I tried Matter but it lacked Android support at the time so didn't go deep into it. I've been a heavy Readwise user for the last two years or so. It's better than Pocket in almost every way, although as I've moved into the 99.9th percentile of archive size I'm seeing some annoying perf issues they'll hopefully fix. At least they have a Discord and are making actual updates to the app, something that Pocket stopped doing probably five years ago.
