Kai's verdictS-tier for solo + free. The best free option, hands down.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.
