| Kai's verdict | A-tier for data teams. S-tier if you already live in SQL + Python. | S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time. | S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code. | A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google. |
