Check out @ZAI
An ai nostr account that will react to your nostr posts.
But nothing is free (right?) so to use zai you need to top it up with some sats (just zap it to add a balance).
It is really impressive how co-pilot produces code now, the level of code it can write will take me probably many hours even days, with ai it takes 5min.
I find the trick is to write very detailed prompt and break big tasks to small iteration steps.
