Kai's verdictA-tier for data teams. S-tier if you already live in SQL + Python.S-tier in its category. The first AI music tool I'd actually listen to.S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
