I'm a happy self-hosted Monica user, I like that I have alerts set to remind me of birthdays and other events, and that there's a place to list, e.g. everyone who got a Christmas card from me last year. I recommend it to people.

I'm agnostic about a rewrite, I never used Chandler and as far as I'm concerned it's perfectly serviceable for me the end user as it is. I rarely use the UI. I have been contemplating interacting with it more agentically, maybe having a bot update the record that I had a beer with someone instead of doing it by hand, but I like that it's focused.

I have started musing about how I might bridge it to other systems, like the people I have resolved from faces in my Immich photos, but I neither want or expect Monica to do this for me.
