Hello @recaremo, and welcome to the forum!
What exactly do you mean with copy:

Here you can inform yourself about the abilities of Krita’s new Text Tool, which will be something, many state, no other painting software offers. Especially the first post and the last ~30 postings are quite informative in my eyes:
The Krita NEXT-Nightly versions can be found here:
