Well my question was specifically about smart prediction (beyond autocorrect). I have found scores of privacy friendly keyboards. The one I have been using for a year is from simplemobiletools (they have a full suite of apps and I use most of them ie contacts, gallery, notes…) but I miss the prediction feature. As you say even autocorrect is not yet supported in florisboard…but that wouldn’t be enough for me. Personalised dictionary based on typing would be a start, but swiftkey goes beyond, it proposes the next words before you type them
I haven’t tried it yet and indeed I just read his post from 3 weeks ago on how to get back on better tracks. I will give it a try but I couldn’t see from its description that it would go beyond its focus on privacy, at least for the moment
