Why choose ClickUp or ChatWork?
Both platforms offer chat, file sharing, and groups/channels, but only ClickUp has the ability to mention users, poll, and create threads. ChatWork, on the other hand, offers 1-1 and group video calls, screen sharing, and audio calls, which ClickUp does not provide. ClickUp also has online document editing, document viewer, and document management, while ChatWork only has document management. However, ChatWork offers more storage per user, from 5GB to 10GB compared to ClickUp's minimum of 100MB. Overall, ClickUp seems better suited for a wider range of use cases, while ChatWork may be more appropriate for businesses in need of video conferencing and more storage.
