Kai's verdictA-tier. Close second to Cursor. If $5/mo matters, start here.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.S-tier for solo + free. The best free option, hands down.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.
