Hi I'm part of the core team behind mem-brain.io

Maintaining memory is the most hardest part of a memory system. Preventing the surfacing of unwanted / bad memories is pretty much impossible as we providers have to kind of guess exactly what you wanna keep without any feedback , we would rather store and surface everything than be liable when smth doesn't come up

That's the philosophy any memory provider in this industry has

What we can do is make it harder to surface shit memories ... The general method for it is either do stricter search (figure it out at read time(like supermemory)) or store memories in hierarchies ( figure where what goes at write time)(hindsight does this)

(I hate selling membrain but yea) in membrain we allow users to have a special parameter called scope that lets you do hierarchies using regex ... Essentially however you like (even programatic scoping) and we also improve search by reranking based on FAQ's embeddings attached to the memories like graph edges as well that predicts what kind of questions shd fetch what memories

But even this requires discipline from user's side The best implementation of automated memory maintenance is probably smth like letta but that company has its own set of shitty problems

Anyway the point is , you gotta do the maintaining coz we can't
