| Kai's verdict | B-tier. Solid product but crowded market. Try it if Notion AI feels too generic. | S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week. | S-tier for local inference. If you care about privacy or want to tinker, install this today. | A-tier. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead. |
