@moshtodon @liztai I don't know of any app aside from Obsidian that has all the following:
1. stores data in an interoperable plain text data format local to the device
2. does not have VC funding
3. does not include telemetry
4. has a flexible plugin API for both desktop and mobile
5. is actively maintained and improved
6. gets quick security patches, e.g. the recent CVE-2023-4863
7. has end-to-end encryption for sync between devices
8. is free for personal use
