Notion – All-in-one workspace for notes, tasks, wikis, and databases
I made a Python API wrapper in case annoying would find it useful: https://learningequality.org/r/notion-py-an-unofficial-pytho...It has full read/write support for Notion data, with a local data store that live-updates async when data changes on Notion, including callbacks. And you can manipulate database entries using classes with columns mapped to slugified attributes.
