| Kai's verdict | S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week. | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | A-tier. Niche but beloved. If you've outgrown Notion, try this. | A-tier. Best for cinematic image-to-video. Pair with Runway for coverage. |
