Kai's verdictB-tier. Solid product but crowded market. Try it if Notion AI feels too generic.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.B-tier. Still early. Manus is more flexible for less money.S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.
