Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. S-tier if you self-host. The reason open-source image gen matters.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.
