Comparison
Adda vs Slack
Slack is a chat app that connects to other tools. Adda is chat plus the tools themselves: projects with sprints, collaborative documents, OKRs, whiteboards, a calendar and audio or video calls in one private workspace. Teams under 10 people use Adda for free, so a small team can replace Slack and three or four other subscriptions with one login.
