Backups: encrypted notes every ten minutes, code every night

Three small jobs copy everything that matters: my notes, my code, and the family app's files. When a backup falls behind or fails, I find out.

A Google Drive that tidies itself every month

I sorted out my Google Drive once with AI, then set a monthly task to keep it that way: it files new documents, renames them, removes duplicates and tells me what's about to expire.

The drop folder: I drop a file, AI files it

One folder on my computer takes any file. AI files it into my notes three times a day, I get pings, and the folder tidies itself every week.
