I'm looking for an open-source alternative to Samsung Notes, which I use every day to take notes with my pen.
One of the main problems with this application is that you can't open a storage directly, every time I make a change to a document I have to export it manually to Nextcloud. You can't sync without Samsung Cloud.
Edit: This is an example of the usage I do of Samsung Notes and what I'm looking for:
Saber should be exactly what you need:
https://github.com/saber-notes/saber?tab=readme-ov-file
You can take handwritten notes and supplement them with text and images. It can also sync directly to your Nextcloud Account or sync via a Saber Server from the developer.
I used it for a while on my Boox tablet and it worked really well without many bugs or hiccups. I only switched to Notesnook because I stopped taking that many handwritten notes that had to be synced as well.
