Kai's verdictA-tier. The right answer if you want open-source + terminal-native + model-agnostic.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.A-tier. Genuinely different vibe from Suno — worth trying both for a month.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.
