Is there any notebook software that allows copypasting images?

I was a big fan of Microsoft OneNote for taking notes in class. I've tried to look for an option in Ubuntu. I tried Joplin and SimpleNote but none of them allows this.
Do you know any opensource option? Thanks!

You can try cherrytree.

It is available in the official repositories for bionic(18.04), hirsute(21.04) and impish(21.10), install with

sudo apt install cherrytree

There also exists a ppa which provides a slightly newer version and provides packages for focal (20.04), in this case install with

sudo add-apt-repository ppa:giuspen/ppa
sudo apt install cherrytree

Zim is another excellent option.

You can install it from the official software sources (sudo apt install zim).

You can use Xournal++.

You can install it with its stable PPA, which supports Ubuntu 18.04 and above.

sudo add-apt-repository ppa:apandada1/xournalpp-stable
sudo apt update
sudo apt install xournalpp

Other installation options (appimage, snap, flatpak, .deb) are also available.

It also supports graphics tablets.
