Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.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. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.
