Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.A-tier. The strongest 'no-code' AI builder right now. Great for founder MVPs.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.
