Microsoft is officially launching its Notion-like productivity and collaboration app called Loop. From a report: Loop lets you use flexible, collaborative workspaces and pages to make it easier to cooperate on work. If you're familiar with Notion's interface at all, Loop looks and feels remarkably similar -- right down to the ability to easily access a bunch of tools and formatting options by typing the forward slash key (which pulls up what Microsoft calls the "insert menu"). But because Loop is built by Microsoft, that means it has some useful integrations with other Microsoft software.
