Joplin works well for me.

Opera one has messengers integrated in the sidebar. Really nice concept but PWA and masto lemmy etc are missing as an option.

I tried quay.io/go-skynet/local-ai but my Server lacks the Cpu instruction set for it.

Its a collection of models you can download. It acts as a simple gui entry point into the llm world. Great to test different stuff.

Yunohost might be a good point to start? Havent tried it yet but it seems to be a fast and safebway to host.
