I am thinking about using Obsidian (+ scripts) for my regular text encryption needs.
Encrypted text data tends to be valuable and I am done with all these proprietary programs leaving you to hang.
Plus search doesn't work for encrypted text in Evernote.

There is also Standard Notes which comes with good encryption or Day One Journal in case you used encrypted text primarily for journalling.
For one-off standalone notes that need to be encrypted, I am considering a password manager like Bitwarden. It allows export of data so I believe I will not be locked in.
