Kai's verdictB-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.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.
