Kai's verdictA-tier. Niche but beloved. If you've outgrown Notion, try this.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.A-tier. Great price/performance. Go here if ElevenLabs is too expensive.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
