OneDrive is primarily a personal file storage and synchronization service that allows users to store their files in the cloud and access them from anywhere with an internet connection. It is designed for individual users and allows them to easily share files with others, both inside and outside their organization.
SharePoint, on the other hand, is a collaboration platform that allows organizations to create websites, manage content, and share files and information with team members, partners, and customers. SharePoint offers many features beyond file storage, such as document creation, workflow automation, and team collaboration tools.
