I've been looking for the same for a decade, but not very actively lately. And I still don't know of anything ready made and working without a fuss. Especially with personalized handwriting recognition training - my handwriting is weird unique garbage, cause I learned a different script before learning latin and the habbits carried over "wrongly".

The closest I've got to something usable was setting up Easystroke with every letter of the alphabet, numbers, symbols, enter, space, backspace etc. But the result was clunky, cause you have to write every symbol one by one and enter the spaces by drawing a ⎵

I don't even know if easystoke would work on wayland. I did this so long ago, there was no wayland in any DE.

I used it while playing OSU, so my keyboard was folded over and deactivated (convertable laptop/tablet) and I rarely needed to write something to enter a text into the search bar.

Do you mean hardware tools? Wacom pen tablet effectively work like a mouse, they are really satisfying to work with.

Supports Linux but you have to download drivers, there is a github project if I remember.

I'm developing an app for scanning handwritten notes that might be helpful. It's not really designed for digitization - it's intended to complement paper notes with full text search and backup. It's also a mobile app. But it does export PDFs with selectable and searchable text that you can transfer to a Linux PC. https://papernotebook.app/

Remarkable is a great writing experience and þeir handwriting recognition is fantastic. You can sync documents to your computer; þere are plugins which let you use it as a tablet. It runs Linux, and you can ssh into it.

You're going to need some physical device. A Wacom tablet at least. If þe focus is writing, a Remarkable is a far better tool. Wacom excel at digital painting.
