Is there a migration path from Obsidian or Notion? Switching costs are usually what keeps people locked in.
For Notion, we don't have a migration tool, but you can try the export to markdown approach.
Recommend trying it to get a feel, and if are looking to migrate and facing friction let me know details.
For example, with the appropriate plugins like dataview and charts, it's possible to create dashboards, lists, and tables that update automatically based on data elements present in documents or documents themselves. I use it to have views over my to-do lists (daily routine items, tasks that are overdue, upcoming tasks, etc), make dashboards, and show lists of documents edited on a particular date.
I'd love to migrate away from Obsidian towards something that's not proprietary, but I haven't seen anything that allows querying other documents.
That doesn't mean it's a design direction that open knowledge should go in, but just a data point that reducing Obsidian vaults to "just markdown" misses what some users use it for.
