The Todoist Project sync plugin enables seamless synchronization between Todoist projects and Obsidian notes. It automatically creates a note for each project, organizing them into a hierarchical structure that mirrors the project tree in Todoist. The plugin supports dynamic updates, such as archiving notes when projects are deleted, restoring them when projects are revived, and renaming or moving notes alongside project changes. Users can configure settings like sync frequency, the folder for Todoist notes, and specify a primary device to avoid sync conflicts. The notes include links to the respective Todoist projects and optional integration with the Todoist Plugin for displaying project tasks.
