Don't care about the ram or CPU I don't have performance issues and I could not care less that I might be in theory 1.5 fps. If performance is a concern, turn it off.

As for what I'd use it for, global transcriptions, better search, per page search in documents, local searchable documentation, summarization of long contacts, etc. if that's not useful, turn it off.

As for security, this is nothing worse than a locally cached session. If someone already has os level read and write your already fucked. Same with bitwarden or any other app storing credentials. At the end of the day is written to disk. If you don't like that turn it off.
