you collaborate regularly with a team or clients who use Slack.

    Keep if

    You collaborate with clients who use Slack. You manage a small team (2-5 people)

    Slack becomes worthwhile when
    • You use it at least once a week
    • The monthly cost (€6) is small next to the time it saves you

    Challenge if

    You are a 100% solo freelancer (emails are enough). Your clients do not use Slack

    Slack becomes too expensive when
    • You use it less than once a month
    • discord (free) already covers the essentials for occasional use

    The AI angle

    Slack vs AI

    AI augments this tool
    Go further with AI

    Slack added Slack AI to summarize threads, answer questions about a channel's history and draft meeting recaps.

    Can AI replace it?

    Replace Slack with an AI? No: real-time team messaging and integration with dozens of tools remain a structural communication need. Verdict: AI summarizes what happens in Slack, it doesn't replace messaging.
