Personally, I think the worst possible use case is the one that's being pushed for; personalised agents.
I think a much better use case is one where it's not visible to the user at all, like spam filtering or helping an accountant do their monthly run in a few hours rather than a day. To me, that's likely a much better use of AI than trying to shove a chat interface or agent harness into an existing app.
That being said though, I did see a startup in my area basically offering a Resend/Mailchimp competitor as a Claude plugin, so maybe it'll just be integrations to their existing chat interface.
