Discord is a versatile communication platform that can be used for both personal and professional purposes, offering features such as voice and video calls, screen sharing, and direct messaging, making it a potential alternative to traditional chat apps like Slack or Microsoft Teams. The free version of Discord has limited file uploads and does not offer official integrations with business-facing apps, but it can be supplemented with user-created bots and Zapier integrations. Companies can use Discord for internal communications, client communications, community-building, audience research, image generation, and automating workflows, making it a viable option for businesses looking to build a community or streamline their communication processes.
