| Kai's verdict | 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. | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code. |
