Interesting tool based on blocks to tag any document for photos you own. With app to allow access from any device. Blocks contains tags and links between them to organize all like a heap.
I haven’t installed the self-hosted version yet to see how it can interact with an existing Obsidian vault. Next step.

Does it store uploaded files in plain text on the file system?
From what I can tell, notes are stored in the DB, but can be exported as JSON, or I think markdown. It sure about markdown. I’ve only been able to export JSON, and it didn’t include the image I had embedded in the note. Whatever isn’t a note (images, movies, pdf, doc, etc.) is stored on the file system in a directory structure that files them under heap -> asset checksum. Thumbnails are included there if applicable. In that regard, it kind of forces you to use its folder structure.
