Kai's verdictB-tier. Solid product but crowded market. Try it if Notion AI feels too generic.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.S-tier. If you're on Vercel/shadcn, this is cheating.A-tier. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead.
