| Kai's verdict | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week. | S-tier for ad-hoc analysis. Makes you feel like a data scientist in 30 seconds. | A-tier. Best for cinematic image-to-video. Pair with Runway for coverage. |
