Why choose Slack or Flock?
Slack offers more add-ons and features, including graphic personalization, voice messages, and breakout rooms, but Flock provides a more comprehensive task management system, notes-taking feature, and help resources. Both platforms offer chat, file sharing, mentions, and group video calls, but Slack also has whiteboarding and participant permissions, while Flock offers up to 20 participants in group video calls. Overall, Slack may be more suitable for larger organizations with complex integration needs, while Flock could be a better fit for smaller teams looking for a more affordable solution with robust task management and note-taking capabilities.
