Which product allows you to create to-do lists shared with many people?

Google Keep is the product that allows you to create to-do lists that can be easily shared with multiple people. It is a note-taking service that supports various formats such as lists, images, and voice notes, and its collaborative features make it particularly useful for group tasks. Users can share notes and to-do lists with others, enabling real-time collaboration. This means that when someone makes a change to the list, it is immediately reflected for all other users, enhancing teamwork.

In contrast, while Google Tasks is designed for creating to-do lists, its sharing capabilities are limited, making it primarily suited for individual use rather than collaborative tasks. Google Calendar is focused on scheduling and event management, which leaves it less equipped for to-do list functions, although it does allow for shared calendars. Google Drive is a cloud storage service that facilitates the sharing of files and folders, but does not specifically target task management or to-do lists. Therefore, the collaborative and sharing features of Google Keep make it the ideal choice for creating shared to-do lists.
