A friend of mine set up a cron job coupled with the Claude API to process his email inbox every 30 minutes and unsubscribe/archive/delete as necessary. It could also be expanded to draft replies (I forget if his does this) and even send them, if you’re feeling lucky. I’m pretty sure the AI (I’m guessing Claude Code in this case) wrote most or all of the code for the script that does the interaction with the email API.

An example of my own, not agentic or running in a loop, but might be an interesting example of a use case for this stuff: I had a CSV file of old coupon codes I needed to process. Everything would start in limbo, uncategorized. Then I wanted to be able to search for some common substrings and delete them, search for other common substrings and keep them. I described what I wanted to do with Claude 3.7 and it built out a ruby script that gave me an interactive menu of commands like search to select/show all/delete selected/keep selected. It was an awesome little throwaway script that would’ve taken me embarrassingly long to write, or I could’ve done it all by hand in Excel or at the command line with grep and stuff, but I think it would’ve taken longer.

Honestly one of the hard things about using AI for me is remembering to try to use it, or coming up with interesting things to try. Building up that new pattern recognition.

No, the fact Claude couldn't remember that JavaScript is zero-indexed for more than 20 minutes has not left me interested in letting it take on bigger tasks
