Kai's verdictB-tier overall, A-tier if GDPR/data residency matters. Solid backup option.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.
