Joplin – A note-taking and to-do app with builds for desktop, mobile, terminal
I'm currently using Apple Notes on my Mac and iPhone. It works just great!<p><pre><code>    It synchronises perfectly
    I can drag and drop images to it, no problem.
    Cmd + C, Cmd + V, Cmd + B, Cmd + I all work as expected.
    I can even add to-do lists and cross out "Done"
    I think it even supports tables, But I don't use them.
    Export as PDF, html, airdrop, email whatever, works easily
    </code></pre>
What doesn't work:<p><pre><code>    If I ever get out of Apple ecosystem, it won't work.
    Apple has my data, and I need to trust them.
</code></pre>
Give me something with the same ease of use, and make it self-hostable without pain. I'd be happy to pay. 
I don't need Markdown or anything else. Text + Drag & Drop images support are a must for me.
