I have been working on Obsidian for other purposes. I have started my UPSC prep with this app since 2023.
It has all the features required to make a comprehensive notes-
for eg,
1. Division in folders, files.
2. Calender to map progress.
3. We can embed YouTube videos, which is my favourite feature. You can embed playlists!
4. Embed pdfs, mp4 files, images.
5. You can make tags to find content easily. Like I have created tags from Syllabus itself.
6. Templates.
7. Excalidraw extension for graphs.
8. You can spilt the screen for long files.
9. Has tabs like google.
10. Ofcourse, allows to add links, and you can even link internal files.
