| Kai's verdict | B-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 multilingual video. If you sell courses or speak at events, this is a cheat code. | S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week. |
