I've been using it daily, so far it's built CLIs for hackernews, BBC news, weather, a todo manager, fetching/parsing webpages etc. I asked it to make a daily briefing one that just composes some of them. So the first thing it runs when I message it in the morning is the daily briefing which gives me a summary of top tech news/non-tech news, the weather, my open tasks between work/personal. I can ask for follow ups like "summarize the top 5 stories on HN" and it can fetch the content and show it to me in full or give me a bullet list of the key points.

Right now I'm thinking through how to make it more "proactive" even if it's just a cron that wakes it up, so it can do things like query my emails/calendar on an ongoing basis + send me alerts/messages I can respond to instead of me always having to message it first.
