I didn't follow your counterpart fixed now, maybe a match with https://cred.blue/home, if I connect with login can I save the keywords? a suggestion can be the date of the last post for the user you suggest
Quick update: busy with kontaktmaschine (https://koma.social), a keyword based recommendation tool (only for #Bluesky right now).
#Nostr is on the roadmap, but I wanted to start with the bigger firehose first😅.
Buggy BETA, but as always looking for any kind of feedback!
(kontaktmaschine is the successor to Discover Focus Engage.)

Yes, login persists keywords and already seen recommendations, so you do not see them twice.
