Kai's verdictB-tier. Solid product but crowded market. Try it if Notion AI feels too generic.A-tier. Close second to Cursor. If $5/mo matters, start here.S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.A-tier. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead.
