Every AI memory system currently shipping makes the same set of decisions on your behalf. It decides what about you is worth keeping. It decides when to summarise. It decides what gets pruned, and it does not tell you when something is gone.
None of that is a failure. It is the design. Automatic capture only works if something other than you is deciding what matters.
The result is a record of you that you did not write and cannot fully inspect. Most people find out what was dropped when the model answers as though it never knew.
