Core Statements
Mosaic is a desktop application for Windows and macOS. Mosaic is published by Mosaic Desktop, Inc., a company with a registered address in Pasadena, California, United States. Mosaic connects to Google Workspace, Microsoft 365, and, on macOS, Apple Calendar. Mosaic can also work with specific files and folders on the user’s own computer that the user chooses to share with it. Those are not connectors, because they are not cloud data. Mosaic gathers material from the applications and files the user gives it access to and presents ranked suggestions. Mosaic sends an email on the user’s behalf only after the user reviews it or explicitly asks it to, and creates or changes a calendar event only when the user approves it or explicitly asks it to. Material from a connected cloud account is brought to the user’s own computer and worked on there. The website for the product is www.mosaicdesktop.ai.
