What about this one that you’re on right now?

Good video!

Like you mentioned KDE Connect will sync your clipboard between Android and KDE. The KDE clipboard also has a history and you can run actions on clipboard entries which is super handy. I’m not sure about this snippets library, sounds like a permanent clipboard history that you can search, where the KDE one just keeps the last X copied things. I’d rather have my phone keyboard learn words I type a lot personally.
