Hi everyone,
this (GitHub - anhi/obsidian-notion-connector) plugin connects Obsidian to Notion via the official javascript SDK. At this stage, the connection is one-way (download from Notion to Obsidian), but future releases will add at least limited two-way communication.
Right now, the plugin can download pages and databases from Notion. Database entries are stored in a separate folder, with one note per entry, and rendered through the Database folders plugin.
