Kai's verdictB-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 realtime. If latency matters more than voice catalog, start here.A-tier for social/casual. B-tier for serious work. Good entry point.
