Typora is a simple Markdown editor. It is not directly comparable to DEVONthink except in the minor fact that you can compose Markdown in DEVONthink and DEVONthink To Go as well.
Organizing data is straightforward – each folder represents a database, containing markdown files and associated assets (e.g., ABC.md with images in assets/ABC.assets). This structured approach makes it easy to locate referenced images or attachments when moving files.
This is nothing new nor anything Typora invented. It’s a very common mehotd, having been used in web development for decades now. In fact, I have long used and advocated this approach in DEVONthink.
But if Typora suits you, by all means, enjoy!
