| Kai's verdict | S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week. | A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone. | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | S-tier. Category-defining UX. If you take notes in meetings, switch this week. |
