Kai's verdictB-tier. Solid product but crowded market. Try it if Notion AI feels too generic.A-tier. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead.S-tier for designers. The only one that takes vectors seriously.A-tier. The right answer if you want open-source + terminal-native + model-agnostic.
