Strengths	Works like an engineer — takes Slack tasks, opens PRs Handles multi-hour engineering work Reports back with what it did	Real songs with real lyrics v4 is very good Quick turnaround	Tab completion feels like mind-reading Composer for multi-file edits Runs Claude, GPT, Gemini — you pick	Sources every claim Fast, current answers Pro Search runs multi-step research Spaces for persistent context

Kai's verdict	A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.	S-tier in its category. The first AI music tool I'd actually listen to.	S-tier for coding. If you write code of any kind, this pays back the $20 in a day.	S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
