Kai's verdictS-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.S-tier in the agent category. The first one I'd give to a non-technical friend.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.S-tier for speed. When latency is the product, start here.
