Conceptboard vs Scribble Together

Conceptboard is a shared online whiteboard that combines visual collaboration with digital task management. It supports brainstorming, workshops, project planning, product roadmapping and team decisions. Boards can hold tasks, comments, templates and sections, with project organization, diagramming tools, presentation mode, an infinite canvas, workshop templates and voting tools. External guests can open a shared board without an account; guests and visitors are free on professional accounts. Conceptboard lists integrations with Microsoft Teams, Google Drive, Dropbox, OneDrive, Atlassian Confluence and Webex.
