Documentation on import methods we currently support.
Currently we support Workflowy and Roam as native import formats. Check out Tana Intermediate Format to see an early version of community-supported importers for Logseq and Obsidian, and how you could contribute to build an importer for your favorite format.
Imported content is placed either under the new workspace's Library, or under the appropriate daily page depending on the contents of your import file.
