Kai's verdictS-tier for academic research. Nothing else comes close for systematic reviews.A-tier. Niche but beloved. If you've outgrown Notion, try this.S-tier for text-in-image. Use this for posters, Midjourney for art.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
