Kai's verdictA-tier. The right answer if you want open-source + terminal-native + model-agnostic.A-tier. Close second to Cursor. If $5/mo matters, start here.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.
