Bottom line

Slack Pro is worth it if you're not in the Microsoft ecosystem

Slack Free is usable but the 90-day message history limit is genuinely painful. Pro at $8.75/user/mo gives full history, unlimited integrations, and Slack AI. If your company uses Microsoft 365, Teams is the pragmatic choice. If you're a tech-forward team that values integrations: Slack wins.

Common questions

Slack FAQ

Is Slack free for small teams?

Yes — free plan covers unlimited users, 90-day message history, and 10 integrations. The 90-day history limit is the main constraint for teams that need to reference older discussions.

How does Slack compare to Microsoft Teams?

Slack has better third-party integrations and is preferred by tech teams. Teams is free with Microsoft 365 and better for Office-heavy organisations. If you pay for Microsoft 365, Teams is the economical choice.

Does Slack have video calling?

Yes — Slack Huddles (audio/video) support up to 50 participants on paid plans. For scheduled video meetings with recording and larger groups, most teams use Zoom or Google Meet alongside Slack.

Is Slack AI worth it?

Slack AI (included with Business+ and higher) summarises channels, answers questions from message history, and recaps threads. Very useful for teams with high message volume. Not worth the upgrade just for AI alone.

Can I use Slack on mobile?

Yes — iOS and Android apps are fully featured, including Huddles and file sharing. Push notifications are reliable and customisable per channel.
