Frequently Asked Questions
What's the difference between Slack and Teams?
Slack excels in messaging experience and integrations with external apps. Teams is better if you use Microsoft 365 and need deep Office integration.
Can I use Notion instead of Slack?
We don't recommend it. Notion is excellent for documentation but not designed for real-time chat. Best to use Slack for communication and Notion for docs.
Which tool is cheapest for small teams?
All of them offer free plans. For teams under 10 people, the free tier of Slack or Notion may be enough. If you have Microsoft 365, Teams is completely free.
