Why choose Nifty or Twist?
Both tools offer add-ons, role management, contact management, chat, file sharing, mentions, groups/channels, GIF and emoji, and threads. However, Nifty offers more features such as voice messages, 1-1 video calls, multiple workspaces, AI, storage from 100MB, calendar, task management, and dedicated CSM. Twist does not offer these features, but it does offer a desktop app, on-premise option, and SAML/SSO authentication.
