Kai's verdictS-tier for academic research. Nothing else comes close for systematic reviews.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.
