Kai's verdictA-tier. Niche but beloved. If you've outgrown Notion, try this.A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.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.
