Kai's verdictB-tier. Solid product but crowded market. Try it if Notion AI feels too generic.A-tier. Best free agentic option in VS Code. Use with Claude for best results.A-tier. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
