Kai's verdictA-tier. The right answer if you want open-source + terminal-native + model-agnostic.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.B-tier. Still early. Manus is more flexible for less money.
