Kai's verdictS-tier in the agent category. The first one I'd give to a non-technical friend.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.A-tier. Close second to Cursor. If $5/mo matters, start here.
