Yes, ctx is the closest cousin here. I actually linked it in my top comment.

This causes a very similar itch, but we went a slightly different route regarding some implementation details

Secrets: The ctx README mentions saving the text as is and warns about the need to review the output data before publishing. deja explicitly removes known secret templates at the indexing stage (replacing them with tags like [redacted:aws-key]).

Syncing: It looks like ctx is getting ready for a cloud beta to be shared by the team. Actually, I just wanted something local and free that I had full control over, so deja does P2P syncing through your existing SSH settings.

Recall that deja has a session startup feature that automatically introduces a bit of context when a new agent is loaded, instead of relying solely on manual search.

Both applications solve the same annoying problem by simply optimizing for different workflows :)
