With the claude mods, you can now customize the claude desktop in a way that is very similar to how obsidian plugins work. The file explorer shows all folders including hidden ones in obsidian. No wysiwig edits, so only raw code edits possible, but do autosave like in obsidian.
I created a few claude mods to see how far it stretches and where the differences are.
The drawio works well, but the canvas rendering is missing the obsidian built-in support for bases and note previews.
Excalidraw looks good too , since the example is rather wide, ask for a transposition so added button in the panel and it works immediately ...
Still obsidian is my preference, but those Claude Mods open up a ton of possibilities if you decided to stick to the claude ecosystem.
