Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.S-tier for speed. When latency is the product, start here.
