Kai's verdictS-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.B-tier. Still early. Manus is more flexible for less money.A-tier for data teams. S-tier if you already live in SQL + Python.B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.
