| Kai's verdict | 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. | A-tier. Niche but beloved. If you've outgrown Notion, try this. | A-tier. HeyGen wins for creators, Synthesia wins for enterprise. |
