Kai's verdictS-tier for coding. If you write code of any kind, this pays back the $20 in a day.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.B-tier overall, A-tier if GDPR/data residency matters. Solid backup option.
