| Kai's verdict | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | B-tier. Still early. Manus is more flexible for less money. | A-tier. Bet on this one — the Sparkpage format is genuinely new. | A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone. |
