| Kai's verdict | S-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick. | A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google. | A-tier. The most interesting spreadsheet in years. Great for ops dashboards. | B-tier. Still early. Manus is more flexible for less money. |
