It sounds like what they ultimately want is one place to look at both read-it-later stuff and starred RSS articles. My read is that they are proposing one way to do it, but ultimately it’s not super workable that way. There are no clients I know of that are both RSS clients and read-it-later clients (using pocket, wallabag, or anything else).

If OP wants one place to see both, their best bet is to find a read-it-later server that can generate RSS feeds, subscribe to those, and now everything is RSS and behaves the same. Wallabag is a great option for that and is self-hostable.

This is exactly what I do and it works great.

http://wallabag.it/ can publish your read-it-laters to RSS

I use the FUTO keyboard. The “AI” features that it includes are local-only predictive text and voice-to-text (both are very good, in my experience). It’s not open source, and neither is GrayJay (another FUTO project), which is a yellow flag, at minimum.

At the same time, they do fund open source projects, most notably Immich, which is a fantastic Google Photos alternative. I’m personally okay with using their stuff, and tentatively happy with them as an organization, but I’m keeping a watchful eye on their behavior.
