Why choose ChatWork or Chanty?
Chanty, on the other hand, is a global solution with a G2 Score of 4.5/5. It offers add-ons for more guests and multi-conversation with guests, mentions, voice messages, 1-1 and group video calls, audio calls, and "Do not disturb" mode, among others. It has a starting price of $3/user/month, offers a free version for up to 10 users, and has a mobile, desktop, and web app. It also has customer support resources such as email, FAQ, forum, knowledge base, and chat. Chanty, however, lacks certain features such as contact management, workspace and user activity tracking, and task management.
